Ok, my jeep 4.0l 5 speed started misfiring and check engine light started flashing. Code for misfire cylinder 4. Put a new set of plugs, new TPS and new PTS on. Now it will not fire, cranks strong but will not start. Got frustrated and shut the garage up for the night. Puzzled? i wondering now if I didn't get the PTS wiring snapped in good ( the wiring seemed to be about an inch short ) I also have never worked on an engine that didn't have individual plug wires and I wondering if I pushed the plug bar down far enough as I only barely tightened it down? Any thoughts?
