The new connector works and fits it.

I believe it's wire wrong like you said.

Do you get battery voltage at the orange wire? (I believe you said it is connected to the gray wire.)

Also, is there continuity to ground via the black wire?

Yes, the orange wire set to be grey wire would be the 87 on the relay. All power is there even the 85 cones on for 2 seconds and stops.

Joe, what do you think I should do disconnect the fuel pump wires and only plug in the 3 wires instead of 4.

Hi,

The ground for the fuel pump is G103. It is located at the rear of the right cylinder head. That would (should) be the passenger side. I attached the schematic below.

Let me know.

Joe

Hi,

The power from the relay should be the gray wire. As far as what you are finding, it does sound correct.

I'm sorry for the delay in getting back to you. It has been a rough couple of days.

Take care and I hope you have a Happy Easter.

Hey Joe happy Easter. I was wondering does the van have an inertia switch?

Hope all is well with you.

Hi,

The van doesn't have an inertia switch. Ford uses them and not GM. On a GM, the ECM is what controls power shut down to the pump.
