Where does the current from the fuel pump relay come from?
Where does the current from the fuel pump relay come from?
This voltage comes from the ignition switch. The fuel injection computer then grounds circuit 1. This activates the fuel pump relay to pass current from circuit 4 to circuit 3. Circuit 3 is the one that runs to the fuel pump (via the Inertia Switch) and delivers the voltage/current it needs to activate.
What is the high current circuit on a fuel pump?
The high current circuit is the one that delivers the voltage (and thus current) to the fuel pump in the gas tank (or on the frame rail). When the fuel pump relay is off (not activating the fuel pump), the high current circuit is ‘open’.
How is circuit 3 connected to the fuel pump?
Circuit 3 is the one that runs to the fuel pump (via the Inertia Switch) and delivers the voltage/current it needs to activate. Before this voltage reaches the fuel pump, it has to go through the fuel pump Inertia Switch first. If the Inertia Switch has been tripped, it will ‘open’ the circuit and the voltage will not reach the fuel pump.
