Diesel Injection Pump Replacement Cost
The injector pump may be replaced when the problem is actually dirty fuel filter(s), low engine compression, worn out glow plugs, failed fuel supply pump, defective glow plug relay, improper injector pump timing, and/or poor fuel quality.
The injection pump may fail if the fuel supply pump doesn't deliver the proper amount of fuel to the injection pump. Therefore, it's very important that the supply pump is checked and replaced if necessary.
Failure of the diesel injection pump can cause hard starting, cylinder misfiring, or a lack of power.
