I have an 85'CJ7 which I am restoring. Six cylinder with 4 speed. It
has been running fine. I am stripping it down completely, and I
pulled the guages out of the dash so as to get a good paint job on the
interior. When I tried to put the Jeep back into the garage it would
no longer keep running. It will start but as soon as I release the
key, it dies out immediately. The only way I could get it back in the
garage was to keep pressure on the key in the start position and back
it up a few feet while turning the engine, starter and all. I did
pull the tach out - would that break the run circuit - so am wondering
if I just need to replace it and then try. Ignition shot? I really
didn't put any undue pressure on anything, but maybe I pulled a "run"
wire out or broke it or something like that. Any ideas, please, would
be helpful regarding possible cause and easy checks. Thanking you
all in advance. Dan

It is the tach.

On the Laredo, the tach is inline with the run power for the ignition
module. You can just plug the two plugs together without the tach in
there.
