I have trouble shot and can not find the cause for getting NO spark and no power to the Fuel Pump. Anyone know of the reason or had this issue any help is appreciated! It is a 1997 Dodge 1/2 Ton 5.2 Liter Truck. Run a snow plow business and need to get it fixed ASAP!

Have you checked all fuses under the hood in the power distribution box? Did this happen all at once?

Yes and Yes, thinking it could be the box? I can replace that if needed

It could be a few things. It could be the ignition switch, the PCM, or it could be an issue with the auto shut down (ASD) relay. If the relay is bad or has received a signal from the logic module that there is a problem, the ASD will shut down power to the ignition, fuel pump, and injectors. From about 1990, the ASD relay was in a plastic underhood relay box at the left fender well. Check that and let me know what you find.
