2006 volvo d12d injector problem

Same dealer everytime or was this last dealer different?

 

Did you try cleaning the soot our

 

I have A 2009 volvo D13 that has injector problem

 

Here is my main problem is m to 2013 kenworth t660 won't start with key

 

It will start if I cross and jump relays

 

Did any one inspected for leaking injector hares and going into ECU?

 

I'm wondering if the last placed didn't install something correctly....could be something as simple as a loose injector connector, bad injector harness etc. Because it happens under load i would gather its possibly degradation to the harness and your not getting full voltage to injector when it calls for it. Your going to have to take it to a good shop that understands how to do basic electrical really well and verify that everything electrical is good to the injector. It still could be the injector itself has an issue as the cylinder pressures come up but i would start with the basics before anyone throws parts at it.

MID 128 = Engine Control Module
SID 3 = 1/2/3/4/5/6 Unit injectors
FMI 5 = Open circuit in actuator circuit. Short circuit to battery voltage (injector high side). Short circuited injector (injector low voltage side). Short circuit to ground (injector low or high voltage side).
