2001 ctd Holley blue added to factory harness. 20,000 miles since install. Truck cranked, then died. Will not start. When key is turned on, fuel pump is powered for less than 1 second, then cycles out. Changed relay, Unplugged Holley, still shows power for less than 1 second. Any ideas?

I am working on this myself. Only my pump just quit and will not power up. When it was working it would run until pressure was built up in the line and then it would stop running until the engine started. Have you tested the power leads with a multimeter?

I am in the process of installing an Air Dog 100 but they sent me the 2005-2009 model instead of the on I need for the 2004 with the fuel filter mounted pump.
