Need help guys my 06 cummins wont start without ether for the first start of the day after that starts on it own

 

Unplug the FCA harness from the CP3 and see if it helps you. Using ether is strongly discouraged in newer diesels.

You may have created an ether baby.

 

Check banjo fitting seals on back of head. Check fuel tube orings. Could be injector/s going out. Id check those two things first though.

 

Ill try it thanks So just unplug it for how long

Ok guys i need some help my 06 cummins wont start without ether if i dont use it my truck drain the batteries fast n if i use ether starts good n all day too could it just be my batteries

 

Unplug it then try to start if for the first start of the day and see if it helps. If it doesn't then plug it back in. If it does help you FCA may be going out.
