One particular fast and straightforward way to test a fuel pump will be to measure The present flowing through the circuit by using a digital volt/ohm meter (DVOM). This test will only clearly show if present-day draw is just too low, indicating high resistance someplace within the circuit; it will not likely pinpoint the trouble.
The Management module operates the fuel pump by controlling the motor’s ground circuit on the pulse width modulated duty cycle.
It’s probable difficult to push your automobile In case the fuel pump is faulty. Substitute the fuel pump Should the vehicle gained’t commence. Soon after letting the engine amazing down, consider starting up the vehicle.
These kinds of fuel pumps work constantly although the motor is Performing. The powertrain control module (PCM) within your automobile regulates the Doing the job of the pump.
