So how can you tell if you have a bad injector? What symptoms would you have.
Yep, that's what mine did when injector #6 went.FICM voltage holds at 48.5 starting to running. Started truck at 67 degrees this morning was fine drove less than a mile EOT was about 160 stopped at a stop sign truck was shaking. Accelerated from stop you could fee the motor hesitate. Has been that way all day.
Good to hear that it was just a loose connection! :thumb:Well I just got lucky. Since the truck cooled down I went out and and checked the connections to the FICM and the injection harness. I found one of the metal clips for one of the injectors was gone. Fired the motor up it was rocking the truck. I figured why not take it off the injector while running and see how bad it would run. Well pulled it and the motor was rocking the truck but no worse. So now I know how the motor is with an injector not firing in a closed position. Now I plug it back in and it runs better then back to rocking the truck. Well I figure there must be the bad injector so I played with the connector a little and found if it tilted it to the fire wall it would cause the motor to miss tilted it to the radiator and the motor ran smooth. Well shoot put the clip on the harness to the injector now it runs fine.
DEESLVRGN I would look at getting an new injection harness. Check to see if all the silver metal clips are on the the connectors that sit on top of the injectors first.
Just info. I have the blue spring in the FPR and I run Fords cetane boost with TCW3 2 stroke oil. Rotella T-6
