Hello and am learning
I read the EPB sensor problem and this may explain some of my problems with engine shutdown at idle, sudden surges at idle and highway speed. Are there any recalls or computer updates available for my 2004 6.0. I also have an electrical problem with my batteries going dead overnight. You never know when this will happen. Sometimes daily, sometimes weeks. I am going to get an EGR flush as soon as my oil needs changing. I am almost convinced my problems are electronic as my transmission went into fail mode last Saturday during one of those engine stutters. It would not shift out of third. I recharged the batteries and the problem has not re-occurred up to date.We had the batteries checked as well as the alternator and all is well. We concluded there may be a parasitic draw. I somehow still suspect the alternator. I put my hand on the alternator early in the AM and it is warm, and the batteries were at 7%. When we disconnected the batteries at the shop, and I think he cleared the codes, the truck ran like a scalded dog, the turbo was more audible and the dually barked the tires going into 2nd. Any ideas?

Thanks for the welcome
I probably should have been more cordial instead of jumping right in to complaining. I think I might like this site. I am disappointed in this truck, but hope I can work out the bugs and enjoy it more. I have heard nothing but bad things about the 6.0 and hope they are not all true. I would think that if there were all these problems that Ford would have had to correct them. The boss at the machine shop where I work builds hot rod engines as a hobby while we slave on the money making projects. (Not really) He is just not into diesels. It really is a great place to work, and I am grateful for the employment.

Are you the original owner?
If so, when did you buy the truck?
How many miles on the truck?
When was the truck built (date is on the FICM - Fuel Injector Control Module)?
Has it ever been reflashed?
Have you had it checked for codes?
You need to get to the bottom of the charging/electrical system issues. They will cascade into other expensive issues (like FICM failure).

Answer to questions.
I am not the original owner. The truck has 89000 miles on it. It is a 2004 model on the second engine. The engine was replaced prior to my purchase. (I did not know this until I had the transmission replaced in 2006) All under warranty. I am not familiar with the term re-flashed but it sounds like computer. And am not sure where the FICM is. DOM on door post is 07/03. They said they had to re-program the computer when the transmission was replaced.

Your 2004 truck (apparently built in 2003) originally had issues with bad EBP sensors. To fix it, Ford came out with a re-flash (Re-program) of the PCM so that your control strategy did not need the EBP input. This is why I asked about build date and re-flash. Since you have a new engine, I would assume it came with updates, including a good EBP sensor, so that the engine install came with a new programming mode for the PCM to now use the EBP sensor. I AM JUST GUESSING THIS THOUGH - MAYBE A TECH WILL JUMP IN AND CLEAR THIS UP.
I do not know if your engine is still under warranty or not. Maybe a call to Ford would clear this up for you.
I will post a pic of the FICM. It would be good to see the date that is on it.
Quite frankly, your problems sound electrical OR ICP sensor (Injection Control Pressure sensor). You can check this by unplugging the ICP sensor and seeing if the performance improves. this is really just a test mode.
Anyway - be sure to track down and solve the electrical system issues ASAP.

You definately have an electrical problem. I would charge the batteries and have them load tested to see if they are good. These trucks seem to be hard on batteries. I would also have the charging system checked out. If the alternator is warm on what I'm assuming is a cold engine, I would highly suspect an alternator problem. You can hook an amp meter up or get the kind that are placed over the cable and see what the draw is. You then can start pulling fuses and relays until the draw stops. Then you have the circuit isolated that's giving you problems and can service accordingly. Bad batteries do make these newer vehicles do weird stuff. And a bad battery can take out a good FICM.

Sudden surges and batteries dying overnight points directly to a wiring harness problem which these 03/04 trucks were known for. If you search in the tech folder at the beginning of the 6.0 forum you'll find some information posted by Bismic (THANKS MARK) that is titled NO START ISSUES which has information on common wire chaffing spots. Some of them are VERY hard to spot. Disconnecting the batteries can make the tranny computer go into "relearn" and the shifting will be fairly crisp for a day or two. I have heard of alternators having internal shorts causing the batteries to be drained, but I'm no expert there.

Possessed truck
As per the battery drain problem, I have been monitoring the my test light every evening. I disconnected both negatives and put a test light between the neg post and neg term on the passenger side, the light stays on for a short while till the computer goes nite nite then it goes off. The hood is still up, doors closed. After being asked by one of you guys to check the date on the FICM, I went out to the truck at 18:38, opened the door to get a date off the door post, shut it an noted the test light came on. Went back inside and waited for the light to go off. At 19:02 the light was still on as well as the hood light. I opened and closed the driver door and the hood light went off as did the test light. Am I close? Is there a possible sticking relay?

Is your truck equipped with Security Package or convenience Package? Your lights off delay goes through the Generic Electronic Module, or GEM. There might be a problem with the module or the circuits it controls. The only way I know how to diagnose exactly what's going on is by following the dianostic tree in the powertrain and emissions control shop manual. In the absence of having the manual, you can begin the process of pulling fuses until the problem diappears to isolate the circuit. If it's the GEM itself that's bad, then this won't work. The Powertrain and Emissions manual will get you there faster and tell you if it's the GEM if certain conditions aren't met during testing.
