Injector Issues
I finally got my hard starting problem fixed and now I come to ya'll with a new problem. I was pulling my horse trailer yesterday when my 99 F350 started missing and the "Service Engine Soon" light came on. I noticed that the truck wasnt smoking ,never really has, and all of my gauges maintaned normal opperating ranges. I have a super chip tuner so I plugged it in and downloaded the codes and found that I have two, first is p0603 and the other is p1316. I reqad that the p0603 is a faulty injector circuit and the p1316 is a KAM error. I have no idea what the KAM error is so that would be my first question. I have been planning on upgrading my injectors for a while so this isnt a bad thing as long as this is truely the problem. My second question is of opinions, what are the best performance injectors out there for the money???

Isn't P1316 the Injector Driver Module code? I need to go look it up to verify.
.
If I am correct then, by far, the most common cause of that code is a loose wiring harness under the valve covers. They tend to come loose from the inner plug and it's a simple matter of removing the VC's and reconnecting everything. Or if it's rather loose, then just get new VC gaskets and wiring harnesses. If you go to your local International truck dealer and ask for a set of valve cover gaskets and inner VC wiring harnesses for a 2000 T444E engine you will have the correct parts for your engine for a lot less than you would have to pay at the Ford dealer for the exact same parts.
One loose plug in that harness will set the code for the P1316 and send you on a wild goose chase more often than if the IDM actually failed. (Personal experience talking here.)

Thanks Kwikkordead,
I looked it up again and the code P1316 Injector Circuit/IDM Codes Detected. And the other code shows a missfire on #6 cylinder which would make since. How would you test the #6 injector?

If you don't have good access to any of that, just take the time to remove the driver's side valve cover and look for plugs working loose. In and out it's about one hour going slow and using hand tools.
If you have a shop with air tools: 20 minutes.

I have already removed both v/c's and found no loos connections. I just now did an ohms test and the gasket looks to be good as well as the connections. Is there any other place that you can think of that would cause this same problem without it being the injector?
Thanks a bunch

My vote is a bad injector.

Kwik, where is the best place to install the EGT sender, in the manifold or pipe just before turbo? Also should I weld in a fitting or just tap the hole?

Here's the best place with pre-turbo. Drill a small pilot hole, then use a R sized drill bit ( i believe .357") for an NPT tap, and i believe a 7/16" hole for a 1/4 NPT tap.

Truck runs great after sorting out some minor codes that popped up. I installed the Alliant stage 2 split shots because the singles in the stage 2 & 3 were on back order for who knows how long. H2E? I am unsure what this is so please enlighten me. But I just cant get over how much power these things can make with such minor modifications. I am still used to building gas engines and having to deal with all of the fine tuning to get the most power.
Thanks again
J

You said you upgraded the turbo too. You bought from the wrong place if single shot stage two's are "backordered".... Curious, where did you get them anyway? The H2E is a popular turbo, next step up from the stock one. Can be modified to a wild turbo though. Made by Hypermax.
