Hello,

The fuel pump relay is Number 303 in the main PCD under the hood. Here is a guide and some fuse box diagrams (below) to help you get the problem fixed.

Your vehicle's fuel pump relay is located in the central junction box (relay 303 ) pictured below.

The central junction box is located behind the right side kick panel.

Truck will not start ** new fuel pump will not turn on, but truck does run if I manually add power via a battery, to the pump the truck will run. The fuel pump will not self-engage***any ideas?

Updated 3-1-09
Guys***I am sorry***but what is the PCM? And how do I check it? And the inertia switch? ***Have already checked all fuses***there is power at the fuse end of the fuel pump as well as power at the fuel pump itself, fuel pump will only engage when I hook directly to a battery! *** Where exactly is the fuel pump relay?
