We have a 1992 Ford Explorer that has 180,000 miles on it. It stays
parked in a storage lot and is only used to tow our small boat to the
lake nearby,,,so it is used very seldom. We do start it and run it for a
few moments every other week and have never had a problem with it until
last week when we tried to start it and it wouldnt start up. It cranks
fine but does not fire. It is a 4.0 V-6 with a manual transmission. We
even tried jumping the battery and the engine just cranks fine but does
not fire up. There is gas in it. Any ideas?

You need spark. Pull a plug out and look at it when you crank. Is it
firing?

You need gas. Does the tailpipe smell like gas? Is gas getting into the
cylinders? Odds are if it has been sitting that the gas is full of
thick and gunky varnish, unless you normally keep fuel stabilizer in the
tank. Is there pressure at the fuel rail? Is the fuel filter a solid
block of goo?

Scott may be right, the fuel filter may be blocked.

Just starting the vehicle but not moving is really not the ideal way
of doing it. It is better if you start the vehicle and take it for a
little short ride.

I'm coming in here a little late, but if it's cranking over and won't
start, I would check the fuel pump disconnect switch usually located
in the sidewall or under the upper mat near the passenger's right
foot.

Check the owner's manual for details on the switch location. You can
download an owner's manual from the official Ford site.

Its purpose is to shut off the in-tank fuel pump in the event of a
wreck to keep fuel from being pumped into the wreckage. I dunno how
hard the vehicle has to be hit to activate the switch.
