my 91 gta starts and then immediately cuts out. She just rolls and rolls unless i unplug the temperature sensor then she will start and then cut out.. im not sure the cause of this... its driving me insane.

 

In my experience, someone has to be a little insane to choose to play goal anyway. I've put on the pads and filled in when our "normal" goalies couldn't make it to a scrimmage, but pretty much spent life as defenseman as the usual role.

Anyway, it would be helpful to review the basics like fuel pressure, injector pulses (VATS), and ignition. It sounds like cranking is not a problem.

 

My first guess would be fuel delivery. Need to hook up a gauge on the fuel line fitting.

 

turns out.. its the oil pressure switch down by the oil filter... after changing the part out the car now runs and drives, not sure how long it will last but so far so good.

 

When you first turn the key on, do you hear the fuel pump running for a few seconds? That oil pressure switch is usually a backup only switch to run the pump in case the ECM circuit fails for some reason. Seems odd that it would cure the problem?
