6.0 Headache After Turbo Recondition

[rocky1074]

Truck was running with no power (Turbo farts on acceleration and deceleration; lots of black smoke;with no power) I pulled the turbo as posted removal & installation. I recondition turbo as per diesel technician society. Upgraded the oil supply line and oil drain tube. Installed new ICP sensor and pigtail. Reinstalled everything check and double checked everything went back together perfect. Started truck and runs like crap. Runs like a 8 cylinder gas engine running on 5 cylinders. Truck is shaking and running real rough with no power. Check all the connectors ect. FICM and Degas where removed also for more room in removing the ICP. Don't know where to go from here. PLEASE!!! I can use all the help I can get. Thanks

Ok this is all new to me..What are the UVCHs ???

[jesilvas]

Under valve cover harnesses. It's all the wires that run into the valve covers and supply the power to the injectors.

I just pulled aff the intake and degas to get a better look at all the wires. I checked all the wires go to the injectors and FICM. Checked all the injector caps coming out of the valve covers everything looks good and no cracks on the caps all clips on on and holding tight. All 3 plugs going to the FICM on attached. Don't see any wires the are bare from rubbing or dried out and cracked

Ok Jesilvas, I found the last plug toward the rear of engine was not locked into the FICM. I pushed all the way in and I heard the snap lock in. The front plug I found the clip that locks it into place was broken before I first took it apart. The tech that worked on my truck under warranty most likley broke it when they changed out the ICP Sensor 2 years ago. I wraped a long zip tie around the back of the plug and around the FICM. It will hold for now. Don't know if I can purchase a new plastic lock or have to replace thr entire end with all the wires. Well anyway I glad to see guys like yourself taking the time out helping us. Thanks again for all your help.

Well I do what I can but when it comes to 6.0s, I'm pretty much clueless.

You said it, not me. LOL

For future reference - there is no conventional UVCH on a 6.0

each injector harness comes through the rocker case on top of the cylinder head.

Learn something every day, hope this is useful information for you in the future.
