Hello I’m new here and have a 60inch toro zero turn with a D905 kubota Diesel engine in it, so when I bought it off someone they said it runs for 30mins and shuts off it has 2 tanks on it and I replaced the fuel filter it has 2 inline filters, it ran cut but after about 2 hours of running it would slowly idle down and shut off, so I noctied the tank and stuff at the bottom so I empty both tanks and cleaned them very good and I look off all the lines to and from the tank and cleaned them and put new fuel filters on again and put brand new fuel in, I bled the air from all the lines and still can’t get it start, it will run off Diesel If you squirt it down the intake, I did remove the injection pump to make sure the fuel shut off was working and it’s working and every moves but still can’t get it to start or run. Does anyone know what else it could be??
