You need to find the source of the air in the lines. Until you get rid of the air the engine will never start.

LK is right. You need to purge the air. I had two of those fantastic wee cars. The thing works on the CDi2 technology if I recall and you should be able to get it running for a few seconds on easy start. Do that two or three times with 30 seconds between cranking and that should get it running for a few seconds each time, so keep the key fully turned against the stop for about 20 seconds or until it dies again and that will start to bleed the fuel system. After a few cranks, it should fire and run properly. Hold the key on again for about 30 seconds to complete the bleed. It worked on my 2005 A Class and my 2002 C Class.

The important thing is to get it running well, then once you've done that replace the O rings on all the plastic pipes one by one. After replacing one ring, restart it. Once you know how to start it again it should be quite easy and it's easier to start it again after it has warmed up a bit.

Finally, have a google for Lofty's A Class Page. He has practically dismantled his A Class and he also has comprehensive written guides for fixing just about anything that went wrong with them. There's hundreds of photos as well.
