is the pump not running? have you checked the inertia switch behind the passenger side kick panel?

[directtvman75]

no..im not getting enough volts to the pump due to bad ground when ecm is pluged back .in...i have eliminated the inertia switch a couple years ago..

for 95, pin 6 is for the vss, it wouldnt have anything to do with the fuel pump.

113- act sensor circuit open or reads -40*f
565- canister purge circuit failure
542-fuel pump secondary circuit failure.

what engine do you have and is it california emmisions or federal? it makes a little bit of a difference with the wiring diagrams in my chiltons manual.

i have a 302 non cali..i ran a hot wire straight to the pump worked for a few then died..i think my pump is bad..its only bout a year old..i know they can go bad anytime..

my chiltons manual shows that the canister purge valve and fuel pump relay use the same power circuit. i'd get a chiltons or haynes manual so you can trace the circuit. did you check to make sure the pcm is grounding the fuel pump relay?

yea i got ground to the fuel relay..got 12volts to each hot side of relay.im pretty sure i have a bad fuel pump
