Check Engine Light Cummins 300 ISC
I created this account on behalf of my dad, he has a 2011 Freightliner Class 2 truck with a Cummins 300 HP ISC engine. The check engine light stays on all the time, and the engine shut down while driving down the road. I've looked everywhere, and short of having it hooked up to a machine I thought I would turn to the internet. I know this is an RV site - but you're the most relevant forum that came up in my keyword search. I don't know all of the specs, but would it be safe to say this is likely a fuel injection issue?
Thank you -
