How do you check Nissan 2.7 TD diesel pump timing?

To check the timing of a Nissan 2.7 TD diesel pump, first ensure the engine is at top dead center (TDC) on the compression stroke for cylinder one. Locate the timing marks on the pump and the engine; align them according to the manufacturer's specifications. Use a dial gauge or a timing light to confirm the timing settings are within the specified range. If adjustments are needed, loosen the pump mounting bolts and rotate the pump slightly until the correct timing is achieved, then retighten the bolts.
