how can i start my citroen picasso?

Don't worry... it's not as bad as you think!!!
It would be a lot worse if it was petrol into a diesel. A garage will get it started again maybe just needs the pump and filter drained. May be smokey for a short time till all the diesel has been dispersed? Good luck.

Oh Sh**t. There is a whole lot more than just draining the diesel out and filling it with petrol take it to a garage or you will knacker your engine. You have been warned!!!
