1988 Chevy Corsica Engine stalls

No check engine light until it stalls. Fuel pressure is good. Pulled the ignition module yesterday, had it and the coils tested, all good. Replaced the Crankshaft position sensor, engine started, but because of an oil leak fron the oil filter cover gasket, I had to shut it down and replace the gasket. Gasket on order for today. Had to pull oil filter & cover to remove starter to access bolts for coil pack.

Will do.

Still does the same thing. I did notice that it loses throttle when it tries to die. When it starts back up, there is no throttle. AAAhhhhhhh! I feel better now. ;-)

When I hit the throttle, there is no change at all. Is there a way to check codes without a reader? Seems I read somewhere that you use a jumper and read the flashes. Another idea I had, one of many, was that if the crankshaft position sensor wiring had a short in it, it may cause this condition also. I don't know if it's possible to bypass the sensor to see if that may be the cause. Aren't electrical issues fun? :-)

I know where that is at. What about a fuel pump relay failing? Where is it located? A new one pretty cheap. I found four relays on the firewall, but none of them look like the fuel pump relay on autozone website. I'll keep looking though. Thanks for you time, I really appreciate it. I am one of the many unemployed, but will try to donate something when I can.

Well all 4 of the relays seem to be doing what they are designed to do. Fuel pressure is good. I am thinking that it's either a coil breaking down or the spark control module failing. The reason I am thinking that is because there are no codes other than code 12, even though they tested good on a machine. The owner wants to replace them. It seems that I am just throwing parts at this thing, but it's the direction I am leading to. The engine will run when it's cold, but once it gets a little warm it acts up, hence the coil or spark control module breaking down. Before I buy new parts, a friend had the same car and is going to let me play swap a part. I'll let you know how that goes. Oh and by the way, what you are telling me is helping more than you think. Thanks!

Replaced coil pack.
Replaced spark control module
Replaced computer.
Replaced map sensor.
Checked Fuel pump relay.
Checked voltage at TPS
Checked fuel system.

After replacing computer, engine started & ran fine for about 7 - 8 minutes. We shut it down to do some reassembyl. Went to start it, same problem. No starting. So how does that cash for clunkers program work? :-)

AAAAAAAAAAAAAHHHHHHHHHHHHHHHHHHH

I think the CFC program is a bunch of crap and a way for the commies to get good ol' American stell off the roads. Those of course would be good old toys like the one I have. I wonder how many 62 Ford F100 unibody trucks have been crushed. I agree that there should be a program that gives people a chance to buy the cars at a really good price. It'll probably never happen though. To get back to this car now that I am done ranting.

When the car was towed to me, it would start, run for a short while then the engine would die. It may or may not restart. We checked & replaced the coil pack, spark control module, and computer with known good parts. We checked the 4 relays that are on the firewall, the one on the drivers side is for the fuel pump. When you turn the key on, the fuel pump runs until it pressurizes the system, then the relay shuts the pump off. We even swapped relays around in an attempt to find a bad one. No bad one found. We checked the fuel system and replaced the fuel filter as a just in case. We checked the ignition switch for correct operation and saw no problems. The weird thing is that after we installed the computer, the engine started & ran good for 10 minutes or so. I shut it off so we could reinstall the fan that was removed to replace the coils & spark module. After everything was reinstalled, we went to start it and it wouldn't start. :-( It seems like it wants to start, but just won't quite get there. I was thinking of something in the fuel tank, like a piece of plastic that would get drawn to the suction. But why would it start & run for 10 or so minutes then not restart? It's like there was a relay that kicks out as soon as the engine starts. I think it's something so simple, I just can't see it. Thanks for any input you can provide.

I didn't notice you complaining at all. :-) I wonder how many rice burners are being crushed?
I am trying to make up a fuel pressure guage as I am typing. I am still stumped on why it ran so well for the time that it did, and now it won't start. I put a line on the pressure port on the fuel rail and during starting, there was pleanty of volume. I know that doesn't mean pressure though. I'll probably start again in the morning. 10 hours with no answer is starting to wear on me and my friend that's helping me.

Besides all the other stuff.
Fuel pressure 40 -45 PSI and holds system pressure for over 3 hours. Checked injectors, injectors getting power and test light is flashing. Checked EGR valve for being stuck, operating as designed. Checked throttle body, operating as designed. Checked idle circuit, no problems found. I am stumped! :-?

The reason I am asking is because I had to drop the starter down the first time I pulled the coil pack. The engine statered after the coil pack was installed, but I am in the guessing mode now. I pulled the fan again and verified that the coil pack was plugged in completely and it was. The starter wiring is in the starting circuit and if there was a bad connection, it would turn the starter, but when the solenoid disengages, maybe that's when I am losing the fire. No codes. I am stumped! :-?[/Quote:c23cb44e80]
