Cylinder drop test shows # 4 dead/not firing
Compression is 125 across all six
fuel press 104-106
air press 92-94
With scan tool I've tested air/fuel injectors, and coils
To be sure I've swapped out, one at a time, the spark plug, wire, coil, and fuel injector with #4 no change
no trouble codes
Spark plugs on port side seem to be a bit wet with fuel compared to starboard side
Do to limited tool supply I haven't checked the reeds, tracker valve, or any other diaphragms in the rail.. Yet. I hope to this afternoon.
Over the winter I had my fuel/air injectors cleaned, I installed new Chris Carson reeds, new thermostats, oil lines etc.
Would a busted reed or a bad tracker valve toatally kill one cylinder?
Any other advice or input would be much appreciated. Thanks
