bled injectors don't know fuel pressure but the lp is pushing
Should I get flow at the injectors without the engine running just the lp?
can something break on the ip to let fuel go right thru?
there are no other odd noises

You should get fuel to the injection pump by 'bumping' the starter.
If no fuel is flowing at the intake banjo bolt after 5 or 6 cycles of bumping the starter, your lift pump is probably toast.
If you have fuel at the intake, and have slightly backed off the fittings on a couple of the injector tubes, and see no fuel, you could have a bad injection pump relay,or a bad pump.


The fuel pressure at the injectors should be in the thousands of PSI range so don't have hands, face, eyes etc near that area when cranking with the injector lines loose.

sounds like the ip then. Its just a small flow while cranking with the lines cracked. It doesn't spray.

thanks for the speedy comeback.

just finished putting a holley blue in with vulcans 1/2" fuel line kit. I am definately getting fuel to the ip! I bled the injectors again and still no crank. Is there anything else other than the ip? All the fuses are good.


thanks,

So you are getting good flow to the injectors?
