Take the pump to a desiel laboraty and get it serviced and also the nozzles. next get the self (starter) checked and service if required. next check the desiel in the tank. next check the battries fully charged and clear the fuel airlocking and start the beast.
remember while unbolting the self you will find a spacer. if its there than remember to put it while bolting it back.
