Before changing it, they clean that valve since it gets dirty with fuel water after cleaning it lubricate it and before starting, change the diesel filter, although it seems weird to throw automatic transmission oil to the filter if it starts will see a radical change in the power they warn me
Change fuel filter by disassembling if it has water, when you take the regulatory value to blow in the pump and in the valve and put some oil to the filter to clean and try to unlock any incrustation, check mass cable that goes to the body and to the chassis eliminate errors in switch Fiat and the Suzuki.-
