will not start any ideas?

Wife drove durango and said the engine light came on then went off, came home and parked it. The next morning it turns over but will not start. I turn the key on and can hear the fuel pump run, sprayed gas into throttle body = same thing, no start. I put a spark indicator between # 1 plug and coil = indicator does not light up. I checked the cam and crank sensors they look to be fine as does all wiring and grounds. I ohms tested all 8 coils and all are within .6 to .9 ohms. I checked the input voltage to each coil and got readings that range from 4.7 V. dc to 24.1 V. dc ( I can't find any specs on that voltage? ). With help I decided to change out the PCM = No change. I then replaced the crank sensor = No change. Battery is good with a full charge. I am out of ideas, cam sensor? I don't think it stop eng from starting? any other ideas??
