Hello. Having starting issues with my 03 ss. Have tried several websites and no onme seems to have a clue. My car starts fine when cold however when she gets hot she does not. According to some EXPERTS advice I have changed just about everything that can be changed from a starter to an iac valve and just about everything in between including and not limited too fuel pressure reg. When it gets hot it takes at times 2 to 3 turns of the key to start, again only when she is hot. Can anyone help. None of the local shops around my area can figure this out. Dont want to have to take to a dealer. To dam expensive. HELP PLEASE

 

How close to your starter is the exhaust ? I had this problem on my 74 454 Monte and was able to rectify it by wrapping the pipe with steel insulation.

 

It could be a bad catalytic converter?

 

does it not try to start just crank over? or does it not crank when hot?
