My vehicle is a 2005 Mazda B4000 4x4 X-cab...
Ok I was driving home,and my truck just shut off..I checked the fuses and the fuel pump fuse was blown.I put another in,and as soon as I turned the ignition forward without even trying to start the engine..It blew again..did this a bunch..Next I turned the ignition on and then put a fuse in..fine,but as I tried to crank the truck..fuse blown!Over and over,as I tried to wiggle wires here and there..
All of the sudden I put a fuse in,and the truck started...ran for 5 minutes or so.I tried to drive it..got 100yds,and it died..Fuse blown!
Next I figured it was the fuel pump shorting out,we took the bed off,unplugged the fuel pump,put a fuse in,and POP same thing WITH THE FUEL PUMP DISCONNECTED!
Next I switched Relays around,and then the problem went away!Put the original relay back,and problem was still fixed..Basicially I have done nothing to fix it,besides switching relays around,and putting them right back in,and it is not blowing fuses..WHat in the world!!
Tomorrow I'm going to get it back together,and drive it to see if it blows a fuse..
What could be going on??Thanks in advance!

Sounds like you have a short in your wiring harness or another circuit that is powered by the same fuse. Look at a wiring diagram & see if that fuse powers any other systems.
