It could be your filter is clogged, there is a clog in your line. It could be the fuel pump, could be nay number of things to do with the fuel system, or not at all.
Check all vacuum lines and make sure they're attached/not broken or cracked.
Check the airfilter and the intake hose to make sure it is free and clean.
I assume it is carburated, so if it won't start try pouring a LITTLE bit of fuel into the barrels and start it. If it starts and runs for a few seconds then dies out then you have a fuel line issue.
You can use the accelerator under the hood to do this.
If it starts but runs hard and sputters it might be a vacuum line leak. If you find/see no visible breaks int he line sets then try spraying carb cleaner/brake cleaner around your vacuum line connections and air intake etc. If the motors rpms increase you've found a leak.
If any of my suggestions work, then I'd go ahead and replace the fuel pump (if that was the problem), fuel filter, do a fuel injection clean, spray the MAF, Idle Air control, and intake with carb cleaner and cross my fingers that I'm okay for another couple thousand miles.
IMO, a 96 Explorer isn't a very reliable vehicle and you'd be better off selling it and moving on to a newer model with less mileage.
I hope some of this helps.
