Injector code question
Just got my truck back Wednesday after having $1700.00 worth of work done on the motor. CSD sensor and also the injector pump replaced. This morning I cranked it up and after about 10-15 seconds, it make the most God-awful noise, shuttering, rattling, I thought it was gonna shake apart. I got it back in the truckport, and took the wife's suburban to the office. Came home after calling the dealer and took it in. It did not do it again, but the SES light was on. The service writer at Treadwell got it on a scope when I got it in. He didn't charge me a dime, but did clear the code and read it. They told me that the #2 injector had a "short" in it according to the scope. He told me that it caused the #2 injector to not fire and asked me if it shook and sputtered. I said yes. He told me that if it happens again, to shut it off and start the truck again. He said it was a 4-5 hour job to get into the valve cover and replace either the injector, the connector or the wiring harness. Anybody have any thoughts? I have the truck back and it seems to be running fine.

Check the electrical plug at the valve cover to see if it's plugged all the way in. If so, pull the valve cover and check it. Kwik posted some pics a year or so ago of the inner connection when his came lose.
Powerstrokeshop.com has a part to repair/replace the plug and they sell the entire UVC
I'd do this before paying to replace an injector.
I'll see if I can find KWIK'S old thread on this

it sounds like it may be a problem with the UVC (under valve cover) harness or plug pull the valve cover (drivers side) and check it out. the plug can come loose or the wiring can chaffe against something and short out (you will see what i mean once you get under there) oh and 4-5 hours to do the job???...lmao maybe if you didnt have thumbs

So, as I recall, this all started with the engine suddenly stopping when pulling out of the garage one morning... Ended up having the CPS and IDM replaced. Now you've got a no. 2 gone bad... Not being one to beleive in coincidences as far as mechanical things are concerned, I think you are still chasing the original problem. Like the guys have said, maybe a UVC wire or connector problem with no. 2... Since you are digging into the drivers side VC anyway, inspect the main wire harness that is secured to the bracket above the drivers side valve cover for wear where it makes contact with the VC. Take off the tubes between the turbo and air filter, look for the big connector held by a bracket on top of the VC. take out the screw holding the connector together, disconnect and inspect the wire harness. Got to take this stuff off anyway to get the VC off but you may get lucky and find the problem before getting the VC all the way off.
4 hours, yeah right, what wlihntr said... You should be able to have the VC off and your inspections complete in about 30 minutes or less.
Good luck with it.

Injector code question
Next Question,
I have located a local shop that is a diesel specialist. I am going to get an appointment with them and have them fix it. I know what to tell them to do, and they are not as high $$$$$$$ as a Ford store. Should I have them replace the complete wiring harness, I mean since we are already under the valve cover?
Just asking.

I think you have some ideas of what to tell them to look for... If it turns out to be the UVC harness go ahead and replace it. Be aware that you can pick the harness up on line, new, for about $50.
Might also want to install harness connector retainer clips while you're in there. Bascially they are little plastic retainers you add to the connector under the VC to keep the connector from rattling apart during use. Someone here can help you with a ford part #. Install the one for now and install the other side if you're ever in there. Don't know for sure but they should only be a couple bucks.

I'm not sure of your mechanical ability, but if you have just the basic tools, you can pull the VC and check it out in a few hours.
One of the funniest posts I've ever seen (on another site) said it best (although it was about the turbo) "remove all the stuff and bolts that hold it on, repeat this procedure until it moves freely about the engine compartment". It's about the best advice you can get. Look at it, there is some sheet in the way, losen it up, move it, and do what you have to do. There really isn't anything in there you can totally FUBAR. It is a lot cheaper than 30, 40, 50, 60, 70 bones/hour.

Injector code question
Coming back from church today, the "short" kicked in and the truck ran horrible. Should I?
A. Take it back to the Ford store and let them fish to fix it.
B. Contact the other place - injector specialists - set up a time and let them fix it.
C. Take one of you fishing with my boss and let one of y'all fix it in exchange.
Watcha think?

If you don't want to fix it yourself there are many places that can do this with much cheaper rates than the Ford House. Besides, it sounds like your current Ford shop has already been fishing around in your truck trying to find the problem.
We're all guessing it is an Under Valve Cover Harness issue. If your still unsure, have the injector shop or another mechanic you trust pull the codes. You can post the codes here and we'll chime in with more comments. Tell the shop you suspect the UVCH, and don't let them try and talk you into cleaning or replacing injectors until they get in there and find the problem.

Injector code question
Gentleman, you need to know two things:
First, I just looked under the hood and got scared. AIN'T NO WAY I AM GONNA TRY. It is important that I know my limitations. Second, on December 10, I am having a hip replaced. Not real mobile or limber. Although, you guys might be technically advanced, I an not. Your help has been invaluable.
Thank you
