My engine was running fine for about 10 minutes, then suddenly stalled and won't restart. It cranks, but no fire. I thought it was is an air pocket in the fuel line. I disconnected the fuel line, which comes from the engine mounted fuel filter, at what I think to be the injector pump.With the key on, I get plenty of fuel out of this fuel filter. Not sure how to check to see if the fuel is making it to the injectors. The metal fuel lines going to the injectors have a large nut on the outside. It appears to be very tight so before I force it, I thought I'd check with anyone who has more experience with these engines. I bought the boat last fall, but it has been a while since I worked on a sailboat diesel, and it was not an M25. Any help would be appreciated.

Have you checked your Racor filter to make sure you don't have water in the fuel?

Racore looks good, I was about to replace it and the engine filter also before this happen. I just removed, cleaned, and refilled the fuel tank with fresh diesel. My guess is that this process may have introduced an air pocket.I was looking for info on how to bleed at the injectors. Not sure which nut to loosen.

You shouldn't have to undo any nuts or bolts. :)
