Well I appreciate all the help that DaveD has given on this problem but after trying your last idea, I've still got the interference. I'm still going to work at it but as for now I'm going to live with it. * A warning to anyone else having this problem: If you unplug the fuel pump and have the key in the "on" position, then the fucking computer in the truck thinks its smarter than you and will turn the fucking "service engine soon" light on. And then I had to go to the Dealer and find some one who understood what the hell I was talking about. "You can't do that only we can do that."-Moron
