Mirage2000 won't start

Hello,

I'm requesting your help : my Mirage won't start.

I watched every tutorial possible, i read all the threads talking about mirages not starting.

But yet, it still doesn't work for me.

This is what i'm doing when starting up my mirage :

- Battery on

- Auxiliary ground power unit

- close the canopy and lock it

- parking break

(My INS is set as already aligned)

- throttle at 0%, i click the red button to make sure it is

- left and right pumps on

- starting pump on

- fuel cut off closed

- lighters on G or D

and I try to start it, yet nothing happens

What am I doing wrong ?

(And there's 2530kg of fuel)

Thanks for your attention

Fixed the issue, it's left click on the startup button even tho it doesn't show any mouse animation; and not right click
