Nissan Frontier Motor ZD30

Hello everyone, I have problems with the injection pump does not supply fuel to the lines of the injection, pressurize with the priming pump and nothing. I hope to have solutions to this problem, thanks.

Diaphragm of the pricked primer, fuel filter with broken stamps, supply hose from the broken/punctured tank, or maybe the nozzle that is inside the fuel tank has been released and does not suck fuel, greetings.

I spend a case in the workshop .. similar to your problem .. which the pump does not supply fuel. Disconnect the handles that come from the fuel tamque and in a gallon with diesel connects the tasks direct to the pump ... and turn it on if still putting it directly does not reach the injectors. There is no pressure. Possibly you have problems in your pump ... since these cars have in its pump an electronic module with an advance .. that over time or by the dirty fuel they damage it .. if that were the case ... you will have to replace the pump ... (eye the scanner sometimes does not detect pump flames)

You have to top the fuses that are well, then check the injection system from the fuel tank that does not have a broken hose or the hoses exchanged if everything is fine put a diesel gallon connected wing to the pump diesel input hose and if you do not throw diesel the problem you have in the pump which can be the PSG that is the computer of the pump or head da; ado. You can repair the injection pump in a Bosch Diesel Center Diesel laboratory or buy it new .....

Thank you very much Delis29, if today I have started to find garbage again in the entrance line to the pump (Banjo screw), it seems that when they replace the filter they take out the complete base and plug the hose, I will do this test with the galon and discard if I will have to look for a new pump.
