Ole, you said sputtered and stalled. How many times did you prime and try to crank? The reason I ask, is after running the fuel pump and fuel lines after the filter completely dry, it may take 3 or 4 prime and crank events before you get them to completely refill.

The fact that it will sputter almost eliminates all electrical issues.

If I were in your situation, this is what I would try. I would disconnect the the fuel line from the tank into the fuel filter. I would adapt that fitting into the fuel filter to allow me to attach a three foot section of clear hose of at least 1/2 inch inner diameter. I would run the clear hose into a fresh 5 gallon jug of diesel. Then I would prime the heck out of it.

My logic is the use of the can right at the filter will eliminate any possibility of the fuel line sucking air. The clear tube will allow you to sort of see if the fuel is flowing. If it cranks, let it run until it smooths out and stop. You do not want to suck all the fuel out of the can and lose prime again. It will use up the five gallons much faster than you think because the fuel pump oversupplies the injectors and the fuel not used goes into the fuel tank.

Another trick to prime the engine is the use a NEW pump up garden sprayer, and cobble a fitting into the fuel input of the filter.

The sputter and stall just sounds like a fuel issue to me. The Serious 60 is known for difficulty to prime because the fuel pump is gear pump, which doesn’t “suck” as well as some other designs.
