So, the other morning I went to the store, no issues. I tried to start it a couple hours later, the truck would crank but it did not start. Found the P 0113 code and located four burnt spark plugs out of the eight. They were only 2 months old, pulled and cleaned all fuel injectors and tested them, checked the mass air flow sensor and IAT sensor, which they're combined. Also checked wiring between mas and ECM wiring harnesses to ensure continuity, also checked vehicle grounds. Removed and cleaned all grounds and reinstalled, went to crank the truck. Still no start truck throws p0630 code and battery is extremely weak now from cranking and testing. I'm in a bind and need help.

The problem is the p0630 code: Here is what is said:

A P0630 code is a diagnostic trouble code (DTC) related to the vehicle's VIN (Vehicle Identification Number).

I would remove the PCM and install a rebuilt unit you can find by searching google or eBay here is the location of the PCM which is next to the battery, you will need your VIN number. Check out the images (below). Please let us know what happens.

It threw that code once and not doing it anymore. But the truck still won't start. I will look into this more and get back to you. Thanks

It's strange because no P0630 anymore and another P0113 code pending and another one confirms.
