:( bad injectors?

when you turn off your engine and the injecotr just drip does that mean its busted? or is it just stuck open (i wish :P). lets just say its a pretty constent flow of gas to where the throttle body is flooded about a half of and inch and riseing intill i let out the pressure though the gas tank cap, i was a little bit hard on it because i am testing in right now and tring to configure the fp but still thats really sucks now i cant get the catback now o well stupid holley injectors. o and i have a holley unit.

my engine is really flooded! its still going, at this pace my engine is going to be under fuel in a sec , should i just keep the cap loose to let out the pressure? how big of a fire hazzard is that? anyways where is a good place to get injectors, some that do not brake that can last over 700 miles

Yeah, just to be safe. The excess gas is going to dilude the oil, that's bad mmmmmkay.

well i have put new oil in it and its doing kinda good, the injectors that got stuck is spraying good but its not quit as direct of a shot, some of it hits the very edge of the tbi and i have heard that that is a sign of a bad fuel injector, i am prolly going to toss them anyways becasue i really dont want to take the chance of doing that again because its not like take off the air cleaner every time i park to check to see if its overflowing, because if i try to start it and its at the rim of it gas is going to fly every where

Holley injectors are notorious for going bad. You can swap out an OEM/GM injector pod/tower onto your Holley base without too much trouble. I'd try that if Holley won't send you new injectors.

Well, if you made any mods you can probably forget about getting your money back. HOWEVER, if the injector isn't firing then you could have an issue with their quality control. HOWEVER HOWEVER, they can just come back and say because you were mucking around with the fuel pressure you are liable for any damage/problems. Holley injectors apparently don't do very well with increased pressures...

Better crack out your OEM stuff...
