I have an 03 coupe.

Someone hit my car and left. Theres a bump around my left rear wheel.

So I brought to the garage to fix it.

3 days later, I came to pick it up. The body looks fine.

But everything in the car is reset (radio, etc). I guess they might have disconnected the batteries.

Now sometimes when i start the car, the engine start then stop ...

 

it might be your MAF... sometimes as in when your engine is hot?

my MAF was doing that and car would cold start fine.. after it warmed up i would have to blip the throttle right after i start it to keep it running.

 

We need more detail.

When you say that it doesn't start.... does it crank over when you turn the key but just doesn't fire? Does it fire up a little and then stall out? Does the starter turn but the engine doesn't make any noises as if it's being turned by the starter(you'd hear just a little electric spinning noise and perhaps some clicking, but no engine chugging sound).

Is there gas in the car?

 

make sure the wires that connect to the battery is connected properly...sometimes the ppl ther forget to tighten it...thatz what happend to my old car...it kept stoppin when i was driving...and finally figured out that they didnt tight the wires properly to the battery...

 

I turn the key, it starts, then a second after it stop.

 

yeah it does does it when the engine is hot ...

 

Its exactly what you say. I start the car in cold, it starts fine.

But when its warmed, I had to press on the gas to start the car or else its stops.

How did you fixed it? Bring it in to the dealer?

I went to the body shop that fix my car, they say its not there problem.... That they didn't touch anything since it's only body work.

 

Help? looks like its a MAF problem, should I bring it to the dealer?
