[QUOTE="Constant Mesh, post: 235162, member: 615"] The positive side of the injector coils are fed +12 volts from the fuel injection system relay. The negative side of the coils are switched by the ECM. If the engine will run with a separate power source for the pump then we know the fuel injection system relay is powered and pulled in. Otherwise the injectors wouldn't work. [/QUOTE]
