i would check your main fuses for your fuel pumps. If that doesnt work i would look at the lines to the pumps and the switch i beleave that the switch is vaccum opperated.

Before you change fuel pumps check to make sure your getting power to the pumps. The pumps here are about 140.00 each and I found this was not my problem. Check fuses,relays and the shut off switch. The only thing I have not replaced is the tank change switch. My truck is still sitting in the drive way. Let me know if you found out what works,

I just had the same problem. Listen for the pumps. No noise. No power. Mine was the wire coming of the negative terminal. There are two connectors. One was separated. Put it together and taped it and she started right up
