Engine Pull Start Knobs Won't Pull?

Apparently only when it has autostart enable then u have to put them on before, if its not on autostart, you can pull the starters and then a magenta line will appear on the N2 bar where you have to switch on the fuel switches

You can also pull the starter, then place the Fuel Control from "Cutoff" to "Run" That will then illuminate the starter. I know Virgin Atlantic pull the starter, then add the fuel in Auto Start. Below is from the SOP's of QFAutostart allows the EEC to control fuel and ignition and automatically abort thestart for certain malfunctions. Pushing the Autostart switch ON arms autostart.Pulling the Start switch out (held out by a solenoid) arms the start valve and opensthe engine bleed air valve. Moving the Fuel Control switch to RUN initiates theautostart sequence
