NO fuel pump...

You dont think the hose that goes on the pump could have cracked or came off do you?

Dark,
Thanks for asking. I've primed it over a dozen times, so my guess is that there'd be fuel somewhere on the chassis and ground if that was the case.
I think I'm going to go with another new 225lph bbk pump. It's an expensive way to troubleshoot. But I just installed a new Kirban FPR, so that's not it.
I'll naturallly check the lines when I drop the tank and the fuel filter is only a year or so old...
I'll let you know...

No I am talking about the hose that goes on the fuel pump inside the tank.

I had mine crack once and it wouldnt build pressure.

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
