2001 Cherokee Sport 4.0 bad misfire

[Jeep77]

New to forum, need help.
Was missing on 1,2 & 6. Replace coil pack, spark plugs and still missing on 6. My mechanic checked, compression, vacuum, fuel pressure, injectors and added 44k to the fuel tank. Everything looked good but still bad miss on 6. He thinks it could be a bad coil pack, cam sensor or crank sensor.
Any suggestions?

Swap the #6 spark plug from a cylinder that's NOT misfiring. If it follows, re-check the gap or replace. If it doesn't follow, have the mechanic check the valves and valve springs.. As for the cam and crank sensor, hitting a misfire at a particular cylinder is not likely. I would consider looking at the tone wheel for any obstruction, mis-alignment or damage.Coil pack is still a possibility though.

We swapped the #6 plug but the mis stayed on #6. It's not getting any fire at all to #6. I'll pass the info about the tone wheel along to my mechanic. I don't even know what that is.
