Has the service schedule been followed?
Plugs, air filter, and fuel filter?
You may have a plugged fuel filter or possibly a failed air mass
sensor. If you have access to a fuel pressure gauge, connect it
to the test port on the front of the fuel rail. You should have 3.8bar pressure whilst cranking. If pressure is low, look at filter
(which also contains the regualtor) or pump. If no pressure,
look at power supply like the relay or fuse for the pump.
Good luck.
