93 Grand Cherokee Laredo won't start
 

93 GCL (216k, Straight 6, auto transmission) won't start. All the
lights come on, open door bell dings, radio works, battery seems to
check out fine.

When I turn the key, nothing happens. The selenoid is not clicking and
the starter doesn't do anything.

This happened out of the blue....no problems starting prior to going
out this morning.

Any ideas?

Check battery connections at both ends. Check rear of head mesh ground
strap. Also try a jump-start. What does the battery voltage read?

Look at the battery terminals, and make sure they are clean... In other
words, clean them. They may "look" OK, but can have corrosion on the
terminal surfaces, causing enough resistance to keep from making good
contact. As far as the battery checking out, did you check it for voltage,
and put a load test on it? Recently, I have replaced the batteries in my
wife's little car, daughter's car, and son-in-laws truck. All showed 12
volts or more, but failed the load test. We have had a number of folks
coming to the auto repair part of our shop to have batteries replaced. Guess
it's the season...
Hippie
P.S.
My '93 did this yesterday morning at the Post Office for the first time,
but second try, it came on through and started. Cleaned the terminals, and
they were gray/black looking inside.

Lots. And one of them might be right too. :)

Before going any further, make sure you arm/disarm the
alarm system. Just in case the vehicle thinks your trying
to hotwire it.

Not turning over rules out the CPS sensor and ignition coil, so it has
to be in the cranking circuit. That's fuses/relay/wires/ignition switch.

fuses:

Behind the battery, in the fuse box, check the fuses. Especially
the 60A, and 40A ignition and 40A fuseblock ones.

relay:

Engine starter relay is the only one that can prevent the starter from turning.
You can swap it with a fog relay or a/c relay for testing.

If you have a volt meter.

Looking into the starter relay socket

^ -<---- should have 12v with key turned to start or run
|
`-all the time (fuse F12, 60A)

Sorry, crappy ascii art. :/

If it's not in the above let me know and I'll scan
in the relevant bits from the service book. That will
at least get you the schematic.
