Ideas truck shutdown
My dad was heading home and truck just died. Has 12v at shutoff solenoid filters are good has 50-60 psi cranking on onsite 10-15psi when electric is running. Had codes for cylinder imbalance, and low fuel pressure moderately low. And I believe 1943 unknown code. 2007 t600 cm870

RE: Ideas truck shutdown
Did you spin the filter off? Was it full of fuel? If not, maybe sucking air? fuel(gear pump) bad? I think that cylinder imbalance is pretty common on a demandated 870

RE: Ideas truck shutdown
Fuel pressure is low while cranking. I think you need closer to 100 psi minimum to start.

Cylinder imbalance is very come. I get it at every filter change and random times. Its really nothing to worry about unless its really rough running.

She also has 1.4mil on pump so it's time most likely
