Been off the forums for a while, but here's the situation:
'97, currently will not fire but will crank over. The theft light is blinking regularly as soon as the ignition is turned to run, it goes off in about 45sec to a minute with no coded blinks.
I just replaced the fuel pump since I thought at first that was the issue. It fired up and then died on me as I was trying to leave work a while back. Thought it was the fuel pump because I was not hearing the pump run when I first turned it on. I'm not sure if it was blinking the theft light at that time. It would crank over but not fire.
I had it towed home, it sat while I tracked down parts to replace the fuel pump, and then on impulse I tried to start it and it fired right up. It died a few minutes later, would not fire over to restart, but cranked just fine. This is the point I first noticed the theft light.
Since I was not hearing the fuel pump, I replaced it with the new pump. Got everything buttoned back up, and turned it to run and back off about 10 times without starting, to get the pump primed. I could hear the pump running during this. Started it up, it ran for about 5-10 seconds, then died. Once again, no sound of the pump priming when I first turn it to run, even after it has sat for a long time.
Additional tests I've done:
-It will not start in neutral.
-I have tried unhooking and re-connecting the battery multiple times, with plenty of time unhooked to reset computer codes. No improvement.
-Sometimes it will lock out the shifter, sometimes not.
-I have tried various tilt positions for the steering wheel to see if something is losing contact on the sensor ring for the PATS system at the ignition lock, no change.
-The fuel pump fuse in the underhood master power distribution fuse box thingy (can't remember the acronym) is fine.
-It WILL fire over with starter fluid sprayed in the flex hose ahead of the Throttle Body.
My research is pointing to a PATS issue, which is a real problem for me since I am down to only 1 key after the fob, master key, and 1 spare were lost when I had it at a body shop.
Immediate questions for those more knowledgeable than me:
Will the PATS system disable the fuel pump on a '97?
Are there any other fuses or wiring I should check to see if it really is a fuel pump powering issue?
If it is a PATS issue, shouldn't it blink a code before the theft light goes off?
Any recommendations? Anyone have a complete '97 PATS module and matching ECU with at least 2 keys that they are looking to sell? I'm about ready to throw in the towel on this one. I'm sure if I take it to the stealership they will charge me a huge fortune and not get it fixed.
Much appreciation in advance for any ideas / help.
Thanks,
