When a scanner cannot read the PCM and indicates no power to the unit, this typically points to a power supply issue within the PCM itself. The PCM (Powertrain Control Module) requires proper voltage to communicate.
For your 1994-2003 Ford 7.3L Power Stroke, this is a common issue that can stem from several causes:• Internal power supply circuit failure within the PCM
• Damaged power or ground connections to/in the PCM
• Blown fuses in the PCM power circuit
• Corroded connectors affecting power delivery
Our PCM repair service specifically addresses the power-related failures within the PCM. We rebuild the internal power supply circuits and test all communication pathways to ensure your PCM will properly function again. If you're experiencing this issue and have ruled out the power issues external of the PCM, our Ford 7.3L Power Stroke PCM repair service can likely restore full functionality. Feel free to reach out if you have any other questions about your specific situation.
