I had the same problem with mine mate. The earth cable was a bit of a piss fit so the car just died on me and wouldn't start. All sorted now though.
Hope it's that simple for you.
Anyone got any picture of what the fitment is like on the top of the boot?
God, I must sound like some sort of pervert with a weird fetish for spoilers....!
Cheers dude.
I've got the CUP spoiler on mine but can't decide if I like it anymore. Toying with the idea of swapping it for a sprint or removing it all together...
Anyone got any decent pictures of the sprint spoiler fitted? I've searched and can only find a few.
Would be ideal if people could post pictures of theirs from various angles. Cheers :)
