I have attached the starter relay wiring diagram.

Can you remove the starter relay and tell me if pin 86 has 12v when you try and start it? Then clip the test light to positive battery and probe pin 85 and tell me if it has a ground signal when starting..

Talk soon,

Brad

Do you see a red light on in the dash?

Customer: replied 1 year ago.
all the lights work on dash,, gages no
Expert:  -Brad- replied 1 year ago.

When you turn the key on does the check engine light come on? When did it begin not starting?

Customer: replied 1 year ago.
no check engine,, it started last week, then fri no start
Expert:  -Brad- replied 1 year ago.

If the check engine light does not come on when you turn the key on then the PCM is not coming on.. I attached the wiring diagram for the PCM.. Can you verify it has 12v and ground... Also turn key on and see if MAP or TPS has 5v on the Orange reference wire..

Customer: replied 1 year ago.
where is pcm located
Expert:  -Brad- replied 1 year ago.

Its the main engine computer beside the battery..

Customer: replied 1 year ago.
What do you touch on the PCM to test it for 12V?
Customer: replied 1 year ago.
I mean where on it?
Expert:  -Brad- replied 1 year ago.

Did you see the wiring diagram? You need to check Red/Orange(pin 29), Yellow(Pin30), Pink/White(Pin12)..

Customer: replied 1 year ago.
This is the wife. Hi. They are out there working. They have to take off the top of the fuse panal to see the wiring. Correct?
Expert:  -Brad- replied 1 year ago.

No just disconnect the PCM connectors..

Customer: replied 1 year ago.
OK, he said it doesn't have a bracket like shown in your diagram, so he is taking the whole thing up to get at it.
Expert:  -Brad- replied 1 year ago.

Just need to disconnect the two connectors and then locate the pins and check for voltage..

Customer: replied 1 year ago.
Does the key have to be on when you test the 3 pins?
Expert:  -Brad- replied 1 year ago.

Yes

Customer: replied 1 year ago.
OK.
Customer: replied 1 year ago.
But, can the PCM be disconnected when we test the pin holes? Because the only way we could test it was to disconnect it because it pushes into the fuse panal.
Customer: replied 1 year ago.
we tested the pin holes with pins out and key off, and 30 came with 12 volts but 12 and 29 didnot register,, do we need to have the key on while pins are out or is it bad to turn key on while pins are out,, we have a half hour till dark and are outside
Expert:  -Brad- replied 1 year ago.

If 29 does not have 12 check fuse 17..

Customer: replied 1 year ago.
ok with the pcm unit pulled off and the holes exposed we retested the holes with same results,,, 30 12v,, 12 and 29 nothing,, with the key on this time
Customer: replied 1 year ago.
we are looking at the fuses in the box right next to battery,, which is fuse 17 they are not numbered,, is there another fuse box
Expert:  -Brad- replied 1 year ago.

I attached the layout for the fusebox..

Good Morning, Brad. We are back at it again. Can only do this car repair on the weekends. We never did resolve the problem. We located fuze 17, and it looks fine. We are wondering if the problem has something to do with the Security Safety System. I was researching on web and saw a few posts about problems with start after changing out the battery, (which we did a few weeks ago) because the security system needs to be reset. There is a description of a procedure where you turn the ignition as if to start and hold it while you press the UNLOCK and PANIC buttons on any remote at the same time and hold for 10 seconds. This supposedly resets the security system. Also you should know, that the drivers side door is not locking with the remote, and the gas gauge is not working. Since we only have the one key with remote, we are apprehensive about trying this, because we would have to use the same key for both operations, that of turning the ignition and activating the remote. What do you think? Is this just alot of hooha or should we try it? Or could it really screw up the computer? Sorry we didn't rate you, promise we will after this.
