Do you know for sure that the pump is running for five seconds when you turn the key "ON"? We chased a no-start condition on a buddy's Deuce coupe all afternoon in a hotel parking lot, only to finally find that he had hidden a pair of OEM master fuses behind the dash panel 25 years ago. The fuel pump fuse was blown, and every time we pressed the schrader valve on the fuel rail we were just bleeding a tiny spray of residual pressure from the last time it ran. We (three of us) all swore that we had heard the pump running, but we were all wrong....
