I am having a cold start problem (car left for a long time), if I leave my car overnite or for a long period of time I am having a problem with the start.
The first attempt to start the car bogs and does not rev to idle immediately.
The second start goes fine and the idle is super smooth and the car runs superb without hesitation.
I am thinking that there is a loss of pressure on the fuel rail itself. I am not having any issues at all with acceleration or rough idle but I definitely am suspecting the loss of pressure from the FUEL PRESSURE REGULATOR, or perhaps a check valve somewhere near to the fuel pump.
Anyone have any suggestions or have experienced a similar problem please reply.
I am having trouble getting the gas pedal trick to falsh the CHECK engine light. I am depressing the pedal with the KEY at position 2 and it doesnt illuminate the CHECK engine light to read fault codes, does that mean that none are stored?
Actually that doesn't sound like a problem at all to me. If on the first attemp a fuel injected vehicle doesn't start and the sensors read that it's cold, the next time you turn the key the ECU richens the fuel mixture so it starts.
P.S. Wups I thought you meant cold temperature. If it's been sitting overnight and having trouble check your spark plugs to see if they have oil on them and have fouled. An easier way than taking the plugs off would be to just take it for like an hour trip somewhere, but only if it's only been driven in town for awhile. Then let it sit and see how it starts.
Could be a bad fuel pump, or a leak in the fuel line. Check for any drips.

Thanks for the reply. The only problem is when the car has been sitting for more than 6 to 7 hours it is hard to start on the first crank is all. I live in the Bahamas, so temps here never fall below 60F. The fuel pump is not suspect because I am not getting any sputtering or hesitation at all, actually the car is very spirited for a twelve year old. I'm quite pleased with the performance.
I still cant get the fault codes to read, will consult the Bentley AGAIN.
