the plenum fill up with gas

Bad/leaking injector and/or bad fuel pressure regulator. Put a gauge on the fuel rail and see what the pressure is. I think it should be about 35psi. A bad regulator might drive it to twice that.

that is what i was thinking and i will check the peseeure sand i will let you know what i find thanks

Oh fer christ's sake...

Pull the vacuum hose off the fuel pressure regulator, cycle the ignition on, is there gas leaking out?

=A0 =A0thanks

it fills up the plenum and it also leaked in the air box and the cruise unit with in a few seconds i am going to pull the plenum tommorrow and see what is what the injectors are very expensive to just throw parts at i am going to dig first to see if the gas coms out with the plenum off

Have you checked the pressure regulator to see if the diaphragm is perforated? As stated in the last post, just pull the vac line and cycle the fuel pump. The vac line should be DRY. If not, you need a regulator. A NOT UNCOMMON problem.

CHECK THIS FIRST before dissassembling ANYTHING.

i did find that the regulator is bad but i also found that i had one bad injector
