Genie S65 no start

Looking for more information on the PSI GM 3.0L engine. Engine cranks and has spark but the fuel pump is not getting power from the ECM. Suspect the crank speed sensor but it wondering if there is a way to check codes etc. The Genie manual has nothing on the GM engine.

    Disconnect the supply pump, if u can find the disconnect and apply 12v to it to make sure it works.. No sense it running down sensors, only to find u have a bad supply pump.. Good luck

    Alright just to update, I did jump the fuel pump, it works. Found some additional information on the engine. PSI built it for Genie and I was able to get a fault code list from them. Jumping two pins in the diagnostic plug flashes the fault codes. First code 123 is flashed four times. Then the faults after that. In my case it is throttle body codes. Need to determine if it is wiring or the throttle body but making progress.
