Need urgent help - cleaned injectors now wont start

Hi so ill get right to the point, I cleaned the injectors in my 2005 megane 1.9 dci and when I put it all back together it wont start? Ive tried to bleed it with primer ball but nothing at all is happening as if its leaking air but i cant find the source. Also do I need to replace the copper washers on the injectors? I head i can heat em up and reuse? Please help my car has been in an underground car park for 3 weeks, Ive already gotten 2 tickets and a flat battery so its sitting down there with 2 unlocked doors



Thanks in advance
