Hey everyone,
I have a 94 Explorer, and one of the cylinders is not firing. Spark is okay (checked at coil, and at plug end of wire).
The plug itself was completely coated in oil and crap....we tried replacing the plug, but that did not change anything.
We did a compression test, 145 lbs.
So, the suspicion is that the injector is not injecting fuel.
Any way to test this without removing the upper intake manifold?
Thanks for your suggestions.
Chris
