Re: 90 XJ troubleshooting no start problem
No, there is a unit that more or less replaces the points inside the
distributor. I don't have the meter reading to test it. Maybe someone
else has them.
MY ground strap was on clean and tight, it just had no metal left in it
to conduct. It crumbled to powder in my fingers.

Re: 90 XJ troubleshooting no start problem
I checked all the electrical connections today and the grounding straps... a
little rust but I tried to make good connections again with some wd40 and
sandpaper. Checked that the coil was getting 12 volts and even brushed up
those connections. Now it has cranked and is running fine. Guess it was
rusty/grimey connectors. Thanks for your help everyone!

little rust but I tried to make good connections again with some wd40 and
sandpaper. Checked that the coil was getting 12 volts and even brushed up

rusty/grimey connectors. Thanks for your help everyone!
