starting issues

[telly44444]

so when I drive my vette for a long period of time ( hour or so) when I shut it off and it sits for 20-30 mins sometimes when I go to start it back up it spudders, shakes and stinks and wont fully start.. Ill wait a few minutes , keep trying and the boom it starts. It sounds very unhealthy and I'm really concerned with the issue. My battery seems okay( 12.7 v at rest) and I changed the FOB battery today. think it might be fuel issue or air lock possibly?? it always starts good when its cold. It's really random and seems weird. car is a 2007 Z06 with 20k on it. it's also supercharged so if the stock fuel pump hasn't been changed I'm thinking that could be a source to the problem as I bought the car with all the mods done. I just got the car and this really sucks. any ideas or suggestions?

it has the e force supercharger #1572 B&B headers, x pipe with cats, and bullet mufflers. custom tune. car drives awesome when running , just has occasional issue to start.

Totally a guess here but I'm thinking the injectors are not sealing properly and flooding the engine after you turn it off?

it's in the air/ fuel somewhere. its going on the computer/ dyno soon to be looked at.

Check for codes first. Also do a fuel pressure test...but I'm thinking like Riley:
fuel leak and probably from the injectors.

my SCT programmer / scanner has thrown no codes.

car won't even do it now. started first try all day today. drove the piss out of it. Replaced fob battery. lol ... who knows.

Hahaha. Of course! Maybe all it needed was a good flogging?

If it happens again, I would ask Manny (Nasty98) if he would know the cause.
