Ok, here it is:

Starting problem occurs as follows:

A) Only after sitting for several hours
B) The starter will turn and engine will crank over and over and sometimes will fire, but immediately shut down, and sometimes will not fire at all, but just keep turning.
C) The DAS light blinks when I insert and turn the key
D) After 3 attempts the car will start and run fine and start fine for the whole day.
E) The problem will repeat itself after sitting for a while.

So far I've changed the Crankshaft position sensor.
Is this the same thing as the camshaft position sensor ? excuse my ignorance

So what do you guys think?
