Can someone elaborate on this Hot start flooding stuff

Like the title says, can someone please elaborate. I think that my car might be going through this and I don't know what to do. I've never had my engine flood, so this is new to me. Basically the car won't start after its ran for about 30 minutes. I have to kick the clutch to the floor with the gas then pray it starts. Someone please help me.

Usually the problem with flooding happens after shutting down when the engine hasn't warmed up yet.

You probably have something else. Give some more details and hopefully somebody will be able to help you (what you drive, mods, recent behavior, etc.)

OTOH if prjct87rx7's tip works then your engine is flooding.

Ok. So its a 87 turboII with a street port. Everything else is basically stock for now. Its starts up from cold start at about 2-3 cranks. Then when I would run it for about 30 minutes, park, and try to start it again, it would be a pain to start. I think it is related to the hot start issue. Also, could living temperatures attribute to it? Its might not make any sense, but its been an average of about 100* here in Cali, and when I open the hood, the engine bay feels so hot. All my fluids are at level. Radiator, oil, etc.

Thumbs up The best day to day fix for this hot start issue

is first have your injectors back flushed and cleaned at RCEngineering to cure the leaky injector that is flooding the combustion chamber problem. http://www.rceng.com/

Quick fix, and perhaps a good thing to do anyway whether you get the injectors tuned or not, is to install Mazdatrix's H-Valve. This is the ultimate solution in my opinion.
