Powerstroke drops a Deuce

This morning while I was driving to work in my truck (I took it to work because I bought a used TV from a guy for my bedroom) the engine threw a fault (check engine light came on) and began running extremely rough, with very little power. I limped it to the gas station, thinking it was out of fuel. While filling up at the gas station I pulled out my tuner to scan for codes. Nothing. $100 in fuel later (3/4 of a tank, its still not full) I pulled out of the gas station and it seemed fine for about a block, and did it again. The scan tool still plugged in, I checked the codes and got "P1316 Injector driver module codes detected."

I limped it into the work parking lot, just before I parked it the CEL went out and it began running fine. I took it a look around the net and couldn't find any help on this code. I took it out a few times today and drove it around, and it is very sporadic. RPM, load, time operating, etc. seem to have no bearing on when it will act up.

I took it to the local Ford dealership (read: local Honda dealership that can order and service Ford vehicles) and asked to see a service manual for the truck. The counter dude went back to the shop, brought back 2 huge manuals and said I was more than welcome to look at them in the customer visit room. Having worked at a dealership in highschool, I knew right away that these weren't the manuals I needed. But I played along, went in, look through, and found that I needed section 3 of the manual, which neither of these contained.

I went back, explained that I needed manual 3 because these dont contain anything about the engine. He said those are the only 2 manuals they have, that one must be on loan to another dealership. I asked how they plan on servicing any diesel engines that they get in if they don't have the manual. He said they have them on a computer. I asked to see the computer. he said no. Fan-freakin-tastic.

So, I have enlisted my next option. I have a guy in my master's class that works for International, and I have asked him to look into it. He is still digging in, but apparently with the Ford scan tool you can tell it to scan the codes on the injector driver module. I might have to go back and have the friendly local Ford dealership scan the codes in the IDM. So for now, the truck is out of commission. With $100 worth of diesel in the tank.
