Mine died at 9 years, 72,000 miles. It got very intermittant.

Have a CB? You should hear the pump for a second or two when you
turn the key. No pump noise, no start. The pump is $100 at PepBoys.

If you get it started, run as much fuel as possible out of it before
you attempt to drop the tank.

The last time I got it to start with the old pump, I had to click
the key 50 times. When I heard the pump in the CB (with the ANL off),
I hit the starter and got to my brother's house with his garage.

I only have third party keys for my 93 ZJ, the keys are just regular keys
they are not like the new anti-theft keys.
I would be looking at the CPS, fuel filter and engine ground strap.

Yes. Everything manufactured has a design life and for OEM Cherokee
fuel pumps it seems to be around 100,000 miles. Be happy that yours
fails to start, mine gave up the ghost on a section of highway running
through a crack neighborhood.

Yossarian, meet Snowden. Snowden, Yossarian. Yossarian here will be
dressing the wound on your leg.

There's the clue you should be paying attention to, not being lead away
by the red herrings of the battery cables (if it cranks you're already
carrying more current than the ignition will ever need) or the blinking
security light. If all the electrical accessories are working okay then
grounds are low on your list of things to check.

Based on my experience with my own Cherokee I'd suspect:

1. fuel filter
2. fuel pump
3. fuel sender in the tank.

In my case all three gave up, in that order, within a few months of each
other.
