Have 2001 Itasca Horizon diesel pusher, with CAT 330 (3126B). Changed filters, fuel and water/fuel filter and now it will not crank. Any help is appreciated.
I had same thing happen because did not fill filter w fuel. I took a air pump and placed a rag around the fuel cap and put the air hose in the tank. The air pushed the fuel to fill the filter up and cranked the engine. It started after 2 tries.
