1 fast and easy way to test a fuel pump will be to measure the current flowing from the circuit which has a digital volt/ohm meter (DVOM). This check will only present if existing draw is simply too low, indicating higher resistance somewhere inside the circuit; it is not going to pinpoint the situation.
Keep pressure can leak down on account of a leaking injector, but This is often a comparatively gradual leak. If keep tension leaks down instantly after the engine is switched off, that’s a bad check valve.
The rotation with the pump’s electric motor initiates, and it rotates for a long time to improve the fuel program pressure. The PCM timer boundaries the length of time where the pump will operate prior to the motor begins.
