I have a 1993 grand am SE and its nothing but a piece of junk I will never buy another. My car is in the shop every other day.
WAY tooo many problems I am very disappointed with it.

1990 Grand Am 2.5L here. I had the same problem as all of you. Engine stalls when the engine is warm with no warning. Once it stalls, it'll turn over all day long-but only after you let it cool down will it start right up again. This is the CRANKSHAFT POSITION SENSOR, a little plastic sensor that GM decided would be just fine inside the 2000+ degree engine block.
Good luck, Grand Am owners!!

I have a 91 with the 2.5. I had the same problem. If I went above 70 mph or needed a quick burst of speed it would chug a bit and die on me. I sat on a few interstates for this one. It turned out the be the crankshaft position sensor, so that seems like the logical choice for anyone having this problem. Later when the weather started getting warmer if the car sat running in a drive-thru and got to about 200 degrees the fan would kick on, but I'd shut it off, go inside a store and it wouldn't even crank. Almost like when the starter locks up. Once again when you waited 10 minutes it starts right up... more annoying than anything. My father is a mechanic and we have both racked our brains with this one. It's not the starter, it's not the ignition module because all electrical comes on when you turn the key, and it's not the neutral switch. By the way, all the neutral switch is, is just a crude metal contact that hits a sensor when it's fully in park and can expand when hot making it not hit the sensor and not start. So finally we just ran a simple electrical from a push button in the cabin to the starter, so if it ever doesn't start I turn the key on and kit the button, pretty much shorting the starter to crank. The funny thing, we seemed to fix the problem while doing this because I haven't had to use it yet in 2 months when it did not wanna start every other day. So your guys guesses are as good as mine.

I bought a 91 Pontiac grand am about 8 months ago. It ran fine four 7 months now it will cut off after driving it for 45 min. when you come to a stop, but it will start right back up. then when you put in in drive it will die again. So I have to start it and then give it a lot of gas then put it in drive to take back off do you know what this is.
