As the title says, the fuel pump in my car is not working, its basically a new stock pump, ( after a plenum pull which I have done several time in the past without problems afterward)I've tried the fpcu by-pass nothing, the relay is good, the problem is no power at all to the pump. The engine and body earths are where the should be clean and grounded. The only other thing I've done wile the plenum was off was to replace the nistune board which was socketed by big bob, Some may remember him, with an different tuned eprom. I can't see how replacing the nistune board with another eprom could cause the fuel pump to stop working, but I'm about to put the nistune board back in so i can confirm it. Any ideas?
