This car has been driving well; very powerful.

This car has been driving well; very powerful, and one kick I go. It is a Nissan caravan with ZD30 engine. I parked it on sloppy ground with low fuel, near empty but light had not started showing. After 30 minutes I set up to go but the car did not start. I tried several things including diagnosis and mechanical checks on the pump but nothing has worked. It's more than a month now and the car is still grounded. It's ex-japan
