Help Please

I have a 2005 Excursion with the 6.0. I have a SCT Livewire on it. It has been running great no problem. I got off work this morning (40 degrees outside) and started to drive maybe 1/2 mile. I noticed the check engine light & the check gauges lights were on. Also my RPM gauge was at 0 while driving . So I pulled off the the side of the road and was going to shut my truck off and start it again. I shut it off and then it would only turn over.

So I checked the SCT to see what codes there was. One of the codes was a fuel level code ( which I believe popped up because the RPM gauge not working_). I cleared the codes and tried to start the truck again. Now it wont even turn over. I can hear all the injectors buzzing as normal when I turn the key on.

I now have a U0155 code. So I looked it up and found out it has something to do with the instrument panel not communicating with the motor. I searched the internet and theres not much on how to fix this code. I tried to clear the code but it wont go away.

So I need information on how to fix it. If there are sensors or wires or connectors please tell me where they are located. I did take the gauges out a few months ago to place a white overlay but never had problems since then.

Thanks

Oh and I had to drive all the way home to get a truck and trailer. I had to use a come along to pull it up the trailer by my self tall swamp buggy trailer. It sucked B@lls

I came back today and it wouldn't start. I unplugged the ICP and tried starting nothing. The only lights that show on my gauges are glow plug/start light, ABS, theft. My radar detector tuns on and off fast( plugged in the coverage lighter) and when I turn the key on to start all my gauges move to there max position. Also my SCT live wire shuts off when I turn the key on to check engine codes. The SCT turns back on when the key is turned off. I need some help quick......

Did you figure it out or still dead? My 03' did something on the same lines but after a batt swap and new alt. it was good to go. But now I have a crank no start issue. Looks like we are both up the creek with no paddle. Sorry I have no good sugguestions for you.
