LOSING POWER?
USING MORE FUEL THAN NORMAL?

Caterpillar fuel injection pump and injector faults often show up as hard starting, excessive smoke, loss of power or increased fuel consumption. These issues are commonly caused by worn injectors, incorrect calibration, fuel contamination or internal pump wear. Proper bench testing allows us to accurately diagnose Caterpillar fuel system faults and identify the root cause before unnecessary parts are replaced.

Common signs your Caterpillar fuel system may need testing or repair:

Hard starting or no start issues.

Loss of power or poor throttle response.

Excessive black or white smoke under load.

Rough idle, surging or intermittent cutting out.

Increased fuel consumption and operating costs.

Engine running unevenly or misfiring.

Lack of power when towing or under load.
