Sounds like the distributor rotor isn't turning. Remove the distributor cap but leave the plug wires on it, and set it aside. Remove and inspect the rotor. Put it back on if it looks undamaged. If you can view the rotor while cranking the engine over (get an assistant or rig up a mirror if that isn't possible). If the rotor doesn't turn while cranking, there are several possibilities:
The timing belt (if equipped) is shot
You have a broken timing chain (if equipped)
The timing gears have very worn teeth.
The distributor drive gear is worn out.
3.0 V6 Ford engines are bad for wear on the distributor drive gear as well as the "adapter" that couples the dist. drive gear to the camshaft. On this and many other engines if there is no rotor spinning then the fuel pump is cut off from a lack of ignition triggering. Ford doesn't provide a means to lubricate the adapter and distributor gear so they wear out. A poor design in my opinion. They recommend a new Cam, Cam bearings, distributor adapter, and distributor.
You didn't mention what vehicle this is for, or what engine type it has.
I owned a 75 Chevy wagon with HEI ignition and liked to never found the problem. It seems under the center contact on the distributor rotor would get a hole burnt in it, and then all sparks go straight to ground.

Pick up a spark tester (it'll cost under 15$) . After installing the tester on one of the 2 rear right or left bank spark plugs, have someone turn the engine over and check for spark. If you have no spark, you could have either a broken timing chain or a broken cam-shaft. The only other minor item you didn't mention with regard to the ignition system was to make sure you have a good hot power source to your distributor. If these things don't work, it might be time to check that the carburetor or throttle body fuel injection (as applicable) is providing fuel.

IS IT THE 4.0L?IF SO U MAY HAVE A BAD CRANKSHAFT POSITION SENSOR.
SOURCE: cut off while driving replaced fuel relay switch,
sounds like you have an electrical problem, get a diagnosis, and see if all your fuses and everything are all getting power, and if they are, then try replaceing the rotor on the distributor cap
SOURCE: 96 ford f150 5 l engine, replaced pcm twice,
ecc and fuel pump relays good? when the engine is turning over, does the ck engine light go out? if not the PCM isnt getting a crank sensor signal. Power and grounds all ok at pcm?
