Re: '93 GCherokee 6 Hard Start
Thanks Doug,
I did replace the O2 sensor last Fall.
Dealer advised of the gauge failing some time ago. Temp, sensor was replaced
in the Fall also.
Understand about the speed/cruise solonoid. That's for a later fix.
Going to be looking at the ground connections today. Wasn't there a Web site
or message on these locations?
I really appreciate all the help.

Lower mounting bolt for the coil. I think they switched over to a
ground cable so you might have one of those. If you do then you
should be fine, never seen one of them go bad.

Re: '93 GCherokee 6 Hard Start
Hi Doug, thanks.
Still no joy. The ground connections are cool as best as I can tell.
One thing I noticed just now. I removed the round plate/cover inside the
distributor to check if the pickup coil is gapped. The part with the 'vanes'
on it, wrapped around the dist. shaft, I think it might be called the
reluctor? Anyway, it rotates around the shaft. That doesn't seem quite right
to me. This is the thing that times the spark with the pickup coil right?
However, if it isn't supposed to rotate independent of the shaft, why would
my problem in not starting have increased in severity rather than just not
running at all?
As always, thanks for the ideas.

Let me get this right.. you took off the cap and rotor
then removed the two bolts holding the base in there.
The one in this pic.
http://members.***.net/wilsond/distr...d-position.jpg
The only electric bit that's in there is the CPS (Camshaft Position Sensor)
...not to be confused with the other CPS, Crankshaft Postion Sensor)
Also called the stator.
The stator should be fixed in position by a couple of plastic pins.
If these seperated you will get problems.
Here is what it looks like. (I made a new page) :)
http://members.***.net/wilsond/stator/
Actually the timing is set by the CPS (Crankshaft Position Sensor) located
on the transmission bell housing. The stator just provides a reference signal.
