Replaced original fuel pum in Aug 2015. Truck wouldn't start last week. Couldn't here fuel pump running or engaging with the key on tested pressure at the rail and got 10-20 pounds. Figured it was dead. Went through a nightmare getting a replacement pump from parts supplier s they said it was on backorder. Finally got a pump.

installed the pump, the truck wont start. Tested the fuel pressure gauge shows 39 pounds, which is 1 pound below running pressure and 10 pounds short of starting pressures.

Pulled the fuel pump relay and jumped the connections and got 39 lbs again. I am assuming the wringing is working.

is there anything I am missing? Is this another New part failure, that us old bastards love to complain about?
