How does it run when it is cold? Does it have fast idle? If the fuel pressure is good, you might have a cold temp sensor stuck in high resistance making the ECU think that the engine is still cold. The sensor is at the back of the engine behind the intake, check the resistance both cold and hot.

N.E.O.
