died after starting

Ok I posted this in the 6.o area but got no replies .

Thanks in advance for any and all help.
Truck is a 2005 f250 4x4 with 6.0, 64000 miles, pure stock, I have owned for about 3 months. Truck ran fine 2 days ago (150 mile trip)
Went out this morning (36 deg) to start and warm truck for the day. The truck started like normal, ran about 5 sec and knocked off. Tried to restart, acted like battery was low. Dealer had replaced pass. side battery before I got truck (850 cca). Drivers side was factory original. Pulled both batteries, went to Interstate, test batteries, factory battery bad, other one was good but low charge. Get new 1000 cca battery. Installed both batteries, put charger on old one. After charging 2 hour, truck will turn over sluggish but not start. When trying to start, oil gauge will twitch but not move up.

I am not a big wrench turner, but I like to try to fix what I can. So what are simple things I can try or does this sound like a trip to the shop?

After looking at different post this is what I have done so far- Check batteries both have over 12.5 volts, Pulled and clean EGR valve- some build up but was not stuck open, Checked FICM volts- steady 48v.

Again when trying to crank it turns over very sluggish, like it has a low battery.

What other things can I check. I don't have a code reader and don't think I can put the money in one right now.

Any help would be great.

Check battery terminals for corrosion. If you don't have a good connection, it doesn't matter how big your batteries are, it will not start.

Terminals were cleaned when I pulled the batteries to replace. After reading a lot of other post, I am starting to think it may be the High Pressure oil pump. I just want to try all the thing that I can before having to take to the dealer.

Well, the shop just called. The a/c compressor has locked up keeping the belt from turning, which keeps the motor from turning over. In the process of trying to crank it, the started is about fried. They pulled the belt off and it started up, but could tell the starter was dragging. So, $1200 later I should be able to get my truck back Friday, maybe.

I had the same problem and I replace the STARTER motor and from then won't have any more starting issues.

Well, new compressor and starter and $1200 lighter, the truck is running fine. Now to build up the cash fund to do the coolant change over.

Wow, weird that is was your AC. My 2005 with the same miles died 3 weeks after doing the Exhaust gas cooler delete and new uppipe. Was the high pressure oil pump valve. Part was cheap but the labor was a duplicate of what had been done 3 weeks previously. If you are doing the delete, make sure they do the oil pump valve or a whole new oil pump.
