Here's a link to where your fuel filter is... How do you change the Fuel Filter on 2000 Nissan Quest and

Probably a dirty fuel filter restricting the delivery of fuel to the engine.

Sounds like you have a issue with fuel flow . Try to replace inline fuel filter . Also Fuel injectors could need flushing or possibly replacing . Try filter first .

your problem is the fuel pressure regulator on the fuel rail. sending a picture.

Fuel filter is located under the rear of the passenger side. Under the car sill towards the rear tire you will see the petrol tank. The fuel filter is fastened to the side in line with fuel pipe coming from the tank. Easy to replace, but make sure fit the right way round using the flow arrows.
