I have a 91 wrangler like yours
with 4.0 5 speed. I wonder if you
could do me a favor. I lost all
spark to sensors and coil.
turn your key on (don,t start
egine) take harness loose from
crank position sensor and see if
you get any voltage thru the feed
wire. I,m not getting any. I think
I might have fried the computer. I
have 6 pins going into the
computer 12volts, but no output
signals or voltage.
