Hey i got an 03 SS.
Starts great on cold start, After car is warmed up to normal temp car takes about 2 or three times to start.
I had this same problem on my 84 Monte Carlo and my 84 half ton, Is my starter getting to hot ? Should i get it wrapped in heat tape.Any body else have this problem??

 

I had the same symptoms.

Sounds like a fuel pressure regulator

 

Ya i did a lot of research and that's all i came up with was fuel pressure regulator.
Ill replace it and see if it wheel fix the problem

 

Unplug MAF and see if it starts. If it does, it might be your problem.

 

Could also be a clogged/clogging cat!

 

Sometimes it well start up and just die. Its like its not getting fuel.
I have to give it some gas most of the time to get it started once the car is at warmed temp, But car runs fine just need to figure out whats going on

 

Same thing happened to mine a while back, I got the fuel pressure regulator replaced and it fixed it.

 

I have the exact same problem with my 02 SS. Sometimes I get that rotton egg smell after the second or third try at keeping it running. Although I was thinking it was the Cat cause of the smell, the FPR makes more sense. Irratic idle and stalling after its been run and warmed but runs fine at cold starts and once it stays running. Gonna check that out this w/e.

Is this the right part i need on ebay. I have went to other part stores and they wont like 65 to 85 for new one. I found the same ones on ebay for way cheaper and warranty

 

It looks like it is. I would look on rockauto too if i were you. They have parts for cheap and they're reliable too
