I have this annoying problem. I am wondering if other Camaro/Firebird/Trans Am owner have the same thing...

Cold start... fires right up, I barely have to bump the key and she comes to life.

Hot start... say the engine is all warmed up after a run, situation " Let the car sit for 5 minutes or less" .. starts right up, again I barely have to bump the starter...

Hot start.... different situation, the engine is all warmed up " Let the car sit for more than 5 minutes and she is cranky to start, will have to spin her over and over before she catches, strong smell of unburnt gas (most likely due to the fact that she has to crank over so many times)

I was thinking that since the gas lines on the 87 5.7 L run very close to the manifolf that after sitting for a longer time it would heat the gas in the line and vapor lock me....I am not sure if the 88-92 5.7L's have the gas lines ran this way or not (pretty sure they don't)

Anybody have this problem? Anyone know what the cause/cure could be??

 

Mine and my cousin's TA's had a starting problem similar to yours. Cold start...fine....hot start...not fine. Turns out that on the 3rd gens sometimes you need to install a heat shield for the starter. The starter gets too hot. Hope that helps....
