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?
