2002 2.5L. Headgasket/head rebuilt July 2019.
Since wheeling season around here ended in December the jeep has been sitting on its trailer and only been started once in February. At that time there were no issues and it ran normally. This past weekend it was pulled off the trailer in preparation for an upcoming Windrock trip and much to my dismay it is not firing on cylinder 4. I may be mistaken but this misfire occured only after the exterior and frame were pressure washed.
We have spark (visual observation with plug pulled) air, and fuel (pressure is good) but still no ignition in cylinder four. We did a pressure test this evening and got 190psi. The distributor cap got replaced as moisture was suspect and cylinder 4's fuel injector was replaced as good compression pointed us in direction of fuel.
The thing that has us stumped is that it is unique to cylinder 4. Any ideas? Thank you in advance.
Edit: the engine appears to be running normally on there cylinders. No hesitation, nothing out if the ordinary.
