Power Steering Reservoir Cap

Electric Fan combined with washer fluid meth cooling on rad for towing.

2003 Dodge 2500 HO manual
I was on a road trip and my edge alert went off on the EGT. I lost power pulled to the shoulder and engine temp went up to 215. I let it cool down and tried to start it and all I get is the starter click trying to turn the motor over. I had it towed to my grandfathers and I can turn the motor using my barring tool. No leaks or low oil etc.
I finally got back this week to check it out and I get the following codes P2509 P0524 P2607 P0837. Batteries are good I checked cables and they look okay checked the connections and they are good. So I am thinking it might be the PDC but if anyone else has any suggestions on what else I can check I would greatly appreciate it. I am in the mountains so I have limited service and I don’t have my good meter to check voltages but I can do it when I get back. Thanks

With the symptoms given, my first guess would be a bad battery, electrical connection, or (very iffy) starter motor.

I don't recall if 2003 had it, but on the older trucks there was a single wire connector near the brake booster that I believe had a gray connector. That was the starter solenoid wire and you can jump B+ to it to crank the starter. That would rule out the PDC, but not bad batteries or bad wiring connections.
 
Thank you for the suggestions. I’m 300 miles away from where it is so I’m packing my tools and going to see if I can get it running this weekend
 
Well I got it started seems one of the batteries was shorted out replaced both so now it’s starting. Cleared out the codes and started it up only after about 15-20 seconds with oil pressure at 60 I heard a chime and then the pressure started dropping off I shut it down. Waited for a few minutes and double checked everything and started it up only to have the oil pressure drop off again and this time I let it run a bit longer than the first time and then the top end started to get loud so I am going to guess that the oil pump is bad. So since I need a new truck anyway I’m going to sell it for parts.
Thank you all for the help and advice I really appreciate it!
 
You are aware that the pressure gauge in these trucks is fake? It's today computer generated as the engine itself has only a pressure switch.

You checked the oil level I guess.
 
Assuming you checked the oil level as Ozy mentioned, I would also suggest checking the oil flow to the top end in the valve cover while it is running.
I had a similar issue with a 98.5 2500 pulling a travel trailer many years ago during a vacation to visit the youngest son and family at Tinker AFB, OK. A couple hundred miles from our destination pulled off to fuel up. Getting back onto the freeway, while accelerating on the onramp I heard a ding and noticed a red light illuminated in the instrument cluster. The oil gauge was way low. Then the gauge and dings went wild, swinging from mid-scale to low, and dinging up a storm. I pulled over and shut down. Checked the oil. It looked good, full and no indications of silvery flakes, etc. I got brave a restarted the truck. Initially it was back to normal, then all of a sudden it went into fits of wild needle swings and dings followed by correct indications. I pulled the oil cap off and noticed a full flow of oil to the top end, and no noticeable extra noise. So, I took a chance and decided to go down the road a little way to see if anything else would show up. It would go a couple minutes acting normal, followed by wild actions and dinging. I pushed on for the next couple hundred miles (AAARRRGGGHHH - 200+ miles with the lights flashing and dinger dinging!) and found a RAM dealer in OKC. It was the transmitter causing the issue. Darn thing was over $300 just for the transmitter.
