Can someone please point me into the right direction where I can find a list of correct voltages for the fuel pump circuit?

I am after the fuel pump relay and the fuel pump connector voltages.

 

+12V whenever power to the pump is on.

 

Would the pump run at 11v?

I have made a funny discovery and am wondering what could cause this. If you have a spare 5min can you check it out to see what you think.

Under TPI Forum - Fuel pressure playing up New AFPR did not solve the problem.

 

It'll run at less than that even.

 

Interesting well I hope my voltage is low as that is the only thing other then the pump dying. I seem to be having fuel pressure probs and looks like a lack of flow from the pump.

There is a test that you undo the fuel line at the motor run the pump for 15 seconds and you are supposed to get x amount of fuel. If the voltages check out fine above 12+ my last option is to replace pump.

Just that the headlight thing bugs me. Turn headlights on and 4psi drops off from the fuel pressure.
