So i got in a new cas and ecu today, and i went and plugged it it. Cranked, no go. So i checked for spark, spark is good. Checked for injector pulse with a noid light, good as well. Decided to play around with the timing, still nothing. Pulled my feed line going into the fuel pressure regulator, and check for fuel pressure, filled a beer bottle in about a second, so thats good. Pulled a spark plug and noticed it was dry...should be wet with fuel from all the cranking. Sprayed some carb clean in the intake manifold, and she rumbled for a second. Now my question is, can a fuel pressure regulator go bad and prevent fuel from entering the fuel rail, or do i have 6 bad injectors... Its a series 1 engine, with greddy intake manifold, maybe it matters.... Ive been batteling a no start for over a year now, and im SOOOO close, please help...

Is your wiring done right, and good grounds. Fuel pump working?

everything is working as far as i can tell, its getting spark, and signal to give fuel, its just not getting the fuel....

Sounds like you got your lines backwards, since you said can the regulator stop it from getting fuel, regualtor is supposed to be on the return side, yes it can stop it from getting fuel if your trying to pump fuel through it the wrong direction, make sure the one shooting fuel is on the other side of the rail
