05 wiring problems, Maybe Dead ECM? Someone please help

642 3
I will try to put all of the problems in the first post. I have worked on this rig all day yesterday and figured out I have a chore ahead of me. The #1 cylinder has blowback, and SOMETIMES it will not start unless I unplug this plug and slide it back together.



I have checked the prongs inside, checked other wires and plugs, but nothing changes or makes it work unless I slide this plug apart and put it back together. Do I have a short in the ECM? I am wanting this wiring problem to be cured before I pull the engine for a rebuild. The key trick has thrown codes at me at random, But all of them are sensor voltage high or low (everything from fuel level to MAP sensor) If you are a wiring expert or know one, Please show them this thread! I want to get started on the engine build, but not until I can get in it and start the rig every time. Thanks Chris:thumbsup
