SOLVED:

it was my aftermarket immobilizer. It was cutting out the signal when it got warm and therefore shutting off the engine. Took it out and the car is running well.

I changed the ignition switch (yes, removed the stereo and gauges to get at it). Didn't fix the problem. So I replaced also the ignition key lock cylinder but also no fix. I disconnected and...

I used a multimeter and found that there is no voltage coming to the ignition control module. So maybe it is the CKP sensor.

checking fuel pressure right now

the other thing I haven't done yet is the 7x CKP (crank position) sensor. That's the one on the back of the engine. Is that a possibility as well?

now it will only start and run for about 3-4 seconds. When I press the gas pedal to try to keep it running, it backfires a bunch of times and then stalls.

I think I've done almost everything that could go with spark or electricity. So I suppose I'll start with the fuel side now. I'm going to check fuel pressure.

the problem has worsened - first it...

okay - I was planning on checking and potentially replacing the ignition coils (there's three of them, I believe). I will test the ICM as well. My thinking is that if only one of the three coils is...

ckp sensor or coil pack bad with no SES?

hi all - I'm having stalling issues and according to scans it looks like there are crazy fluctuations in engine ignition timing. This causes random stalling while driving once the car has warmed up....

I did a full VE tune (without disconnecting the MAF). Then I topped that with a MAF tune. Things are looking very good now. The trims are as much in line as I had them before installing the...

okay - that makes sense now. This why you want fuel trims to 'lock in' at 0 during PE. But when a tune isn't perfect yet, and LTFT locks in at, say, 0.78, does that mean that the pcm is constantly...
