lift pump not getting power?
the lift pump on my 6.5 gmc diesel isnt getting any power. we had to run a hotwire to it to get any pumping action. the relay and fuse checked out. any idea?

trace the circuit
the wire going from the relay to the pump is bad. I will hotwire it with an on/off toggle for the time being
The lift pump may be drawing too much and could have caused the wire to fail. I would put an extra fuse in your temp wire and use the correct amp fuse for the pump.
Turned out to be two breaks in the wire from previous splicing that had been badly connected. Two new connections and we are pumping again
Glad you got her goin again dude!
Thats good news. Glad it was a simple fix.
