7.3 Powerstroke DTC PCM Testing Service
If your 7.3 Powerstroke won’t start, won’t communicate with a scan tool, has unexplained drivability issues, or failed after a chip was removed with the key on, this bench testing service tells you exactly whether the PCM is good or bad before you spend hundreds on a replacement.
What’s Tested
Our comprehensive bench test verifies that your PCM:
- Boots up correctly
- Activates the glow plug relay/module
- Activates the fuel pump
- Activates the Injector Driver Module (IDM)
- Receives and processes the Cam Position Sensor (CPS) signal
- Commands the IDM to fire the injectors
- Activates the correct transmission shift solenoids
- Communicates with a scan tool
- Transmits accurate sensor values
Critical signals (IPR and EPC) are also checked on an oscilloscope. J3 port terminal repair is included at no extra charge.
Performance chip? Send it with the PCM — we’ll test it together at no additional cost. Do not send the cable or switch.
After Testing
- PCM tests good: You’ll receive an email with results. Your parts typically ship back the same day or on the next business day.
- PCM tests bad: We’ll call you to discuss options.
How to Send It In
Print and fill out the PCM/IDM shipping form and include it in the package. Customer is responsible for shipping to us (we do not provide a prepaid label).
Fitment: 1994–2003 Ford 7.3L Powerstroke (all applications)

I have a e99 f350 that I can not read with scan tool. Also I plug in my cts3 and it will not retrieve vin so it does not show sensor readings that I need for towing. Can this be gone through and checked? I believe my tunner was bumped out while it was running. A dial 6 position Swamp something company. I was told by forums this can burn vin cip and cause these issues. Hope you can help me

The chip coming out while it's running typical burns up computers. This can be diagnosed with this test or you can purchase another PCM from our website.

I would recommend Full Force to anyone. They are a pleasure to work with and did a great job for me. We had a problem with the order and when I called, the gentleman handled it to my full satisfaction. I’ll be buying my parts from them for now on. Thanks for a job well done.

PCM tested out fine. Was not showing a bounce on the tach needle, which a 2000 7.3 diesel will do. Cleaned the CPS connection with electrical contact cleaner. Now, it starts and runs. The guys did a fantastic job in testing the PCM.

I had a 1995 ford F350 that I have been working on for quite some time I really appreciate the guys at Full Force Diesel for your expertise thanks for your technical support and great products.
Shane Gurney (Conway) | June 5th, 2023
I sent in my PCM for testing, we were convinced it was bad. The Guys at Full Force were great and found the PCM to be functioning correctly. There was a little mix-up in the shipping but Chris made things right.

Prompt, professional and helpful, three things hard to find today.
