Most automobiles now have an Digital returnless fuel source system that has no fuel pressure regulator. Stress is controlled by a fuel pump driver module (FPDM) or possibly a fuel pump Regulate module (FPCM) in reaction to instructions with the PCM. On these units, fuel tension is managed by controlling the speed on the fuel pump.

Minimal fuel strain or supply troubles may be brought on by a worn or harmed fuel pump, a defective strain regulator, a clogged fuel filter or by significant resistance from the fuel pump circuit. That means There's two ways to test a fuel pump: mechanically and electrically.
