I have a furukawa fd45p with Isuzu 4 Cyl, zexel injection pump. I'll start with what I've replaced and cleaned. Got the dozer and immediately started having power problems. Replaced fuel filter replaced in tank fuel screen. The tank had about 2 inches of rust and sludge in the bottom. In the summer did all this and it would act up at the beginning but would smooth out and run fine the rest of the day. It sat for about a month and started using it 2 days ago it will run fine for about 10 min and fall on its face. Starts missing and blowing grey smoke (raw fuel) it clears up some when idled all the way down but never really clears up. Let it sit for about 15 min and start it runs fine for 10 to 30 min and does it again. This time I drained tank and changed fuel filter twice new fuel screen and made sure fuel was clean. It still does or is just a gutless wonder. Can prime engine after it does and it fires right up wit run for about 10 to 30 min. It either dies directly or starts missing and blowing grey smoke. Please help.
