Common Symptoms

When the diesel supply pump fails, you may experience a hard starting engine, hesitation when accelerating, cylinder misfires, and/or an overall lack of power.

This pump supplies fuel to the diesel injection pump. If it fails, the injection pump may also fail due to the lack of lubrication from the diesel fuel.
