byron06, have you figured out your problem yet? I have a 03 1500 hd 4X4 and also changed out my pump after checking all the fuses and relays and only have 5 volts at pump, i also ran 12 volt lead to pump and the truck will start and run but only with the jumper. I seem to have 12 volts leaving the fuse box from relay and fuse but it is not getting to the pump, i also checked if the circuit ran to oil pressure swtich and i had 5 volts there as well, any ideas on where to check?

I may have the same problem as you have, i also installed a new pump and can only make it work with a 12 volt jumper, looks like i only have 5 volts at pump but i do have 12 volts leaving the fuse pump, did you come up with anything?
Thanks in advance

Yes! I did find the problem, it was the red connector that is under the fuse box (I think there are four large square connectors). That red square connector sends power to several things, but the very corner pin feeds the gray wire to the fuel pump. The blade (male part) of the fuse box was not making good contact with the female part of the connector, i do not know how that happened because the truck had always been running before with no problems and that connector is held on with a screw in the middle.
I was almost ready to change the contol module because that is what controls the fuel pump but i did have 12 volts at the 20 amp fuse that was not getting to the pump.

I Have a 1999 GMC Sierra. I replaced the fuel pump about 8 months ago. My cousin is a master mechanic and he helped me wire it up, the fuel pump I got from O'reilly Auto Parts was a universal style for a few different years of the sierra. On my model I had to reverse the power wires and rewire it with the supplied plug. (came with multiple plugs as different years have different plugs. If this helps, your welcome I wouldn't of figured it out on my own as always before red goes with red black with black... not red /black , black/red...

I am having the same problem i replaced the fuel pump it will start but just for a few seconds then dies. Can you hear your fuel pump come on when you turn the key on?
