Why does my 2003 pontiac sunfire lose all power while driving


That can be the symptom of a bad Ignition Control Module, or also a bad crank position sensor. The ICM can be taken off and tested for free at any parts store. The crank sensor circuit can be tested on the car with a multi-meter. Also small motors (like a fuel pump motor) that are starting to fail can sometimes work until they get hot and then stop working until they cool down again.

Next time the car shuts down and won't restart, check for spark on a spark plug wire with the engine cranking over. If you have no spark, suspect the ignition control module or the crank position sensor. If you still have spark, but won't start, check if the fuel pump is putting gas up to the engine.

I have a 2003 Pontiac sunfire and today while driving the check engine light started flashing and the trac off light came on. the car has a burning smell to it .got home and touched converter with paper...


with the check engine light flashing you have a code set in the pcm that you need to have checked out as the light will only flash if there is a problem that can cause damage to the motor,like a convertor problem or overfuelling problem.if the light came on and not flash there is a code but not a possible engine damaging problem.that is the difference.either way you need to have it checked at a shop by a tech.the trac off light will come on some cars if a certain code is set in the pcm to get the driver to have things checked out that could cause damage,its just the way the manufacture has set things up.this does not mean there isn`t a possible problem with the traction control system.

You might want to have it checked to see if you have fuel pressure or see if there is spark going thru to your spark plug.If everything is ok it might be your timing belt needs replacing

2003 Pontiac Sunfire died on me, how/why?


If you hear a loud clank when you try to start it, but nothing turns, that is the starter trying to turn the engine, but the engine is locked up. If the timing chain/belt jumped, the engine would still spin.

Sometimes when your hazard light flasher goes bad this might be part of the problem. I have the same kind of car and i'm on my third one in two years. As for the other problems it almost sounds like theres a loose electrical harness inside the dashboard some where.............I Hope this information was helpful Thank You For Using Fixya.com!
