If you can't get the scan too to communicate and there is no "wait to start" light, you definately have a blown fuse. Pull #22 (30a maxifuse) and check it good. If you are using a test light to check it, even a blown fuse will check good on one side.

I know on the Super Duty that fuse #19 and #30 also affect the PCM but not sure on the OBS. Does the cigarette lighter work?

yeah the power point fuse is good i checked all fuses they r all good is their anything else that could cause this like the idm or something

I'd say PCM before the IDM just because of the no "wait to start" light and the fact that you can't communicate with the PCM. Hopefully someone can chime in with some more info.

The PCM or IDM? The PCM is behind your e-brake bracket and the inner fender well needs removed to get it out very easily.

the pcm is what i took out and put in my buddys truck yup took out the inner fenderwell to get it out of the slot

You say that your PCM works in your buddies truck, did you try his PCM in your truck?? Might be worth a try.
