So I finally took my truck in and got it diagnosed and the Contribution test had #'s 2 and 4 failing. He suggested I check the wire harness for burned wires or connections. Did that and everything looks good. I did a compression test by removing #'s 2,4, and 6 glow plugs. I started with #2 and had the engine turned over it showed 25 lbs #4 showed 45 lbs and #6 showed 150 lbs. Understand that this may not be the best way to test, I read about testing each one with the engine running so I will do that here shortly. Regardless of what the next test shows the 2 cylinders are obviously low on compression, so whats next? Pull the heads? Different tests?
Thanks
