![]() Dark,
Disregard my last, I've been drinking again! I will absolutely investigate the hose while I've got the tank down. Cheers

![]() Update:
Back at it again...I'm not showing any power getting to the fuel pump wires at the tank. Which wire is the hot one at the relay under the seat? I'm going to check there for 12v then move on. The tank is off and the pump is hanging out for troubleshooting. I'm not going to bed until I figure this out tonight. No beer either so I had better figure this out.

![]() The red/black wire to the relay under the driver's seat shows 11.8 vdc. I'd like to test the output, but don't know which one to pierce.
I have 4 of these advance auto parts relays, can they all be bad? Does anyone have the wiring diagram? I'm thinking the relay itself, because there is no power on the red wire at the fuel pump. Reminder: The car was idling fine in my driveway when it just stopped. So, I doubt it was the inertia switch crapping out. thanks...

![]() I've got 12v at the inertia switch red wire too.
should the red black have 12v also back to the fuel pump relay? I can feel the fp relay actuate under the seat when the keys are turned so it seems to be working. It's still dead at the fuel pump connector...hmmm

![]() The relay can still turn on without supplying power to the pump.I have a diagram that helped me before,follow the black/orange wire back to the blue wire with fuseible link at the starter solenoid.This is the power wire to the computer that supplys the relay to power the pump,hope you can make some sense of that,lol.

![]() Okay,
Uh, how do you check a fusable link? continuity on both sides? That matches my diagram too, I'll check it next. Thanks, John
