I have a 92 that has me stumped. I left work one day and as I pulled into the street, it died as if I turned off the key. The obvious went through my head. Ignition switch, coil pack, icm, etc. I have another car I'm restoring so I robbed some parts and had the icm tested. This car runs so I know they're good. None of these were the problem. I checked the fuel pressure and I'm getting 42psi and I've got fire at the plugs so I'm not getting fuel into the cylinders. It's like my fuel injectors just shut off. Do they have a fuse or something? I plugged the FI relay into the fuel pump and the pump came on so the relay seems ok. When I turn on the key, the fuel pump does not cycle for 3 or so seconds. Instead, it just stays running and the "check engine" light glows dim.
I dropped the tank to see if there was anything that might be obviously wrong. I changed the F/P strainer while I was in there thinking maybe that was clogged up. No luck. The only other thing that comes to mind is the PCM. I've never heard of one going out but I suppose it's possible. I've checked everything I can think of. If anyone has some insight on this, I am all ears (well, eyes). My wife is getting tired of taking me to work everyday. I'm about to say screw it and go put my order in for the 2011 GT. That would fix it for sure.
