Check mo yung connection between fuel filter my strainer na nakakabit dun sa fuel line.. usually nagkakaroon ng parang putik dun.. medyo maliit lang yun. pag hindi nalinis yan kumakadyot kadyot yan and walng power kahit diinan mo yung gas pedal.. sa diesel kasi kailang ng malakas na pressure.. kalimitin akala nila injection pump ang sira.. pag ok naman at malini.. check your injection pump..
