12PSI of Fuel @ WOT?

[Hickfied]

12v into Fuel pump relay, 6.8v out?

With the key on, I have 12v coming from the yellow wire (12v fused hot) into the Relay box. with and without the fuel pump jumpered at the diagnostic port, I have 6.8 volts coming from the dark green/yellow wire, going back to the inertia switch and to the pump.

My question is, is this enough for the pump to function? With the key on, my pump will not prime. I have no clue when it comes to electricity.


PS, can I hook a wire from the pos and neg side of the battery to the pump to ensure it works? My neigbor was helping me install the pump and mixed the + and - wires up on the pump, which has turned into a big headache for me

Fuel pressure will naturally be lower @ WOT because the maximum amount of fuel should be flowing through the injectors, but I think it should still be a little higher than that.
Did you change your fuel filter?
Do a vaccuum test on your regulator if you can, see if any fuel is leaking past the diaphragm.

I just found out it's the pump.

Already have a new filter and regulator as of last week.

I just purchased the pump two months ago... And it has already went out.

Update, when jumping the yellow and dark green/yellow wires @ the relay, the pump primes. Anyone know how to wire up a new relay?
