I'm ready when u are ...sry I don't get off work till 330 or 430
Customer: replied 7 months ago.
I can't really afford to pay extra 26 dollars now ..especially after being told 5 for deposit to which is get back then turn around and be charged another 13 dollar's grand total of 18$...so hopefully this works
Expert:  Chris (aka- Moose) replied 7 months ago.

What is the fuel pressure with the key on and when it starts and stalls?

Are there codes stored?

Once started can you get it to stay running with throttle applied?

Customer: replied 7 months ago.
Me pump and don't know fuel pressure at rail..when I get it started it runs fine and I can push gas peddle refs up and down fine ..not as its running when it runs all dash lights like when u first turn on are on and temp and rpm gauge don't work
Expert:  Chris (aka- Moose) replied 7 months ago.

I do not believe I can figure this out from this information. I will opt out.

Customer: replied 7 months ago.
I see
Expert:  david craig replied 7 months ago.

Hi Im David. could you please be a bit more clear about whats going on with your vehicle? thank you.

Customer: replied 7 months ago.
Well I park it and it ran well it sat about two months cause didn't need it so I went out just start it and it started but ran few seconds and I keep restarting it and it finally started a ran but once I shut it off it did same thing so I change fuel pump figured it was weak ...got better pressure but still does same thing ...acts like anti theft is on ...all the normal lights that when you first turn key on to start is on ....when I get it to run which got to do last night they stay on and no rpm gauge no temp gauge ...but u can watch rpm gauge move when u turn key off and on ...I've heard they that year had a messed security system in them for the dash cluster ..would this cause my problem ...check all the grounds on the block to make sure they got good ground
Expert:  david craig replied 7 months ago.

ok, thanks for the info. when you try to start the car does the security light go out?

Expert:  david craig replied 7 months ago.

checking in to see how its going

Customer: replied 7 months ago.
Kinda cant really tell with other light below it on ...lookz like occasionally it flickers
Expert:  david craig replied 7 months ago.

if the security light isnt going out when you turn the key to the start position, your immobilizer has you locked out. so please make sure. "i cant really tell" isnt helping.

Customer: replied 7 months ago.
How do u varify it ?all the dash lights like when u first turn key on is on and i think its the battery light is on and just above that is security light ....
Expert:  david craig replied 7 months ago.

when you try to start the car, the security light should go completely out

Customer: replied 7 months ago.
It dont it stays and flickers like it wants to go completly out or completely on
Expert:  david craig replied 7 months ago.

ok. check the voltage at the battery with a meter. make sure its got a full charge at 12.5 vdc

Customer: replied 7 months ago.
It does shows 12.5 something and when i got started once it jumps to 14.7
Expert:  david craig replied 7 months ago.

ok, 12.5 is good. 14.7 is not. it should read 14.4...we'll worry about that when we get it started again.

Customer: replied 7 months ago.
Ok thanks
Expert:  david craig replied 7 months ago.

your immobilizer has you locked out from starting the car if the security light doesnt go out while trying to start. disconnect the battery cables and hold them together for 20 seconds then reconnect them. see if that clear up any problems.

Customer: replied 7 months ago.
Its gonna take me awhile to get to i had to go into work till 430 ...is that a problem
Expert:  david craig replied 7 months ago.

im back, had to run to hospital...were you able to do that?

Customer: replied 7 months ago.
I'm still at work due to weather here ..so I'm not gonna be able to get to that till morning.. If that's OK and hopefully everything is OK
Expert:  david craig replied 7 months ago.

thats fine, just let me know if it works.

Customer: replied 7 months ago.
OK will do
Expert:  david craig replied 7 months ago.

thanks

Customer: replied 7 months ago.
I tried the test u gave me to do with putting wires together didn't work ,but got cr to restart took pic if u need it to see dash ....let warm up and shut it back still does is ..now what
Expert:  david craig replied 7 months ago.

the car started and shut down? how long before it shutdown?

Customer: replied 7 months ago.
Once I got it started it stayed running until I shut it off
Expert:  david craig replied 7 months ago.

have you tried to disconnect the battery again and see if that works again?

Customer: replied 7 months ago.
No went looking for that imobilzer
Expert:  david craig replied 7 months ago.

if it keeps starting every time you disconnect and reconnect the battery and that security light never goes completely out. it will be an immobilizer problem and only correctable at the deler level. they will need to recut and recode new keys.

Customer: replied 7 months ago.
What do u mean recut keys ?can u replace ignition or immobilizer or test the immobilizer?were they say immobilizer is I'm not finding it on my 96
Expert:  david craig replied 7 months ago.

no test for immobilizer. it either lets you start the car or doesn't. based on the security light not going out upon cranking

Expert:  david craig replied 7 months ago.

heres the keyless entry module/security module

in the trunk

Customer: replied 7 months ago.
should I try and clean that up since its in trunk ?now would bad ignition switch do something
Expert:  david craig replied 7 months ago.

ignition switch wouldnt do it. it starts, even though it stalls. lets not even worry about the security module anymore since it starts and runs til you shut it down. when it is running how does it act?

Customer: replied 7 months ago.
Fine no issues at all ....except the dash is lit up like a Xmas tree
Customer: replied 7 months ago.
Temp gauge don't work so I don't think it's letting fan turn on to cool it
Expert:  david craig replied 7 months ago.

i think you got a computer issue. my friend.

Customer: replied 7 months ago.
how's it going from immobilizer not working properly to no one of my computers in or out of car is messed up
Expert:  david craig replied 7 months ago.

because of the fact that the security light wont fully go off. but since its starting and running until you shut it off then that rules out the security system. im going to opt out and let someone else give it a shot. good luck

Customer: replied 7 months ago.
Thanks I think
Expert:  tims auto repair replied 7 months ago.

Hi, My name is ***** ***** for the delay.

Expert:  tims auto repair replied 7 months ago.

ok

and now it just starts and stalls?

Customer: replied 7 months ago.
Yea most of the time ...but if I try and start it for a bit it'll sometimes catch and run till I shut it off
Expert:  tims auto repair replied 7 months ago.

ok

does the engine light stay on?if so,can you give me the trouble codes?

Customer: replied 7 months ago.

I scanned car only code showing is evap code 1675
Expert:  tims auto repair replied 7 months ago.

this is a quad driver code from the computer..

disconnect the wire harness from the computer and clean the terminals on the pcm[computer] and the harness plugs with electronics parts cleaner.

Expert:  tims auto repair replied 7 months ago.

it is possible for you to have a bad pcm and needs to be replaced

Customer: replied 7 months ago.
Not really understanding shat you're telling me
Expert:  tims auto repair replied 7 months ago.

the code you gave me 1675 is a computer driver code

Expert:  tims auto repair replied 7 months ago.

the terminals on the computer may be corroded and needs cleaned

Expert:  tims auto repair replied 7 months ago.

the computer may be bad..or you could have a broken wire in the harness

Customer: replied 7 months ago.
That code off scanner said evap not pcm
Expert:  tims auto repair replied 7 months ago.

click the link..i gave you the code definition and tests for 1675

Expert:  tims auto repair replied 7 months ago.

it is a driver that controls the evap solenoid

Expert:  tims auto repair replied 7 months ago.

if it is giving a bad driver,,and sense the car did sit for a while,the ternals on the computer may be dirty.may be why iit wont run also

Expert:  tims auto repair replied 7 months ago.

if it still wont run after you check/clean the terminals at the computer..i think you may have a bad 7x crank sensor

Customer: replied 7 months ago.
OK as soon as I get back home I'll check it out ...now would that cause cr to start and shut off after view seconds then occasionally catch and start and run fine ?van I get used pcm or reset this one
Customer: replied 7 months ago.
I should possibly look into replacing crank sensor ?are they know to just go out
Expert:  tims auto repair replied 7 months ago.

yes,,the crank sensor or the ignition module on these can just quit..

clean the terminals on the computer and plug first

Customer: replied 7 months ago.
I can't for the life of me find the ignition control module ...looked on passenger side nothing trunk nothing
Expert:  tims auto repair replied 7 months ago.

the ignition module is under the coils..it is what the coil mounts to

Customer: replied 7 months ago.
that just controls spark ?
Expert:  tims auto repair replied 7 months ago.

yes and injector pulse..

the computer[pcm]is under the dash on the passenger side

Customer: replied 7 months ago.
I was looking for immobilizer
Expert:  tims auto repair replied 7 months ago.

it isnt the immobilizer ,,the starter is turning

Customer: replied 7 months ago.
I found computer for inside
Customer: replied 7 months ago.
OK cause last guy said some what that would cause it to start but stall
Expert:  tims auto repair replied 7 months ago.

clean the terminals on the coomputer and the plugs to it..

this one doesnt have a passlock system started in i think 98

Expert:  tims auto repair replied 7 months ago.

The Ignition Control Module is located under the coil pack assembly.

Customer: replied 7 months ago.
Oh OK explains y I can't find it lol as soon as I get apart and clean certain cleaner I should using ?I got electrical end cleaner
Expert:  tims auto repair replied 7 months ago.

electronic parts cleaner should be fine

Expert:  tims auto repair replied 7 months ago.

sorry,,this one does have a passlock..

Customer: replied 7 months ago.
OK do u have an idea were its at
Expert:  tims auto repair replied 7 months ago.

does the security light stay on with the key on?

Customer: replied 7 months ago.
As just turned or started ?it is when turn key forward and flickers when I get running
Expert:  tims auto repair replied 7 months ago.

does it stay on in the run position,,not start?

Customer: replied 7 months ago.
we tryed resetting I think
Expert:  tims auto repair replied 7 months ago.

3. Turn the ignition switch from the OFF position to the CRANK position attempting to start the vehicle. The vehicle will start and then stall. 4. Leave the ignition switch in the ON position while observing the security indicator.[this is the security light] 5. When the security indicator turns off, which can take up to 10 minutes, turn the ignition switch off. Wait 10 seconds. 6. The BCM and the PCM will learn the new code on the next start attempt.

Customer: replied 7 months ago.
OK will try but think we did that and I think it restarted a little faster but I'll do it again ..it'll take a bit tho
Expert:  tims auto repair replied 7 months ago.

can you take the phone call option..i would like to talk to you

Customer: replied 7 months ago.
I would but can't afford right now to spend 26$
Customer: replied 7 months ago.
I'm running ten minute test now and already cleaned pcm terminals
Expert:  tims auto repair replied 7 months ago.

ok

if the light never gos out or flashes..you may need to replace the key lock cylender

Customer: replied 7 months ago.
how am I supposed to know that ?so far there's three different things that it might be ...so how am I gonna be able to narrow down without replacing all three
Expert:  tims auto repair replied 7 months ago.

did the security light go out after those 10 minutes?

Customer: replied 7 months ago.
It still flickered and occasionally popped on
Expert:  tims auto repair replied 7 months ago.

ok

replace your key lock cylender

Expert:  tims auto repair replied 7 months ago.

the key cyl;ender,the ignition switch and the pcm[main computer] are the componants of the passlock..the lock cylender can go bad and not let the light go out

Customer: replied 7 months ago.
I need to replace ingnition switch
Expert:  tims auto repair replied 7 months ago.

i would think the lock cylinder..and the switch is also possible,the the lock cylinder is most likely..

there is no good test

Customer: replied 7 months ago.
What the difference between the two
Expert:  tims auto repair replied 7 months ago.

it has a key lock cylender for the key..and it has the electrical ignition switch that the key lock turns..

Expert:  tims auto repair replied 7 months ago.

The PASSLOCK TM System is designed to prevent vehicle operation if the mechanical key is not used to start the vehicle. The mechanical key, in normal operation, will turn the PASSLOCK TM Lock Cylinder. The PASSLOCK TM Lock Cylinder will relay a Resistance Code (R-Code) to the Instrument Cluster . The Instrument Cluster will determine the validity of the R-Code within a preset time window started from an Ignition Switch input and will send a coded password ***** the Powertrain Control Module (PCM). When the Powertrain Control Module (PCM) receives the correct code, it will allow the Fuel Injectors to operate normally. This system is similar in concept to the Passkey System; however, PASSLOCK TM eliminates the need for a key mounted resistor pellet. The components of this system are as follows: PASSLOCK TM Lock Cylinder, Ignition Switch, Instrument Cluster and Powertrain Control Module (PCM).

I've read both ur download apps ..but I understand the logic to it but I don't understand how and were to find plug to check voltage
Customer: replied 7 months ago.
Or the tool needed to check it
Expert:  tims auto repair replied 7 months ago.

.

Customer: replied 7 months ago.
What I didn't get anything
Expert:  tims auto repair replied 7 months ago.

you nwant to check what plug?

have you replaced the lock cylinder?

Customer: replied 6 months ago.
No the one they had the plug its got doesn't have same plug ..trying to hunt one down ...according to that site u sent it told me to check ohms going to pcm and lock
Expert:  tims auto repair replied 6 months ago.

yes,,you just need a multi meter to test the ohms..

you can have the lock cylender replaced quicker than you can do the tests

Customer: replied 6 months ago.
Yea got it out already just the one I need no one seems to have and there not cheap either lol..can I check at plug of lock switch were it plugs in to see if its getting the proper ohms or us tger a way to check lock switch
Expert:  tims auto repair replied 6 months ago.

i dont know of a good way to test the lock when it sets the passlock..

Expert:  tims auto repair replied 6 months ago.

after you replace it,you will need to do the passlock relearn procedure

Customer: replied 6 months ago.
Now just curious would the ignition switch on back side do same thing ?pulled lock out after turning key forward onto on position used screwdriver to try and start still same thing but right after I put back in after few turns it started up and ran ..still dash lights and flickering security system but cooling fan turned out when it got warm ..shut off back at same issue
Customer: replied 6 months ago.
No ones got lock gotta order
Customer: replied 6 months ago.
Still waiting on answer
Expert:  tims auto repair replied 6 months ago.

you need to replace that lock..

yes,it is possible for the switch itself to do this also..

agian,i am going on the security light staying on,,if the light isnt staying on,,the problem may not be the security at all..and may be the ncrank sensor or the ignition module

thanks

Customer: replied 6 months ago.
Y would dash light up then and gonna be few days before get lock
Expert:  tims auto repair replied 6 months ago.

?..

again,the cluster,switch.computer and lock cylinder are your security components.

if the security light is staying on and not going off when doing the relearn..the common thing to cause this is the lock cylinder..again,,either of these could be the problem.

if the security light isnt staying on,then your problem may be the crank sensor or the ignition module going on what you are telling me...

if the dashis acting up,,then you may have a bad ignition switch or bad cluster..

thanks

Customer: replied 6 months ago.
were do u recommend starting first
Expert:  tims auto repair replied 6 months ago.

sense you are talking about the cluster acting up..i would replace the switch first

Customer: replied 6 months ago.

Key cylinder and switch are supposed to be in sometime today if that's the problem will the lights on cluster go out and do I need to relearn before I try and start it ?
Expert:  tims auto repair replied 6 months ago.

yes,,and yes you will need to do the relearn for it to start

thanks

Customer: replied 6 months ago.
Is it best to replace both of those or just one
Expert:  tims auto repair replied 6 months ago.

if you got them,may as well replace them both while you are working on it

Customer: replied 6 months ago.
Only reason I asked once I change key cylinder it won't march doors no more ...if ignition switch fixes it
Expert:  tims auto repair replied 6 months ago.

that is correct.

try the switch first.

Customer: replied 6 months ago.
The best ideas to replace the ignition switch first
Customer: replied 6 months ago.
Did all that and now security light is fully flashing even with key out
Expert:  tims auto repair replied 6 months ago.

Remove both battery cables from the battery, turn on the ignition,touch and hold both the - and the + cables together for 5 seconds, turn off the ignition,then re-install them back to the battery..then do the relearn

let me know if this fixed the problem

Customer: replied 6 months ago.
Do I need another person to help with that
Expert:  tims auto repair replied 6 months ago.

?/..no..i sent you the relearn procedure earlier

thanks

Customer: replied 6 months ago.
Yea I know the relearn part ignition turned on for ten minutes Waite ten seconds then try it
Customer: replied 6 months ago.
Did test and relearn didn't work
Expert:  tims auto repair replied 6 months ago.

does the security light go off now?

Customer: replied 6 months ago.
No
Customer: replied 6 months ago.

Expert:  tims auto repair replied 6 months ago.
