Have you checked that the right pack is off? Start lever on?

Since you are getting a rise in N2% sounds like something with the packs are not set right.

Typically the cause of low N1 during start is a pack being on. Maybe if you posted a screen shot we'd get a better idea of what's going on.

Are you trying to start with the the APU or engine 1. If engine 1 you probably don't have enough bleed air, bring N1 up to about 40%. Make sure the packs are off.Tom beat me to it! :-)

Have you forgot to raise your "Engine start Levers" or not?....../ Leffe

that's the overhead panel and this is the efis paneli don't know if you can see but N2 percentage is on 18.1 and N1 is on 31%see what's wrong please

[Leffe 4]

Your packs have to be off. Also as said above, did you raise your start lever, when reaching 117-18%/ Leffe

the engine start levers have to be rised on 25% of N2,so i should not do it up to that moment..but a've tryed aniway and it doesn't works

The packs aren't off as far as I can tell, you've left them on auto, move them to the OFF position.
