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.

Shift it to neutral and try again a couple of times to see if it's

Re: 93 Grand Cherokee Laredo won't start
 

Same thing happened in my dad's Grand Caravan earlier this summer. He
got it towed to the dealership and found out that his computer (ECU,
ECM, whatever you want to call it) had just up and fried. I've never
heard of it happening before and didn't think I'd ever see it happen
again, but the symptoms described are exactly the same as what was
happening... all cabin electronics working, but when the key was turned
to ignition, absolutely nothing happened.

Re: 93 Grand Cherokee Laredo won't start
 

also should have noted that it happened exactly the same way, he was
driving home from work, stopped for dinner, got back in the car, and it
wouldn't start.

2 weeks after he got it fixed, though, it did the same thing and he
found out that his alarm system was doing it. He didn't even know he
had an alarm system. So check that first, it'll be a lot cheaper to
fix.

I don't believe this vehicle has an alarm. How would I arm/disarm the
system (assuming it does have an alarm)?

Re: 93 Grand Cherokee Laredo won't start
 

No starter could easily be a bad connection. If you try it a few times,
then 'carefully' go feel the battery cable ends, you might find one
hot. This hot one will be the bad connection. Careful because the bad
connection can be hot enough to burn you.

The starter could have quit. You can take a hammer and give the starter
a smack. If it then starts, the starter brushes are worn out. You can
replace the starter or just the brushes if soldering doesn't scare you.

We actually fill the starters with mud around here which jams up the
brushes. Then a can of WD40 is used to clean them out on the bench and
away they go again.

Re: 93 Grand Cherokee Laredo won't start
 

No starter could easily be a bad connection. If you try it a few times,
then 'carefully' go feel the battery cable ends, you might find one
hot. This hot one will be the bad connection. Careful because the bad
connection can be hot enough to burn you.

The starter could have quit. You can take a hammer and give the starter
a smack. If it then starts, the starter brushes are worn out. You can
replace the starter or just the brushes if soldering doesn't scare you.

We actually fill the starters with mud around here which jams up the
brushes. Then a can of WD40 is used to clean them out on the bench and
away they go again.

If it has an infrared key fob, you just lock/unlock the doors.
Also turning the key to unlock in the driver door or tailgate will
disarm the system.

If you press lock, then shut the door, is there a SECURITY light that
flashes on the instrument cluster. If there isn't one then you don't
have an alarm. Sometimes you can tell by looking for the little black
bubble that is in the overhead console or between the rear passenger
overhead lights.

Re: 93 Grand Cherokee Laredo won't start
 

Thanks for all of the suggestions.
I cleaned the battery terminals. They were not very dirty and cleaning
them didn't help.
The car does have the bubble up near the overhead light however, I've
never seen it blink. Also, there is no dash security light...so, I
don't think it is the alarm system.
There are a couple of other symptoms:
#1. For quite some time, I have had problems removing the key from the
ignition. It won't turn back to the point where it can be pulled out.
Usually, after a few back and forth attempts, the key will come out.
#2. I've also noticed that when the key does come out, the steering
wheel does not lock.

Do either of these things sound fishy...perhaps a neutral safety
switch?

I've pulled the started and I will take it in tomorrow to be tested.

Thanks again.

Re: 93 Grand Cherokee Laredo won't start
 

#1. For quite some time, I have had problems removing the key from the

ignition. It won't turn back to the point where it can be pulled out.
Usually, after a few back and forth attempts, the key will come out.

You may want to check the key cylinder and make sure it didn't break
internally. Does the key go to the run position then spring back as
normal? If not, that could be your issue..you'll need a T20 anti theft
torx to get at it, but that is all...oh disconnect the battery to let
the airbag discharge.

Re: 93 Grand Cherokee Laredo won't start
 

Okay, I think I got it! Had the started tested, it was okay.

Brought it back home. Went to put the starter back on and noticed that
one of the mounting bolts was stripped out....and, it seems that bolt
is necessary for a good ground!!! I replace the bolt, used some thread
lock, and it starts just fine.

I also replaced the key cylinder on the ignition. $51 and about 1/2
hour and the new key seems to work just fine now. It was pretty
easy...I should have done that a couple of years ago!

Thanks everyone for your help.
