Wiring problem fuel pump keeps blowing fuse. need to knowwhere the wiring runs from computer to fuewl tank.

You may have a short in wiring to fuel pump. Try this! remove the wires from fuel pump, then turn key to start the car briefly. If the fuse does not blow, its likely the fuel pump is drawing to much current and blowing the fuse. God-Bless!

If its started to blown fuses after the fuel pump maybe there a wire that got sqeeze between the tank and the body of the car that create a short

if its running OK I'd bet on a frayed wire

short to ground likely on fuel pump circuit.. trace from tank up frame rail to PCM.. you probably pinced it though when you replaced pump so look carefully at wiring at between tank and body

test with volt meter ensure its within operational threshold

My first thought is that you have wires shorting out somewhere, probably right above the gas tank. Either way, you're going to have to pull the gas tank off to find it. Usually, when a fuel pump dies, it just doesn't work, and won't normally blow a fuse. Pull the tank down, inspect the wiring, and change the fuel pump if the wires check out okay.

If you keep blowing fuses you need to trace those wires back to the Engine area and find the short that is causing that. Start at the tank and work your way forward.

the fuel pump and radio are not on the same circuit, most liokely the fuel pump is shorted, that is the most common cause, get under the truck and disconnect the fuel pump connector at the tank, if the fuse doesn't blow then u need a new pump.

You could have a short in the wire harness to the fuel pump or the fuel pump it self is bad or the relay has gone bad also. Start with the replacement of the fuel pump relay and also find the wire harness to the fuel pump sending unit from the frame to the gas tank and disconnect the connections. If the fuse does not blow when the connection to the fuel pump is disconnected, then it's a go chance that it's the fuel pump. If the fuse blows and the wire harness is disconnected, then the problem is towards the fuel pump relay and fuse block. Good luck and keep me posted, be glad to help you get your car running 100% again. 

where wire run to pump over fuel tank i thing you will find they are chaffed .use a lenth of twin flex and rewire it quickest and easyest
