Hey guys I have a similar issue, have checked the ballast and ignition switch and they seem fine...
Im getting the car ready for road worthy and it was starting fine a few weeks ago.
Had to tidy up wires under dash with zip ties but don't think it could have been that.
Have attached a video of it.

Thought it could just be starter solenoid but its odd that it has happened all of a sudden.

Cheers,
Ben
