All right , I have been helping this guy I know with a fuel pump install cause he had a stock one. Well I sell him a 190lph for $60 and install it for him. The car cranks up and ran fine for 2 days. On the 2nd day his car just shut off while he was driving. Now its sitting in a parking lot. I felt like $hit because I thought the pump I gave him was bad. We put in a brand new 255 and nothing. You cant hear the pump kick on when you turn the key in the on position. So we replaced the relay under the seat. Still nothing. I havent busted out the multimeter yet cause I was on post at the time. Could a wire have just gone bad while he was driving? Do I check for power at the relay first? This ever happened to anyone? And yes the enertia switch is reset. Thanks guys.
