I have a 3406E 6TS in a 1997 kenworth T800. It started last Friday I had a problem with my marker lights cutting in and out. Found it to be a corroded fuse under the dash. Found a few others and pulled them. Cleaned the terminals in the fuse block and reinstalled the fuses. The truck then sat all weekend. Monday I put a new dimmer switch in the dash as well as new Jake switches out of a parts Truck I have. Went to start the truck and no start. Thought maybe it lost prime. Nope primer is hard. Replaced the cam sensor. Still no start. Replaced the engine side harness. Still nothing. It will fire on either but then dies off. No smoke during crank. Thanks in advance for any help.
