Hot Start Issues on LT1

I have a hot start issue on my 94, it acts like it is flooded sometimes... I did install accel 30lb injectors and have heard these have issues sometimes. Is this the problem that they tend to have? Other than this, they have performed flawlessly.

I had a problem with a leaky injector once and it had a hard time starting after I shut it down hot. When it did catch it blew a cloud of white smoke that smelled like fuel.

What you can do if you have a fuel pressure gauge is to monitor your fuel pressure after you turn your engine off and see if it bleeds down. If it does you have ether a leaky injector or a bad check valve. However given the symptoms it would likely be an injector.

Could be ICM. Possible cause when the engine gets warm.
