I am having similar problems with my 2001 Sunfire with about 103,000 miles. I had taken it to firestone b/c the car died and wouldn't turn over at all. They told me it was that the entire fuel system was fried. That costabout $800 to fix. Worked okay for half a day. Started driving it again and the whole car would just turn itself off. Then I took it back in and had an oil change and a tune up and they replaced my relay switch for the iginition. This didn't fix the problem at all. Car is still riding and driving quite rough. Car will stall out when I have to drive the car a lot and always seems to happen in rush hour traffic. It happens at very low speeds. The ETS (Traction Button) will turn itself off and then then engine light will come on and next thing you know, the whole car is off. Turn it back on immediately and put it into gear and when I do that, the car violently jerks. Sometimes when trying to go, the car will hesistate and acts like it is going to stall. Newest problem just happened this past weekend. Pushed gas pedal all the way to the floor and the car stayed in 1st gear and wouldnt shift. Had to turn the car off and turn it back on and it again would violenty shift into gear. I have spent over $1100 bucks on the car in the past month and firestone can't seem to tell me what else is wrong b/c they say they can't find anything with all the computer testing they have done. The car turns itself off, so there must still be a problem. I am taking to a Ponitac dealership next week, if the car even last that long. Any ideas on what the problem might be??
#68 of 306 won't start...out of the blue...

have a 2002 Sunfire...right out of the blue this morning...it won't start...never happened before. It will turn over but then cuts out. Battery seems to be fine as lights turn on so it doesn't seem to be a battery problem. What could it be...alternator all of a sudden? Never had a problem before.

I bought a 1995 standard pontiac sunfire off this guy who wanted to get rid of it for a hundred bucks. he said it needed head gaskets on it. i thought hey good deal. i had head gaskets replaced on a toyota camry a few years ago and it was like 500 bucks. I in the end get a car for 600 bucks. Well it turns out that when the headgaskets go, it forces other things to go as well like the radiator and some other junk. I have it sitting in my parking lot. It runs, but I was told I wouldn't know for how long so i just have it there. I need to get it fixed, but does anyone have a main idea on how much it will cost me to get it fixed? Because of the headgaskets water leaks right into the oil. PLEASE HELP!!!!!! I NEED A CAR!!!!!!!!!!!!
#70 of 306 98 Sunfire - Random shuddering..
Jun 13, 2007 (4:55 pm)
I have a 1998 Sunfire 2.2L with 171,000km - all was well with the car until this week. I've started to notice a shudder like the car is missing. I'm having a hard time pin pointing when exactly the car does this since I've noticed it during acceleration and also while cruising at highway speed. It hasn't come close to stalling but keeps missing a beat seeming at random intervals. No engine warning lights at all & no overheating. Haven't noticed any starting issues either. I have noticed that when it's acting up and shuddering/missing I've noticed some loss in power when I put my foot down, it seems to temporarily resolve if i give it lots of gas and gets up into the higher RPM range.
I've been going down the most obvious path to see if I can rectify the problem - new plugs & wires, air filter, fuel injector cleaner. Although I can feel the difference in performance with these new parts and it idles much smoother, the underlying problem is still persisting. I've noticed the fuel filter has the under carrage oil protection gunk on it so I'd say it's been at least 5 years since it's been changed if at all. I made an attempt to change the fuel filter today but the quick release ring won't budge and probably needs a mechanic to cut it off and replace the filter intake elbow also.
I'm almost at the end of my short list of things I can diagnose/fix myself so I thought I'd post my problem before forking out the big bucks to a mechanic. $75 with no gaurentee it's even going to be fixed - who has that kind of money?!

Just reading up on problems with all GM cars caused by radiator and Dex cool coolant (orange stuff) blowing gaskets...leaking etc..
did you check to see what's in your radiator?
google Consumer Affairs GM Dexcool
hundreds of complaints..
one guy says he solved the problem:
M L of San Rafael CA (08/26/06) *WE'VE FIXED THE PROBLEM(S)!!
And while it's irritating to look back and see how much $$ I've needlessly thrown at my '92 K1500 Chevy Blazer, several radiators, head gasket, heater core, trans cooler lines, uptake gaskets, pretty much everything that has come into contact with cooling fluids has either corroded or slowly disintigrated. All due to what turns out to be a basic electrical design flaw at GM.
radiator guy hates Dexcool, suspects that perhaps it's the electrolisis that causes the Dexcool to turn to a jelly goop.
Says the higher the amp reading in the radiator, the more goopy Dexcool seems to be.
My story: The original radiator in my '92 Chevy lasted a good while (hint: older radiators had A LOT more copper in them). The trouble really all started and in a big way, after replacing the original radiator. I did pay the $500.00 for the new GM radiator. (hint: the newer made radiators have little to no copper in them. They are mostly aluminum and steel) Within a couple months, I started having to dump money into my K1500 Blazer, LOTS of it!
When radiator #3 started leaking, I got fed up with my mechanic, who kept saying, it's a high milage vehicle. I should expect this. Not thinking it was even slightly odd that everything seemed to be connected to the cooling system or somehow come into contact with it, even though nearly every repair seemed to require draining the radiator?? So, I looked for the oldest, greasiest, busiest, radiator shop in my area. First thing the guy did, after hearing the list of repairs I'd made, was to drop a probe in the radiator to check for a charge, in other words, electrolysis. An acceptable reading is .03 amps. I was running at .38 amps!! Turning the engine off it would only drop it to .27 amps.
So, he replaced leaking radiator #3, and rechecked it,.. .58 amps!! It went up! He shrugged and said, new one must have even less copper than the last one. I've seen a lot of these GM's with this crap going on. I've been doing this thing that seems to fix this problem. Then an off-duty local cop pulled in with his Blazer, newer than mine. We got to talking, he'd had most of the same problems and this radiator guy fixed it for him 3 years ago, and hadn't had a problem since.
Here's what my guy did...
#1 - Attached three, braided ground cables, randomly to the radiator and the block, and grounded them.
#2 - Then took a piece of copper pipeing aprox 3 long, with the same hollow as the heater-core hose, soddered a copper ground wire to the side of it. Midpoint on the hose running from the radiator to the heatercore, he spliced this small copper pipe into the line using hose clamps. Then using the ground wire he had soddered to it, grounded it to the engine block.
#3 - Drained and refilled the cooling system with DISTILLED water and GREEN coolant. Dexcool in his experance is CRAP, and I quote him. He did all this very quickly, then dropped the probe into the radiator and poof .02 amps! It cost me $100. He has me come in to recheck the amps once a month. And still 6 months later, .02 amps, and no new problems. I was averaging 1 problem per month, a leak here, a suspicious gasket there. Now nothing. So, it seems to me that there are really two problems. One affecting the other. A cooling system grounding problem, electrolysis resulting in corrosion and dissintigration of parts and gaskets. And then Dexcool which is unstable in an electrically charged enviroment and turns to goop. Maybe I'm wrong but my '92 K1500 Blazer now has 212K miles on the original engine
#72 of 306 96 Sunfire hard to start
Jul 09, 2007 (3:52 pm)
Just bought a 96 sunfire with the "big" (4.2?) motor. It won't start without giving it some, or alot of gas pedal. It has died at idle, with the AC off, but seems to keep running if the AC is on. I replaced the TPS, did as a friend suggested and disconnected the battery for a few minutes then reconnected and cycled the gas pedal. And I adjusted the throttle cable in a little. Daughter loves it other than it dying at stop lights. Any ideas?
#73 of 306 Easy starting 1996 Sunfire

Well, apparently disconnecting the battery cable for a few minutes did it! Also, driving for a little bit helped. I've driven it for two days now and it starts right up every time.
