This is one thats kinda got me stumped, so I wanted to see if anyone out there could offer up some insight. I've had a problem lately, just in the last few days, with my 91 dieing right after I start it up. Once it happened twice in a row when it started it up and finally the thrid time I had to sit there and rev the engine for a minute or two to stop it from dieing. The other times it has started up and right after I've started moving or pulled out of the parking space it will idle real low (like 600, maybe 750rpm) and then die. The engine light comes on and I have to put it in park and restart it. Its happened to me when I'm in park and in drive if that helps. I don't actually have a scanner so I don't know the code its throwing(anyone know a good place for obd1 scanners by the way).
So, I was searching throught the forums earlier and someone had a sorta similar problem that was fuel pump related, so that might be a good place to start since it only seems to happen while I'm trying or right after I crank it(except there was one time last year that it randomly did it that was after I had driven a few miles).
The plugs, wires, and battery are 1 year old. I did the delco ICM swap a little after that, which I'm leaning towards maybe I got a bad one. The most recent thing I had done was the upper intake gasket replaced and all the intake cleaned out.....which incedentally, its runs sooooo much smoother after that.....but, seems to die a whole lot easier
But like I said, this ones kinda stumped me a little bit, so if anyone has any good starting points I'd love to hear them.
Thanks again everybody.
