Whenever the ignition is turned on, the fuel pump relay will supply or “pass on” a consistent voltage to the fuel pump. Therefore, problems with the relay will result in the fuel pump malfunction, which in turn will cause start-up issues! The relay is vital for the function of combusti...
In the wiring configuration below, the universal fuel pump controller PURPLE wires are set up as a ground switch circuit. One of the PURPLE wires goes to ground and the other becomes an output and gets connected to the respective relay circuit to trigger the relay "ON." Using this diagram,...
To minimize the risk of fire when replacing a fuel filter, make sure there are no sparks or open flames nearby (NO SMOKING!). Also, do not allow any fuel to make contact with a hot exhaust pipe, exhaust manifold or the catalytic converter. And if your using a trouble light with an i...
