How did this turn out for you? Did replacing the TCC Solenoid solve the problem you were having?
I have a 2004 Sunfire and I have had very similar problems that you described. My car usually starts on the first try most of the time, but on 3 different occasions in the past month it has not started for me. The time between failed start-ups has shortened. One night I tried for an hour to start it and it finally started. Ran well for 2 days and then the same thing happened; I stopped at gas station and it wouldn't start again. I had it towed, the dealership said it was the fuel pump and I paid way too much money to get a new fuel pump installed. That worked for about a day. Then one morning it wouldn't start again...and after 20 minutes, it started. The dealer couldn't find any problems and couldn't find any "computer codes." Just 2 days ago, my car wouldn't start and I finally got it to start, then I was going about 25 mph and it stalled once I applied the brakes, at about 0-2 mph. Everytime I try to start it and it won't start, it spins and tries to turn over, and sometimes catches, but only for a second, then turns off.
Does replacing the TCC Solenoid fix this problem?
Is it easy to troubleshoot this by unplugging the "square" plug on the transmission, like the "about.com Auto Repair" articles states?
Please...I need help with this...this is my only car.

Dude my daughter has a 2001 that is doing the same thing, she thought the trans was going out. I drove it and it runs fine, excellent power, no idle problems, but if you cruise with it at any speed then it starts missing and sometimes violently it usually drops 1000 RPM, does it in 4th or 3rd but not when I put it in neutral and hold rpms the same, or when I let off throttle completely. It only misses bad while steady cruising, I can wiggle the accelerator up and down a bit while cruising and it wont miss at all. The big prob for me is that no CEL or MIL is coming on. It has only 54,000 miles on it ! oh yeah its a 2001 Sunfire 4 Dr, 4spd auto with 2.2 OHV engine, no wonder I got it cheap. She is scared to drive it and doesnt have money to have shop fix it. So if you fixed your problem please clue me in, thanks. I usually NEVER have shop repair any vehicle of mine but I fear I may be becoming time and technically challenged . I am figuring a vacuum leak (although I can't hear one with hose, and starting fluid didnt change idle either), or sensor feedback resulting in a lean condition, but no MIL and only 53,000 miles? I appreciate all and any replies in advance ! Thank You ! OBD II....doesnt know jack!

I had a similar problem a few months ago with my 2004 Sunfire. I went to start my car on Saturday morning, and it wouldn't start. I would try to start it, it would spin, and start, but every time I let off of the key it would die. After taking it to the dealer (it was still under warranty), the dealer said that the wires on the ignition switch are very thin and apt to short. On my switch, the wires would only make contact while in the start position.
I don't know if this would help your car, but it's worth checking out.

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.
#69 of 306 GOOD GOD HELP ME!!!
Jun 13, 2007 (7:08 am)
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?!
