Stalled out

I own 92 gp has a new found running problem. i can start it but it will only run for 10 or so minutes(won't even reach operating temp). then stall. I can't start it again until it is cold, at first i only had to wait 5 or 10 minutes now i have to wait 2 hours. just replaced icm. don't know what to do. no spark when it won't start. help ~shawn

try the ignition control module.take the icm to a parts store.most can test them.say auto zone. don't know the engine so can't tell you were icm is located.some testing you can do yourself if you have a meter and manual

I just replaced the icm with a brand new one. what are the chances i bought a faulty part? i'm going to check all the cylinders for spark write back in a little

replace the crankshaft position sensor

i have been a gm tech for 25yrs, done drivability for 15yrs, seen this many times, ckp sensor will fix it.

my check engine light isn't on, would the ckp sensor activate the ses light?

does ck eng light come on with key on eng off, does it start then, if it does, try tapping on the pcm while it is running and see if it dies, if it does, replace pcm.

im sorry ive been up for too long, can u rewrite that first sentence? does ck eng light come on with key on eng off, does it start then.. thank you so much for the help i really need my car. what are the chances that it is my ckp sensor? i just bought one on your advice, and i don't want to buy a pcm really. thank you

turn the key on, is ck eng light on, if it is, will it start? if it does, try tapping on pcm to see if it dies, if it does, repl pcm, if not, let it run untill it dies. when it dies, should have a ck eng light on, if not, turn off key for a few seconds then turn key back on, should have a ck eng light on. if no light, try a jumper(paper clip will work) on your aldl connector, jumper the 2 upper right pins, there will be a open space between them, when jumpered, should have a ck eng light flashing. should flash a code 12 three times and then flash any codes there might be, if you have no light when jumpered, probly pcm. if ck eng light works after it dies, probly a ckp sensor. by the way, what eng is this? 3.1,3.4?

Haven't tried the jumper yet, but the ck eng light is not on then first time and it will start. pcm is the computer right? and yes i have the almighty and trouble some 3.1. thank you so much for your help! i'll write more after i preform the tests
