    When engine is cold, starting is never a problem

    When engine is hot, stopped then re-started right away, there is no problem.

    Its only when left for more than a couple of minutes, it sometimes take alot of cranking to start the engine, after starting black smoke starts spewing out and idle is high about 2K rpms. It sometimes takes between 15 secs to 5 minutes for the idle to settle to normal and drivability before those times can be described as surging.

    I wonder is it caused by my fuel line. I've checked the fuel pressure gauge (located between the fuel rail and return line) after stopping the engine and fuel pressure drops pretty fast to zero. I've pinched the fuel line between the fuel filter and fuel rail, pressure stays about the same, but when I let go, pressure drops instantly.

    The fuel filter/regulator/injectors/pump has just been changed recently.

    I've tried to spot for leaks but couldn't find any wet fuel patch or smell any gasoline whatsoever. I've yet to inspect the car under a hydro-lift.

    Anyone has any ideas?
