Testing the ecm for power?

Friend of mine has a 95 f350 rollback. It died on him the other day, and he had to have it towed home. The symptoms....no wait to start light, it does have a check engine light, and will spin over but no fire. Checked all fuses.
I hooked a scanner to his truck at the diagnostic port and got nothing. No power to the scanner. I hooked into my truck, to make sure the scanner was working fine. It was. I have used the scanner on another 95 f350 and no it will work on that year model as well as others.
Any ideas?

Chuck

check fuse

I believe there is a fuse that gives power to the port that you hook the scanner in. I, off the top of my head, can't remember which one. But it should tell you on the cover of the fuse box, or better yet check the manual. Good luck. One of the actual techs may have more for ya.

I get a wait to start light, the truck starts, runs and drives just fine. The check engine light is on, but I have no power to the On Board Diagnostics port, so I can't scan it either, any other ideas?

Had similar problem with my 97PS except that the scanner would not bring up any codes. Thought it was my ECM but we took the ECM out of my 95 and it started the 97 which eliminated the possibility of an ECM problem. Turmned out to be the IDM. I took it to Ford and was robbed by them to the tune of $834 for the IDM. It was a reman that they put in and that is my last trip to Ford. Saw reman IDM's for under $250. Shame on me but I won't go back again
