2006 mpv where is the fuel pump switch at - 2006 Mazda MPV

Check for spark. Also injectors could be clogged. Not enough information to tell really.

There are a lot of things that can cause this, (e.g. crank sensor, coil, cam sensor, ECU, other sensors on some engines...)
Check if there is a spark. Check if fuel is being pumped (check fuel pressure at engine if possible).
Why was the fuel pump replaced?
Is the fuel pump powered up? Check for power at pump. Be aware that the fuel gauge wire will have some voltage on it so don't mistake it for pump power. If no power, there is a fuel pump relay somewhere (e.g. sometimes under the passenger seat) that cuts power to the pump if the engine is not turning. These occasionally fail (they have a bit of electronic circuitry in them).
Is there any fault code set?
Good luck

Have you ever run out of fuel in the last few months, or run very low on fuel. If so replace the fuel filter.

Only on a ford

Do you not hear the fuel pump come on?

Do you have spark or injector pulse when cranking?

there is a fuel cut off, you will need to reset it:

The fuel pump relay is located under the carpet on the passenger side (front). Remove the kick panel and the door runner lift carpet. It is to the right of the PCM (computer). Good Luck Tim

The fuel filter for your vehicle is located on the Fuel Pump Unit, which is located in the vehicle fuel tank. The Fuel Pump Unit must be removed from the top of the fuel tank in order to replace the Fuel Filter.

the fuel pump is in the gas tank change the fuel filter at the same time

Drop the fuel tank,it is in the tank

It is typically located in the rear of the vehicle in one of the side compartments. It has a red button on it. I would also check the fuel pump fuse, and relay.
