Warm engine starting issue

[c_artgo]

I have a 93 that has been modified with head work, ignition,exhast headers, 30lb injectors, 58mm throttle body that runs fantastic[ over 360 hp at wheels. the only problem that I can't figure out is every once in a while when the engine is warm and has set for a few minutes the engine cranks but won't start unless I just lightly touch the gas pedal. The injectors aren't leaking and everything seems to be OK. Anyone have any ideas, not a critical problem just anoying.

HI there,

Well, you could have a fuel pressure bleed down, the injectors could be shorted out when they get hot or the injectors could be leaking.

Or, you could always have an optispark sensor issue.

I would start with taking injector resistance when hot.

What is your fuel pressure sitting at and how fast does it bleed down????

Allthebest, c4c5
