I'm ready when u are ...sry I don't get off work till 330 or 430
Customer: replied 12 days 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 12 days 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 12 days 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 12 days ago.

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

Customer: replied 12 days ago.
I see
Expert:  david craig replied 12 days ago.

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

Customer: replied 12 days 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 12 days ago.

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

Expert:  david craig replied 11 days ago.

checking in to see how its going

Customer: replied 10 days ago.
Kinda cant really tell with other light below it on ...lookz like occasionally it flickers
Expert:  david craig replied 10 days 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 10 days 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 10 days ago.

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

Customer: replied 10 days ago.
It dont it stays and flickers like it wants to go completly out or completely on
Expert:  david craig replied 10 days ago.

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

Customer: replied 10 days ago.
It does shows 12.5 something and when i got started once it jumps to 14.7
Expert:  david craig replied 10 days 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 10 days ago.
Ok thanks
Expert:  david craig replied 10 days 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 10 days 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 10 days ago.

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

Customer: replied 10 days 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 10 days ago.

thats fine, just let me know if it works.

Customer: replied 10 days ago.
OK will do

Customer: replied 8 days 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 8 days ago.

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

Customer: replied 8 days ago.
Once I got it started it stayed running until I shut it off
Expert:  david craig replied 8 days ago.

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

Customer: replied 8 days ago.
No went looking for that imobilzer
Expert:  david craig replied 8 days 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 8 days 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 8 days 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 8 days ago.

heres the keyless entry module/security module

in the trunk

Customer: replied 8 days ago.
should I try and clean that up since its in trunk ?now would bad ignition switch do something
Expert:  david craig replied 8 days 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 8 days ago.
Fine no issues at all ....except the dash is lit up like a Xmas tree
Customer: replied 8 days ago.
Temp gauge don't work so I don't think it's letting fan turn on to cool it
Expert:  david craig replied 8 days ago.

i think you got a computer issue. my friend.

Customer: replied 8 days 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 8 days 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 8 days ago.
Thanks I think
Expert:  tims auto repair replied 8 days ago.

Expert:  tims auto repair replied 8 days ago.

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

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

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

the code you gave me 1675 is a computer driver code

Expert:  tims auto repair replied 7 days ago.

the terminals on the computer may be corroded and needs cleaned

Expert:  tims auto repair replied 7 days ago.

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

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

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

Expert:  tims auto repair replied 7 days ago.

it is a driver that controls the evap solenoid

Expert:  tims auto repair replied 7 days 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 days 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 days 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 days ago.
I should possibly look into replacing crank sensor ?are they know to just go out
Expert:  tims auto repair replied 7 days 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 days 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 days ago.

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

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

yes and injector pulse..

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

Expert:  tims auto repair replied 7 days ago.

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

it isnt the immobilizer ,,the starter is turning

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

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

Customer: replied 7 days 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 days ago.

electronic parts cleaner should be fine

Expert:  tims auto repair replied 7 days ago.

sorry,,this one does have a passlock..

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

does the security light stay on with the key on?

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

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

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

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

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

ok

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

Customer: replied 7 days 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 days ago.

did the security light go out after those 10 minutes?

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

ok

replace your key lock cylender

Expert:  tims auto repair replied 7 days 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 days ago.
I need to replace ingnition switch
Expert:  tims auto repair replied 7 days 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 days ago.
What the difference between the two
Expert:  tims auto repair replied 7 days 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 days 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).

Customer: replied 7 days ago.
Or the tool needed to check it
Expert:  tims auto repair replied 6 days ago.

Customer: replied 6 days ago.
What I didn't get anything
Expert:  tims auto repair replied 6 days ago.

you nwant to check what plug?

have you replaced the lock cylinder?

Customer: replied 6 days 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 days 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 days 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 days ago.

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

Expert:  tims auto repair replied 6 days ago.

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

Customer: replied 6 days 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 days ago.
No ones got lock gotta order
Customer: replied 5 days ago.
Still waiting on answer
Expert:  tims auto repair replied 5 days 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 5 days ago.
Y would dash light up then and gonna be few days before get lock
Expert:  tims auto repair replied 5 days 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 4 days ago.
were do u recommend starting first
Expert:  tims auto repair replied 4 days ago.

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

Expert:  tims auto repair replied 1 hour 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 1 hour ago.
Do I need another person to help with that
Expert:  tims auto repair replied 1 hour ago.

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

thanks
