    thanks for the help on this. strange thing on my 1987 k10 I un hooked that to see if it was and my truck started anyway. I will switch out the relays and see if I can get some miles on it.

    where did you get the diagrams?
    thanks again.

    The reason why it started is that there is a backup to the fuel pump relay in the form of an oil pressure switch on your engine. When it sees 10 PSI of oil pressure, it closes, and allows the engine to start :)
