Try these things:

  • Disconnect vacuum hose at fuel pressure regulator and check for fuel coming out of the vacuum fitting on the regulator. If fuel is present, replace the regulator.
  • Unplug the mass airflow sensor and leave unplugged for the next several attempts at starting the engine. If the engine starts easily and runs well then the mass airflow sensor is faulty and will need to be replaced.
