Fuel Pump Draws Amps at Alan Burke blog

Fuel Pump Draws Amps. Why test voltage and amperage. How to perform the test. Next day i replace the fuel pump relay with a new one from autozone and it works for 2 hours of plowing then dies. Use low amp probe and oscilloscope to diagnose average fuel pump amperage draw. Reveals if the pump is overworked, shorted, or has internal issues. Verifies that the pump is getting the right amount of power. The purpose of this test is to investigate and examine the current draw waveform from a vehicle fuel pump. Fuel pumps can draw as much as 15 amps at peak and the fitech can run a fuel pump in pwm mode straight off the ecu. Pinpoints problems in the pump, wiring, relay, or fuse. Low fuel pressure or delivery problems can be caused by a worn or damaged fuel pump, a faulty pressure regulator, a clogged fuel filter or by high resistance in the fuel pump circuit. Fuel pump relay current draw specs. An amperage level above or below the specification indicates a malfunction is present, if pressure is low and amperage is above specification. That means there are two ways to test a fuel pump:

An amperage level above or below the specification indicates a malfunction is present, if pressure is low and amperage is above specification.
