I've had a FASS fuel system for about 4yrs. I just recently had to replace the pump due to pump worn out. It started grinding and only held 14psi and under throttle help 7psiI put 48,000miles on that pump. So I replaced it with a 150gph adjustable pump and just reused the original harness and that was about 3 months ago, and up till now I have had no problems with it. When I first initially turn on the key the fuel pump will run for about .5sec and then shut off like it always did, but then if you bump the starter to get the fuel pump to run for 2min it wouldnt do anything. I checked the relay and the FASS connection and the inline fuse and they were all good, I wiggled all the connectors and still did not seem to help. Has this happened to anyone out there, its dark and I dont have a flash light, but i was wondering if I could get some pointers for tomorow. I think Im going to replace the Harness first with a new one and see if that changes things, since that will only take 5min.
