Having troubles getting the fuel pump to cycle after turning the key to on position, here is what i have done so far, FYI, Just replaced the stock fuel pump with a255 lph Walbro. Tried turning the key to on position got nothing, i do get spark and the ignition dash lights up. I checked all the fuseable links and i replaced the relay under the seat. I have reset and checked the inertia sensor in the back. So im running out of tricks in my bag, Also when i put a volt meter on the relay, control path gets 3 volts, then i read 3 volts at the inertiasensor, but no voltage at the fuel pump wire atthe pump. Nowwhen i check the power path on the relay iget 12 volts at the Orange and blue wire before the relay andnothing after. I have not checked the eec relay, and i have tried jumpering the eec test lead with no luck either im not doing that right or its not working. Any help would be appreciated , thanks

you might have a bad inertia sensor, check the voltage right after the sensor. see what you get. hope i helped!

FYI im reading 3 volts on both sides of the inertia sensor, so im thinking the sensor is good but i think i should be reading 12 volts?

yeh thats a problem upstream the wiring.
