03 6.0 keeps blowing fuel pump fuse

I was driving down a very bumpy logging road today to go out shooting. I parked the truck for a while to unload and then went to fire it up. The truck started and with in 3 seconds it died. I checked the fuel pump fuse and it was blown. I replaced the fuse and the truck ran for a couple minutes and blew the fuse again and again. I checked all the harness and everything looks good. I am thinking all the bumping around has cause the pump to short in the tank some how. What do you guys think?

Pump is under driver seat, inside frame rail. Check wiring harness, and amp draw on pump

I made my Samsung SGH-I997 send this.

Ok so an update. Now the truck will blow the fuse right away without the fuel pump even plugged in. I have checked all the wiring and all of it looks good. Im now thinkin that the fuel pump relay in the central junction box is bad.

Bad relay shouldn't blow a fuse

Once the FP relay is energized, the power to run the pump goes to the Inertia SW first (across the dash, to the pass side kick panel and back). That's a long way with the opportunity to develop a short somewhere...

I happen to find the short by chance. Unfortunately not before I had the dash and stuff all apart. I was looking through my fenderwell to unplug the harness and noticed something interesting out of the corner of my eye. When they cut the fender well to install the longer shock towers they did not secure the wiring harness away from the shocks. Going down the bumpy road had caused a good amount of rubbing between the shock tower and the harness. Long story short I fixed the short and put everything back together at cost of one day lost of work, wiring supplys and zip ties.
