OBD port wont work

Today on my way home from work my truck acted funny. I new to the diesel world. I had only drove about two miles from work and at an intersection I put it to the floor until 50 mph and let off. It seemed weird and quite. I push on the accelerator and nothing so I let off and looked at dash, the check engine light was on and instantly off. Pure luck I saw it on at all! I tried pushing on the accelerator again and it the truck took off normal. So when I got home I went to hookup my OBD code reader. It would not turn on like normal. I know that GM uses the lighter fuse for the OBD port so I check and it was okay. I check all fuses under dash and hood and they were all good. What is going on with my OBD port? Also what did I experience with my truck. Seemed like it was in limp mode????

A OBDII scanner. The scanner will turn on if I manually turn it on but it says that it must be hooked up to a vehicle. It works on my other vehicles. I had it happen once on my cousins chevy and it was because the cigarette lighter fuse was blown. All my fuses are good I checked last night.

OBS PSD's are all (supposedly) only OBD I. youll need an old school scanner to read them, or Snap on with a ford cartridge or AE (Auto Enginuity) with the Ford budle to read and run diags. some other guys here should be able to list some other scanner options.

Is the Matco scanner as big and expensive as the Snap On? If so I am going to need to find someone with one that wont mind reading my truck. Does anyone have some ideas on what I experienced happen to my truck?

I think it's a CAN system, not OBD.

My truck is a 1997 F350 4x4 7.3 with auto trans. The port was located on passengers side just below and left of the glove box. My OBDII scanner plugs into the port just wont talk back and forth to the trucks computer.

That's correct, I bought the Matco for $600 used. It was a Proscan.
