Default Re: NO fuel pump...

Thanks, USMC.
The fuel pump was a used one I had that was working before I removed it sometime ago.
My immediate concern is the lack of indicated fuel pressure on the gauge attached to the fuel rail. I'm going to open up the fpr and see if that's it. In my haste last night installing it, I didn't adjust it any. So maybe it's closed, but that's pure hope right there.
I'll also check the plugs. If they are dry, guess I'll be dropping the tank again and verifying power is getting to it first, then replacing the fuel pump.

I'm going to call around too about the computer compatability. My understanding from reading around the net is that A9L's, A9P, A3M, X3Z, yatta, yatta, are all interchangeable, regardless of transmisssion.

I'll keep you posted, thanks for your input.

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.

Default Re: NO fuel pump...

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...
