Filled up with diesel drove home ran good started it up in the morning drove about 5 miles and turned a corner and all at once started running really ruff,had no power acts like a fuel issue changed the fuel filter still runs the same no codes and ses light not on any ideas ?? Any help greatly appreciated

 

Check the UVCH

 

remove connector to passenger side injectors and see if it runs the same


if it dies try other side and if runs the same then you know a bank is out


Fuel pressure?
tanks full or at least 1/2 full?
any leaks?
getting any boost?

 

Check the valve cover harness and plug ins for burned pins. With it running unplug one plug at a time to see if it runs any different.


Edit: you guys are fast.

Thanks I will try all when I get off work

 

Just slow, lol.

 

Ok I unplugged the wires on the passenger side and ran the same unplugged the drivers side front and killed it so seems to me none of the injectors on the passenger-side are working

 

Sounds like you got bad uvch Causing the IDM to shut down that bank of injectors.
If the IDM detects a short in the uvch it will shut down that bank to protect it self. You can either ohm the uvch or pull the valve cover

 

Thanks for the info how would you ohm the uvch

 

You ohm the pins on the valve cover gasket.
Pin layout is

GICIG
G - Glow Plug
I - Injector +
C - Injector -
Ohms between the G and block Ground should be 0.1 - 2.0 ohms.
Ohms between the I and C one at a time if one or more is > 4 ohms, it will point to the side's gasket connector or UVC harness being shorted.

 

Thanks I pulled the valve cover and one of the plugs were melted and a glowplug wire was burnt in half so bought a new gasket still doing the same thing

 

Did you replace the pigtail as well? Also did you inspect the under valve cover wiring. Check to make sure all the clips to the injectors were in good shape and secured properly?

 

Yes I did change the pigtails also and came with new under valve cover wiring.
thanks

 

Ohm them from the outside of the valve cover
