Using Scan Tools To Diagnose Faulty Fuel Pumps
The most common diagnostic procedures for fuel pumps in the past were analog and hands on. Most fuel pump-related problems could be solved with a pressure gauge and voltmeter. Today, the scan tool is the most important tool when diagnosing a fuel supply problem.
Diagnosing Fuel Pumps Using Voltage Drops And Current Testing
Some of the best diagnostic tests for fuel pumps are voltage drops and current testing. Fuel pressure and volume are influenced by voltage, current and the demand controlled by the regulator. If a fuel pump is not receiving the correct voltage, it cannot spin fast enough. Voltage drop testing can isolate problems that can still remain even if the pump is replaced.

Fuel Pump Diagnostics – Using Voltage Drops and Current Draw
Fuel pumps and voltage drops are never a good combination – at least the wrong kind of voltage drops. Good voltage drops occur with fuel pumps that are given multiple speeds with a module that is connected to a computer with a dedicated signal wire that tells the module to go to a lower or higher speed.
