I have a 1200 diesel Hijet which lacks power. It only pulls at a certain rev range when the throttle is only slightly depressed.
Pushing the throttle to the floor makes no difference.
ItÃ¢â‚¬â„¢s a 1997 with less than 20K on the clock so hopefully the engine is sound. The engine starts first time with no problems and does not smoke.
I have checked the air filter and thatÃ¢â‚¬â„¢s OK.
Can anybody suggest what could be the problem, is it the pump, fuel filter, or something as simple as air or water in the fuel line.
Any help would be greatly appreciated.
