2010 Fleetwood Discovery no power

I have a 2010 Fleetwood Discovery that just shut down going down the road, motor turns over but will not start. Fuel filter and pump are fine as well as the ecm. Any thoughts?

As diesel runs on air and fuel, so it's got to be one or the other. There is no "ignition" to fail.

How do you know fuel is reaching the injector pump? And that the pump is injecting? Try disconecting the fuel line after the primary filter and see if fuel spurts out when the key is turned on. That will verify that the lift pump is moving fuel toward the engine. Then again after the secondary filter, to make sure that's ok. What about the air filter? Could it be clogged?

Since this a 2010, I would all Spartan. This is all under warranty and they will even work with mobile service. Make sure you use their emergency road service number because they always have a tech on call if it's after hours. Good luck.

Diesel engines have no ignition. You shut them down by shutting off the fuel. It sounds like your fuel shutoff solonloid valve is bad. This happened to us many times going to shows. I always tywrapped the valve open and cut the tywrap when we got there. You can do this to test the valve.

DO NOT LOOSEN ANY FUEL LINE FITTINGS! Unless you are experienced in High pressure common rail injection systems. Since approx 2003-2004 Cummins diesel has used high pressure common rail injection and the fuel in the line is under high pressure and can pierce your skin injecting diesel fuel into you that can possibly kill you.
