Removed insrument cluster - now won't start
 

I had a instrument cluster going out, so I pulled the cluster, drove the truck home and was going to take the cluster in for a rebuild. I changed my mind and reinstalled the cluster, but now it turns over but won't start.:argh:

Did you have the batteries disconnected? try that first for 30 min. I don't think that has anything to do with your no start. Any codes? Be sure all your connections are good. The anti theft system and key fob are programmed to the truck ECM but not sure if a reflash is needed. Check the simple things first it's easy to blame the last thing you touched but just start from easiest up!
