Back up a minute...Do you have spark from the coil wire? (juice from coil) If so, change or check rotor and cap (wires do not all go bad at same time so unless they are wet, likely at least good enough to start engine)

OK...I have a 93 outside...one diagram I have shows an ignition module next to coil...but there is none on mine, (4.0 engine)
Two items to check are crank sensor and cam sensor inside distributor. Test procedure can be found in just about any manual including haynes.
You will need a decent volt/ohm meter to do testing. You can also check codes by turning ignition switch on/off three times, leaving it on the third time. Check engine will flash code #'s (ex: one flash, pause two flashes= the number twelve.then followed by a longer pause then another set of flashes etc.)

Sorry brother, it is in the gas tank with the pump. they used filters that are suppose to be good for the life of the vechicle. you can see the plug if you lift up your spare. hope you dont HAVE TO go in there.

If you have the V8 engine, the filter is actually part of the fuel pump. WHICH IS IN THE TANK
