Hi everyone, so ive been trying to work out where ive gone wrong. i changed the clutch on my polo gti since it was toast and ive double checked the ground wires are attached to the starter motor. one to the solenoid and the other to the gearbox mounting bolt. double checked that i havent missed any plugs i disconnected and when i try to start the car i get lights and can hear the usual relay noises from engine bay but no cranking or anything.

ive checked the plug to solenoid is getting signal with test lamp and ive checked the starter motor runs.

Any help will be much appreciated because my parents want it off the hoist asap
