What would cause a 1993 Pontiac Grand Am to quit running while driving it then not start back up for about 15 to 20 minutes?

Answer 1

Check your lock-up solenoid. It is located in the transmission side pan. It will become stuck when the transmission becomes hot, causing the car to want to stall when coming to a stop and shutting off the car when put into drive while it is hot. I had the same problem and it ended up being the fuel pump. When the fuel pump is going out it will get hot then shut off and that will cause your car to shut off. then 10 to 15 min. later the fuel pump will cool off and the car will start. Not trying to step on your answer. If you are not doing a lot of highway driving Disconnect the trans switch it is a four pronged push in located at the front of the trans. It might lower your fuel economy just slighty but it will solve the stalling. I replaced the tranny in my 92 because of this and four months later same problem that was 2700.00 I could have spent on something else I have be running for over 8 months like this and I drive about 1600 miles a week both highway and city. If the vehicle dies immediately when you shift to D...the problem lies in a stuck TCC solinoid. This usaully happens once the car warms up & has a 125C Transmission. Well most of the time, when your car gets to hot it automatically shuts down the engine to keep the alluminum head from melting, when it cools off it will start right back up. could be the coil It is most likely the crank sensor, this happened to me. Had the same problem, I replaced everything from the fuel pump, fuel filter, IAC valve, throttle body, and it ended up being the Crankshaft Position Sensor. I had the exact thing happen to me on a 1993 Pontiac Grand Am. I spent about 1200 replacing parts on it. When at last I figured out it was the Crank Shaft sensor. Then it would drive for a while and die. That ended up being a seloid in the transmission. fuel pump. my 2002 grand am has already had this replaced. not to hard to do. drop the fuel tank and it is self explanitory.
