I have a 2002 6.6 liter that just quit running. My gauge reads a quarter tank and i only see two wires t the lift pump. I checked the voltage to the lift pump and it reADS 5 VOLTS. That does not seem right. Does anyone have any insight in my problem. Any help would be appreciated. Thanks

 

did you install a lift pump? then there aint one. 5V is usually a reverence voltage for a sensor

 

Same question, what lift pump?

 

so what was the problem here?
