I would start by checking the fuel pressure, a bad pressure regulator could easily cause this. I don't have this exact vehicles specs but the regulator will normally be on the fuel rail that feeds the injection system. On many there will be a vacuum line to it, if you remove that line and smell or see gas in the line the regulator has failed.

It's also possible that you have a sticking injector. The pressure test can show that as well. If you turn on the pump and the pressure jumps up, you then block the fuel lines back to the tank, if the pressure holds you're OK if the pressure drops you have a leaking injector or more.
