No power to fuel pump .pump is new .cant find fuse .is fuse on own or shared
SOURCE: NO POWER TO FUEL PUMP
You may use another brand of relay (say Bosch) then let your electrician make a retrofit to match the connection of the original . Make sure that the current (amps) rating is the same or a little bit higher than the original. If you can't get a unit with higher current rating, use 2 or 3 and connect it in parallel.

At the fuel pump relay you should have 1 full time hot wire. 1 hot wire when you turn on the switch. 1 ground, and the other wire goes to the pump. Test the ground to be sure it is good. If so then jump a hot to the one that goes to the pump and see if it runs.If it does then you have a bad relay or ECM. You can swap the relay with another of the same # from tour fuse box to test it.There is also a ground on top of the frame near the filler neck, check it too. Good Luck

Did you verify that the relay terminals have the appropriate signals to them?
ECM fuse B (20-amp) should provide power at all times to the orange wire of the fuel pump relay. The relay coil receives ground via the black wire, and relay coil gets power from the dark green/white wire. When the relay is closed, you should have battery power on the gray wire.
The relay trigger wire should have power from the dark green/white wire in terminal 1 of the Vehicle Control Module (VCM) connector for the first couple of seconds after they key is turned to run (to prime the system) and when the truck is running. Checking for all the appropriate signals at the relay is where I would start. That is after I checked for diagnostic codes.
Believe the fuel relay is the middle relay out of the three in the left rear of the glove box. Last thing is to hot wire the fuel pump if you can not get it scanned, see if the pump is bad unless your going to have a shop work on changing the fuel pump.
Good luck and hope this helps. keep me posted.
