Thank you for your reply Duncan.
I measured the current yesterday and there's 0v going to the pump. So probably, like you said, ECU, relay or wiring. Do you have any clue which one of the relays belong to the pump? Is it common for the ECU to fail?
I really dislike these kind of problems.. Especially since I have no way of getting the car to my garage.
I don't think there's a immobilizer.
I have a pressure gauge in the enginebay.
I start every sentence with "I" :-)
Cheers
