7.3L Powerstroke PCM Testing Service (1994.5–2003)

If your 7.3L Powerstroke is experiencing no-start conditions, communication issues, or unexplained driveability problems, this PCM Testing Service from Diesel Technology of Chattanooga provides a professional way to accurately diagnose the problem before replacing parts unnecessarily.

This service is ideal if your PCM failed unexpectedly, was damaged during tuning, or if you’re unsure whether the issue lies with the PCM, IDM, or related control systems.

🔥 What This Service Does:

• Performs a complete bench test of your PCM

• Identifies internal failures, signal issues, or communication problems

• Determines whether the PCM is repairable or beyond recovery

• Provides clear diagnostic results and next-step recommendations

• Contacts you directly if the PCM or IDM is found to be unrepairable

⚙️ Comprehensive PCM Testing Includes:

• Verifying the PCM boots up correctly

• Testing activation of:

  • Glow Plug Relay / Module

  • Fuel Pump

  • Injector Driver Module (IDM)

🧪 Detailed Results & Feedback:

Once testing is complete, you’ll receive an email summary of the findings, along with recommendations for additional troubleshooting steps if the PCM tests good.

📋 Performance Chip Testing:
