I have searched the heck out of this and haven’t found a resolution...
Swapping an LS1 into my 72 Camaro. PSI stand alone harness and MSD inline fuel pump with C5 regulator.
I cannot get the engine to start and there is no pressure in the rail per the Schrader valve. When I pull the hose off at the rail, plenty of fuel comes out when I turn the key and the fuel pump primes. As soon as I reattach the fuel hose into the rail, NOTHING. I pulled the rail and cleaned it out with compressed air and fuel injector cleaner getting a little gunk out. I also bought a new $130 MSD pump to ensure the original one wasn’t a lemon brand new out of the box.
I dont know what else to trouble shoot. All that is really left is the pressure pulse dampener being clogged/ faulty or the rails just being faulty which I don’t even know if is even possible.
Please help!
Thanks, Jim
