Just an update. We finally broke down and had Clark come out and look at our truck. After several attempts at finding the righ schematics for our truck and not having any luck, the tech used a manual out of an older chevy to check the rest of the wiring. He finally ended up finding that the windings in the distributor and broken down. He replaced the distributor and got us up and running again. 3 trips from the dealer and $1,000 and we are up and running and glad for it! Thanks for all of the effort on this.
