As for fuel pump, why? Just based on mileage/years? I don't believe
this is the issue, so I'd like to hear your reasoning on why the fuel
pump.

Have you changed it's filter? We change regularly every twenty five
thousand miles on Fords, GMs, and Even the YJ Jeep designed by American
Motors Corp. Guess why?

ignition coil is possible, how old is it/the wires/the plugs.

Start by pulling the codes
http://revbeergoggles.com/engine_codes.html

It could also be the CPS (Crankshaft Position Sensor). That will cause
a no-start. By the dipstick (I6) will be a plug that runs around
back. Unplug and replug the plug. Then try starting again.

No fuel pressure or a clogged filter can cause your problem. So can
crapoline. How long has it been since you replaced the filter?

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.
