When your 1997 F250 6x4 with a 7.3L Diesel Power Stroke engine isn't performing as expected, the expert team at Howard Motor Repairs in Howard is ready to provide top-notch diagnostics and repairs. Recently, we encountered a challenging case where the vehicle was running on only four out of its eight cylinders. This issue necessitated a detailed examination to identify the root cause and ensure the vehicle could return to optimal performance.

Utilising advanced diagnostic tools, we confirmed the issue with an oscilloscope, revealing that one bank of the engine's fuel injection system was not firing. Further investigation pointed to the injector driver module (IDM), which was not outputting the required signal. This highlighted the need for an intricate approach to ensure all components were functioning seamlessly, avoiding further damage and ensuring reliability on the road.

The technical team at Howard Motor Repairs proceeded with a thorough continuity check of all wiring leading to the injectors and glow plugs. This meticulous process identified areas that required repair. Upon inspection, the IDM was found to be full of corrosion—a known common problem in similar models. This corrosion was disrupting the module's performance, highlighting the importance of regular maintenance and checks to prevent such issues.
