I have a Astra H 1.7 CDTI mk5 I have oil leaking out of the top injector seals so I unbolted them and disconnected all the fuel rail on top and the electrics for the injectors. I then sealed the two seals on the top and put it all back together, I then tried to start the car and it try's to turn over but it won't fire, before I done this job the car was running perfectly fine!!!
Any suggestions ??

Sounds like you may have (a lot of) air to bleed out of the fuel system.
