My brother and I changed out his valve cover gaskets but messed up when attaching the plug wires. We had them wrong when we started the truck; knew pretty quickly when the truck would not run. We looked in the manual and got the wiring correct but now the number 3 cylinder is dead. We pulled the spark plug and the metal tip looked bent. I don't know if when starting the truck with the incorrect firing order caused this. We have good spark so it is something else.
Was wondering if anyone else made this mistake and experienced the same problem. I am thinking it may be a valve issue but have never been inside this motor. When ideling the truck sounds fine, a little rough, but no metel to metal sounds.
