    Supercharger install = no start; any advice?

    Hey guys just finished up my MZ3 Dinan ISR-3 supercharger install. But it's not starting. -- I'm going to go down the list; spark, gas, air, etc. But is there anything I should do before the first start up? Like prime oil lines to the suoercharger or anything like that?

    I hope this is an easy problem to track down because I have touched every bolt on the damn car. Re-wired in HFL meter, wired in Keen bell BAP, wired in two boost switches in the fuse box, installed new injectors, installed D10 intake chip, and aligned new DME...

    All I can say is no trouble codes have been triggered. lol

    Fuel pump runs when you turn the key on? +12v at injector and coil connectors with key on? Coil ground wire attached to front of head? If you have a 12v test light hook it up to both the injector and coil connectors and crank it over to see if the dome is pulsing them.

    Thanks Someguy2800, looks like no fuel pressure, no fuel to the rails. I have it tracked to either a faulty Ken Bell boost-a-pump, or I wired it in incorrectly. But the wiring is so basic dont see how that could be wrong. (Power going in, none coming out, that keeps power from activating the fuel pump relay).

    I'll call them tomorrow.
