    Do I need to have the Fuel Pump powered during cranking? I have the Aeromotive Pulse Width Modulator on my A1000 Pump, do I need power to the relay while cranking or can I just use 12v keyed and trigger the relay with the Ground Wire from the ECU? I am just reusing the relay that I had on my switched Carb setup, just not sure if the pressure will be enough I while cranking. I have updated my wiring with an American Autowire Classic Update Kit for my Chevelle, I know that most everything less the ignition shuts off during cranking.

    Yes - the fuel pump must be running while cranking. Switched 12V to the relay coil and the ECU will power the FP relay (by applying ground) when it sees RPM. The Aeromotive controller will see see the RPM (assuming you have it wired correctly) and turn on the pump.
