1994 YJ 4.0 with 108k.

When engine off tach is at zero when idiling the tach stays at or below 1000 RPM. Upon acceleration, the tach doesn't go over about 1500 RPM even under heavy acceleration. Where can I go from here to get some tach action back for my jeep? Should I check a connection to the PCM and if so where do I find it? Does any one know if there is a connection to the ignition system anywhere else?
Thanks

I would trace the wire starting from the tach and make sure everything is ok. Then, if everything is alright, I would start looking for a used tach in the boneyard. Your tach could be shot!
