Abs and airbag lights, no blinkers, no cruise control, no speedometer, no odometer, a

I have been having these problems intermittently when the truck starts, but they usually go away after a few minutes. Initially I was thinking the batteries could be bad, or the alternator. Then was thinkin the speed sensor or PCM. I looked on the forum and there's a lot pointing to the clock spring, but my horn is working...

Any thoughts would be appreciated... I haven't seen a clear resolution posted on the site, mainly just a lot of questions. I will be taking the batteries and alternator out for testing tomorrow. Then I'll pull the speed sensor to see if there may be shavings on it. I will post what I find...

HELP!!! Its not the ABS sensor, or the battery/charging system... Hoping that it is just a Loose connection in the PCM, but my luck is not that good! I checked some fuses, which were all good, but the interesting thing is that there was power supplied to the PCM, but no power to the airbag or abs systems that I could tell from the fuses...

Come on guys, let me see some ideas!!!

Maybe your ignition is getting stuck in the start position instead of returning to run. After you start it make sure the key turns back a little.

I will check that, I guess the switch could be going bad... Might not be making good contact.

Yeah I have to find some time to dig through some schematics and see if I can find something that they all have in common. I checked voltages on some fuses and there are a few that should have power relating to the abs, airbag, and a few other things. Them not having power makes me think it could be a relay. Maybe one that should be clicking after startup or something...

Looks like a relay problem... I did a little tapping under the dash and everything started working.
