Are your electric fans coming on? also try putting on your AC this activates the secondary fan motor. This may just be a fuse issue. look up the lower and upper blower motor fuses and check them. that is a water temp sensor just below the large hose off the top of the radiator located just below where that hose meet the engine. This tells the computer when to turn on and off the electric fans by the water temp.

Is there a heat shield on the starter

I don't think there is a heat shield on the starter but, I wouldn't think that would be you're problem. I would try changing the ignition module. It's on the engine block, drivers side, I think. Usually when they are going bad they will shut off engine when they get hot. It won't crank until it cools off. After it cools engine will crank and run good until it gets hot again. Good Luck.

Got 1989 Grand Am with 2.5 engine Am having problem with it I have changed ingition module coil packs fuel pump filter plug wires even put a remanufatured computer in it . the problem I haveing with it is...

Sounds like the injector windings are opening up. I hate to have you toss more money at this thing so lets do this. Plug a noid light into the injector plug when you have the no start problem.. If the noid light flashes. I'm correct. If it don't, I'm wrong and we need to look at the crank sensor...Good luck. If this was help please leave feedback.

I think you may be on the right track. If the timing is too far advanced, the engine can overheat. The computer uses the crank sensor input to time the engine. Let us know if it still over heats with the new crank sensor in.

OK i have a 1999 gmc Yukon i just changed the fuel pump spark plugs ing coil control module wires but she still wont crank she starts then shuts off whats wrong HEPL ME PLZ

I suppose that you mean it starts but doesn't continue to run. And if you try to start it right away it'll just crank. The fuel pump is on in crank but not in run ( maybe ). Find the fuel pump relay in the underhood fuse relay panel and use a test light to cheak the pins for power and ground. First with the test light hooked to a good ground, check to see if it works first ( touch the battery positive ) then touch all the pins of the relay ( removed ) One should be hot all the time ( if not the fuel pump fuse is blown) another should be hot with the key on. one of the others will be hot only in crank ( this is the fuel pump) The last other is ground with the engine running after started. The one thats hot in crank put power to it with a jumper wire and start the engine ( it'll run ) the fuel pump also gets turned on by the oil pressure switch and the fuel pump fuse is blown it'll also not run the engine. But it'll run right after it's cranked and quit
