engine start failure
Sometime I can't start my engine and sometime I can.I can tell by the sound that the starter is working, but the engine won't start.I went to 3 services, and they told me there is some problem with injection pressure, but they don't know what it is. Car's computer doesn't show any errors. Their only idea is the high pressure pump, but they don't know why it sometimes starts. Did anyone have similar problem? Can you at least tell me if the problem is electronical or mehanical? Thank you.
