#152 of 306 Stalling Sunfire
Apr 24, 2008 (12:08 pm)
I have a 1997 Pontiac Sunfire and last summer when stopping in traffic my car stalled. It started right up again than stalled whenever i had to come to a stop. It was fine all winter but last week it was warm and i was idling at a red light. When I went to accelerate it stalled. It did this 3 times on my way home everytime I had to stop.
Could this be the fuel pump?
Thanks so much

Hi there, my car has a similar problem, but I haven't had the fuel pump changed. What I learned about the fuel pump though is not to have my fuel go below half a tank. Does your car also have a difficulty going uphill?
Try to see if your car would have a hard time going uphill, and do take note of when your car stalls (whether at full tank, half a tank of gas, a quarter of gas). My car still runs and doesn't stall nowadays, but I make sure I always have a full tank or close to a full tank of gas. I also do not turn on the AC, as the car cannot take load and eventually stalls. My mechanic has replaced the car's module, plugs, wires, coils, sensor, and fuel filter. I think it needs an EGR valve and possibly a new fuel pump.
Hope that helps. Anyway, if you've identified the real culprit for your car stalling, do share. Also include which parts you've changed to solve the stalling problem and how much it cost you.

My 2001 Pontiac Sunfire has the identical symptoms. I have change the whole fuel and ignition systems. I've even exchanged the entire exhaust system. It ran good for two weeks. I just left it at the Wal-Mart parking lot knowing that nobody can possibly steal it. I agree with an earlier e-mail traffic stating that the Transmission Control Solenoid in the transaxle may be defective. I have worked with earlier Sunfires, Cavaliers and Celebritys that also have this device and it is a very unknown item even to the local mechanics (or I think so $$), however; it is never mentioned in commercial repair manuals or at dealers (they are mum $$). And these symptoms are indicative to all GM front wheel drive vehicles. The Transmission Control Solenoid activates at 45 mph (your overdrive), however; if stuck, it may fool the PCM it is going at that speed even though you are going 20 mph and cause the engine to become flooded by fuel, hence the stall and leaking fuel injector symptom and starting two hours later. Please, look at part number TCS1 at Autozone. I'm replacing mine tomorrow. It costs approximately $26.99. Commercial repair manuals do not mention this item (I wonder why?$$) Unbolt the the rear transmission pan (not the bottom pan) located on the driver's side of the transmission (approximately 10 bolts) and you will see the Transmission Control Solenoid smiling at you. For those of you that have felt the frustration and loss of money; General Motors, the secret is OUT!!!

#158 of 306 My 97 won't start
Jul 03, 2008 (10:24 am)
Hey there can anyone help me with this situation. I own a 1997 and I replaced the spark plugs on it, fuel filter, changed oil, ignition switch and a starter. And it still won't start. I hope someone understand what I'm talking about, but the theft system light won't go off and the little orange triangle above the gears on the dash well if it is not lit up the car won't start. What does anyone know about that? Please HELP!!! Me and my father also rented a diagnostic thing from auto zone and it read passed no codes need. Well then what is the problem!
#159 of 306 Yeah!, I don't feel alone on this problem

I am so glad I discovered this site. My Husband/I were going nuts trying to find out why our 2000 Sunfire (Sunny) was stalling. We just spent $628.00 for Injector kit, BG throttle body service at a Pontiac dealer because we thought maybe they would have some idea since they work on them all the time. They also said our water pump was leaking so after quoting us ANOTHER price of $700.00 plus (we did it ourselves Saturday). We also have done a full tune-up with the works of spark plugs, wires, ect. Battery is fine. Alternator is fine. Fuel pump replaced 2 years ago. We are tottally stumped but are taking Sunny back to that dealer because they DID NOT fix the stalling. We refuse to pay for any more labor. They said they diagnosed it and that was the problem. I never got any recall notices either. GGGRR!!! We had no problems with Sunny until now. Its freaky that so many of us are having this stalling problem. Especially since it is all different years. My Husband/I have been baking in this Volcanic Texas Sun working on Sunny. Pontiac needs to look into this and why so many at this time? Very odd.
