Need some wiring help from the experts

[sdgxxr]

Hey guys,
Was all ready to fire up this morning when I ran into a little issue. I'm completely stumped on this one. Can't get the external fuel pump to turn on, on key on through the RF relay.

Currently using:
RF Wiring Harness complete kit
FAST EFI Harness

Connected the FAST EFI relay cable to the fuse box as instructed. And nothing. (For a test I did run a 12v cable directly to the pump and the pump will run at key on)
Double checked the Inertia switch and I am getting a ground at the relay
Double checked the voltage from the fuse to the relay - good as well
Double checked I was getting a ground signal from the FAST EFI wire, good as well.

Not sure what I am doing wrong at this point. Any suggestions?

If I understand your pic, you only want one ground. one of those legs has to be 12 volts. disconnect one of the grounds and jump 12 volts to that terminal and I bet the pump will start.

If the Fast EFI uses a ground to activate the relay, then you need to reconnect the tan wire and intercept the ground wire at the "live side" of the inertia switch. Or just remove it and allow the FAST to supply the ground.

Thanks Michael. Yes, the Fast EFI uses a ground to activate the relay. So I would need to reconnect the tan wire that was cut and connect the Fast EFI wire to where?
Sorry for the dumb question, very green when it comes to wiring.

You need to re connect the tan fused hot that you clipped off back to the coil where it was originally. The Fast EFI ground will go inline with you inertia switch. If one end of your inertia switch leads goes to ground then this is the one that will now go to your Fast efi ground instead. Your efi will provide the ground instead if that makes sense.

Just cut the ground wire on the inertia switch that doesn't go to the relay. Then attach the FAST ground wire to the inertia switch.

Yup, that was it. Thanks guys pump is working as expected.
