Re: Buzz test -all passed, but Cylinder Contribution Test fails #3...
Well folks, since I work outdoors under a carport and it's colder than you know what around here and I had never attempted anything like this before, I decided that could not afford to spend too much time diagnosing the problem while the valve cover was off. My window of opertunity is small this time of year. Yesterday was low 20's here but today made it to 40 by late morning, so I decided to go for it. I needed to just get in and get out as quickly as possible.
I had purchased a Ford remanufactured injector from the PowerStrokeShop Friday and proceeded to change out the injector, inspect electrical wires and connectors. Thanks to all those who have contributed to this forum I successfully changed it out. The patient is alive and running as good as before, but that's the problem, it's running exactly the same. My problem remains the same, #3 fails the Cylinder Contribution Test.
Remember it passes the buzz test. Where do I look next?
