I apologize for all the posts, but I really need some advice on my truck. It's dead in the water at my local Giant Eagle again. So from what I can tell from research is that my computer is not getting power, when i turn the key to "on" the check engine light does not come on. Truck has no spark or fuel. I could usually give the harness by the relay box a wiggle and it would kick back on, but I think the connection finally gave out. It's about 20 degrees here in Western PA, and any help as to which wires I would need to check would be greatly appreciated. I have until tomorrow to get it fixed.

Thanks in advance, Joe.

 

Use the search function there are several threads on here by guys who had to open the harness and fix corroded connections.
Sadly from what I recall of the couple I read they had to open it up and just check each wire. The "good" here is that if I am recalling correctly the connections are all pretty much in that one spot where the harness runs over the fender well under the relay box on the drivers side. To be sure you should read at least one of them.
Sorry about the cold I don't miss eastern cold. Maybe throw a tarp over your truck like a tent and put several lights or a space heater under it to generate heat. I'm assuming you are at least close enough to the house to run an extension cord out.

Remember to disconnect the battery when you start cutting the harness open.
