#155 of 306 Re: 1997 Sunfire engine suddenly stops while driving [lexieb]
May 10, 2008 (6:56 pm)
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

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!

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.
#162 of 306 Find a good tech
Jul 22, 2008 (3:06 pm)
I live in ont canada. I have been a technician for about 5 years. I enjoy working with the electronic side of the auto. I have read many of the posts about sunfires and can't figure out why u guys can't get these problems delt with effiently. (Sry not verygood at spelling.) Mostly all of the problems found with sunfires are extremely common to all. If your techs are unable to locate these problems i sugest going somewhere else. For electronic problems i find that techs in there 20 to mid 30 are the best. Most old timers have no clue about modern technology. I have looked at about 200 sunfires for a no start condition and find 90% of the public neglect to change fuel filter. This causes undo stress on the fuel pump eventually it says goodnight.Rec fuel filter be changed once a year. When i bring a sunfire into my shop for a drivibility problem i can on average figure it out in under ten minutes. If u can find good qualified techs with good quality diagnostic tools they should also be able to do the same. If not come to my shop in canada.lol Ask your techs if they go on any courses, most good techs will go to them all, I know i do. You need to be constatly learning Hope that helps. ps u get what u pay for, if u don`t want to pay for the time to diagnose the car then what do u expect the tech to do.(sry just a little venting there.)
#163 of 306 2000 sunifre OBD port
Aug 10, 2008 (5:45 pm)
can't get the emissions done because obd has no power, or we just can't get a reading. I replaced the cig fuse and still no luck. Is there another fuse for the obd port or does anybody know what it could be. Thanks
#164 of 306 200 Sunfire stalling
Aug 10, 2008 (7:44 pm)
On my previous post I said that we also had tried many options to fix this stalling problem. We had even taken the car to a dealership garage. We spent $628.00 and it still stalled before the weekend so we took it back. They had it over a week and a half because they were swamped with other vehicles. (Only a few dealerships in a much growing town). We were mad and said we would pay for parts but no labor. Of course they would not go for that, gggrrr!!! but they did find the problem on our car. It was the ignition switch. They only charged us about a half hour labor even thou they said it took them an hour and a half. I couldn't argue because I have no idea how long it would take. I know it took my hubby/I about 5 hours to replace belts, hoses and a water pump so maybe it took them that long. LOL Anyhow, so far so good. *Knock on wood* LOL Sadly there may be several reasons for this stalling and we may all have to take each one of our cars individually until we hit on the one thing that gets each of our cars running again. For us it was the ignition switch. Yah! We got our Baby back.
