Morris,

When a non computer controlled Diesel won't run, its almost always a no fuel condition.

Loosen the banjo fitting on the top of the fuel filter and pump the primer pump. Fuel should come out. If it doesn't, either the primary filter or the tank screen is plugged. If you can blow thru the primary filter easily, its not plugged.

So next is to check the tank filter. Take off the rubber fuel line leading from the tank where its attached to the steel line. Fuel should run out rapidly. If not, the tank strainer is plugged. This is providing there is fuel in the tank.

No or dripping fuel means the strainer is plugged. If a little fuel is coming out of the fuel line, let it drip until the tank is empty or try to siphon the fuel out. Then unscrew the strainer ring and clean the strainer. If there is a brown silicone rubber like substance on the strainer, it is fungus and only a fungicide treatment will kill the fungus and clean out the fuel system.


If U have fuel at the secondary filter, it could be the secondary filter is plugged. Replace it and try starting engine. Pump the primary pump rapidly about 50 times after U replace tge secondary filter. Its easier if U put fuel in the new filter before U install it.
