Default 2001 zr2 pickup not starting

i just put a new fuel pump into a 2001 zr2 pickup that ran before i put the pump in. after i bolted the pump into the truck and hooked it all up the truck wont start. it has furl to the rail, and its got spark. the timing should be right. it has new cap rotor, plugs wires and fuel filter. the only thing i can think of is that is has no injector pulse. any help would be awesome, is there an enertia switch that would shut the fuel off? where are the relays for the injectors?

the inertia switch is a no thats a ford thing. as for the relay it should be in the under hood relay comparment. but that would only be half of it because, the computer controlls the pulse width and trim through the ground side in the comp. and as for the timeing even though it has a distributor you cant ajust the timeing the comp dose it, you can move the distrubutor but it dose nothing.

Ok... I had same problem because the NAPA store gave me the wrong pump. You need to check rail pressure... getting fuel is not enough, it needs to be at a 50(?) psi. You need to check spec., but pump assy I got from NAPA only put out about 35 psi and it wouldn't fire injector.

are you sure your not having a security issue? Try turning key to the run position, leave it there for more then ten minutes, then with out turn the key back to off try starting it (Do not turn key back to the off position, before trying to start or you will have to try over again).
