Miss Fireing one cylinder - Injector problem.

[mindy1701]

Hi All

My AHU seems to be missing on cylinder 3.
I compression tested the engine and all are running 450-480psi. I think it good since there all about the same.
The glow plug is clean for that cylinder and black for the other three.

Im thinking a pluged injector ?
Any easy way to test the injectors ?

I guess I could pull it out and run it over outside the engine. Might make a mess.


Thanks
Mindy

Does the car really seem to be missing or are you basing your judgement on the glowplug condition? If so, I would check the other three glowplugs for continuity. Glowplugs that are not working will build up a layer of black soot, while ones that work will burn it off. Good luck.
