Take the ignition module down to Autozone and have them check it. Be sure they run it on the analyzer a few times. My 92 ranger was doing the same thing and when I took the module down it passed the first 2 times then failed the 3rd. Bought a new one, installed it and the truck started right up.

I have done all that and even put a direct hot wire to the coil pack and still no fire I have checked the ignition switch and the relay under the fuse box I have checked about ever starting component even with a meter and everything checks out so if u can help me please do so ASAP and also put new wires from crank sensor and replaced crank sensor

The problem sounds like my 94 Mazda B3000, 3.0 L.(same as ranger). Tried replacing coil, ignition module, and would work for a while, but would begin not starting again. Had diagnostic done at dealer($100). It is the coolant fan relay needs replacing.Mazda Part # BTDA-67-0740 and only cost $12.00. It does'nt make since but it solved the problem.

Another thing to check is your crankshaft positioning sensor, a haynes manual will show you how to test with just a test light,
