Misdiagnosis is the leading cause of fuel pump problems and returns. Often, a voltage drop test is the only effective way to find excessive resistance in high amperage circuits. It’s a quick and easy test that will give you immediate results on whether you have a good connection or a bad one.
Many people think that using a higher grade fuel is better, but you should be using the grade recommended by the manufacturer. The short version of the truth is that the higher the octane, the less combustible the fuel is and the slower it burns.
The inertia switch is a safety item incorporated by Ford in the fuel system of its vehicles. The only time the inertia switch should trip is during a collision.
Performing a voltage drop test and you find the ground side shows a high resistance or high voltage drop, one of the first places to check is the ground location on the vehicle. Look at your wiring schematic manual to determine where the ground is for your particular vehicle. Video Demostration Included!
In the past 30 years, the fuel injector has moved from the intake manifold to the combustion chamber. During this evolution, injectors have become more precise in dispensing fuel. If this precision is thrown off by restrictions, electrical problems or fuel problems, it can cause drivability issues.
