Check fuel pressure and compare to spec for your car. Check to see if you hear it come on when you turn key to ACC. It is a faint sound so you have to be quiet when turning the key. Get a helper if needed back by the tank to listen. Check the relay also. Many systems use a relay for the fuel pump.
If you switch the ignition to ON, The fuel pump will operate for about 2 seconds then switch off. Check the left front kick panel on the A pillar. There is an impact switch which switches the pump off. Press that button in. Also check the operation of the Fuel pump relay. Its located in the main junction box above the fuses
fuel pump is switching on and fuses and relay is ok but vehicle still don't start
Check for a faulty fuel system pressure regulator. If the pressure regulator is stuck open , it could be returning all the fuel back to the tank. Check also the fuel pressure at the fuel rail. The pressure is between 2.5 and 3.0 bars. Even if you have fuel in the system there might not be enough. Check also for a damaged or blocked fuel line from the fuel pump to the fuel rail. If the Start relay has a short circuit , the engine will crank but will have no spark at the plugs. Check also that the fuel tank has ventilation. Undo the fuel filler cap and check if there is a vacuum sucking noise when unlocking the cap and removing it.
did you get the gar right? if not check the sensor above the starter its a two pin plug sensor it`ll work
