Car starts perfectly when cold or hot, but in between it requires two to three tries. The engine then sputters to life, sounding like it is not getting enough fuel.
Once it gets going it runs fine. No engine lights. I already replaced the air filter and the fuel pressure sensor.

You were right! Low fuel pressure caused by a bad fuel pump. Got a Delphi and the car starts perfectly - at all times. Many thanks!
