Ok, today I started by truck up and it runs rough. And my engine light comes on. I went by auto zone and there code scanner doesn't come up with anything. There is a sweet spot at like 50 or so, and it will run normal. I am going to swing by advance in a bit and see if there scanner comes up with anything. I have read a little about the connector under the valve cover coming loose. Were should I start first. I need to get it running right asap, as it is my daily driver. Oh and its a 02 f250 with the 7.3l.

You need special scanner to pull codes off Powerstroke.
You could pull off oil fill cap and smell in the valve cover for burnt wires. If you smell burnt wires then you have burnt harness. even if no smell you could have loose connector under valve cover

Ok, I am off to pick up a superchips flashpaq right now. Its about an hour from me so I will be back to test it in a couple hours, I will post up whatever code(s) come up. Anything else I should pick up while I am out? I have a good feeling its going to be those UVC connections. Thanks for the help.

You could ohm out your glow plugs at the 9 wire plug on the valve cover. This would give you a good idea whether or not the uvc came partially unplugged. When you get the tuner read the codes and record. Then clear and see which ones come back.

Ok, I just tried to go get the plug. And my truck started running even worse, big loss of power, and at times sounded like it was going to stall out. I only made it about a mile and I limped back home. My buddy is gonna take me to get the tuner. I will keep you guys posted.

I am located in clermont, fl. But I just got back with the tuner. And it only has one code p1316. Which I guess is associated with the under the valve cover harness. So should I go ahead and pull the driver side valve cover and have a look? Is there anything I should do before that?

Thanks

The 1316 means there are codes stored in the idm and would have to do a buzz test to retrieve. Usually this is caused by a uvc that is unplugged. I would ohm out the glow plugs while I had it apart. What makes you think it is the drivers side? That side is definitely the easiest to do. Some of the bolts in the back are hard to get to. Might need 1/4 ratchet and various swivels. Might want to get a new valve cover gasket it has the updated clip that is not suppose to come unplugged. They also sell clips that you can put in to keep it from coming unplugged. If you have an international dealer close that would probably be your best bet for the gasket. Good luck.........

No international dealers close. I am pulling the drivers side valve cover now. Hopefully it is that side. Were else could I get a new gasket? The gasket comes with the clips? Could I get it at autozone or napa? If not there is a ford dealership close. Would any of those places have it in stock? Also is there anything wrong with running the truck with the valve cover off to test if it worked or not? Obviously I would have to leave the boost tube off to. Let me know what you think.

Wow, you are doing some late night work if you are in Fl. You can run the engine with it off but if it is unplugged I don't know if I would bother. You can also tie wrap the clip. You'll see when you get it all apart.

Zip tie under the clips at the connector. Just make sure they can't move and allow it to come loose again. Are you supervising?

Oh, no. I am here alone. I have an motorcycle/atv parts business. So I have a computer in the shop. My truck is like 10ft from me now as I type. Only thing is my key board is covered in grease. Well I just started it up with the valve cover off and it runs great. So I will zip tie it down, and put it back together. I guess the one good thing is now I have a tuner to play with.
