Thank you that makes sense. I'll try that this weekend.
I was reading on another site that it sounds like a ground wire. Everyone was having that same problem and about 80 percent was that damn ground. It's on the firewall about dead in the middle. Take off the plastic vortec cover and you should be able to get to it.
