Ok here is an update on my situation. The crank sprocket that turns timing belt and the thin metal plate slipped and the steel ring/ spacer is broken the three pieces. Ok dealer can order all three parts. And hope all goes well after that. By what I can tell it looks like who ever had truck before had the number 4 coil wire on number One piston on so on. I am guessing motor was 180* off. So now if I set my cam sprocket timing marks and my crank with new parts and line up marks on block I should be able to set wires back to normal right. Or would there be something in valve train that was done backwards that would prevent me from going back to normal firing order. Can I pull valve covers and see if valve are open or closed on number one cylinder at TDC?
