I'm no diagnostic pro, but it could be the uvch, have you done the 50 cent mod or checked the uvch?

It's uncommon for the uvch to come disconnected at both sides. When mine did it it was on the passenger side and it ran but very roughly. Slipped a quarter in both sides though have you looked up those codes? If it was the uvch it shouldn't throw those codes. But I could be wrong too...

Just looked it up. It says those are misfires on cylinders 1 and 2. Have you checked compression lately?

Ok so I went back out to the truck, now the wait to start is flashing along with the over drive off and my service engine soon light and there is some strange like humming and clicking but can't tell if t is from the back of the engine or the firewall,

WTS light flashing? I know that if it doesn't come on it is a PCM issue. I'm stumped... I'll look and ask around if I have time tomorrow

Possibly. It's simple to get to. You are familiar with the uvch right?
