Hello, why are you having to put gasoline into the Throttle Body? And the fuse that is blowing, is that the ECMBATT Fuse 9 20amp? The Relay behind the glovebox is the Fuel Pump Relay, so if you're having to put gas into the Throttle Body to get the truck started that is why. It sounds like there is an issue with the Fuel Pump or the circuit that controls it., If that's the correct fuse, that fuse powers up the Fuel Pump relay and sends 12volts to the ECM. The Fuel Pump may be having issues due to a clogged filter, its worn down due to its age, or there is an issue with that circuit.
