2000 Jimmy won't start

Asked by Dec 29, 2014 at 03:10 PM about the 2000 GMC Jimmy 2 Dr SLS SUV

Question type: Maintenance & Repair

I replaced the fuel pump, I checked voltage at the connector, turned the key on and get 12v for 1 sec or less, turn the key off and get 12v for the same amount of time. I hooked the pump up and hear the pump cycle for the same amount of time. I pour gas in the throttle body and it runs until it uses the gas I put in
