And as pizzaguy sayed it could have many causes.
A SIMPLE fuel pressure test would tell him the condition of the fuel system. That is, in my mind, the most easy and fundamental test one can do on today's fuel injected engines.
EVERYONE should keep in mind: The ECU has NO CLUE what the fuel pressure is, there is NO SENSOR to tell it what the pressure is, so the ECU assumes 58psi. If the pressure is off, there will be a struggle to get the fuel/air mixture correct. Why the HELL there is no fuel pressure monitoring on today's cars is beyond me.
