I have been fighting with this issue for some time now and haven't driven the car in months.
Car starts, runs, shuts off almost instantly, if I start it and constantly work the throttle it will run, but very rough.
its a 3.8l fuel injected engine.
Here is a list of things I have tested/replaced:
Plugs
wires
crank sensor
cam sensor
MAF
coil pack
ignition module
oil pressure sender
ECM
Fuel pressure is good and flowing, have powered fuel pump directly.
TPS, tested, read ok.
EGR, cleaned, no leaks.
also, I have gone though the GM 87-88 3800 stall diagnostics manual from gm.
so, whats left?
