does it turn over when you try to start it?

I had the same problem with mine a wee while ago (1.6 CVH EFi Turbo), turned out to be the power cable to the starter motor was too close to the block and the plastic casing had melted away, so the bare wire was shorting-out so the starter wouldnt even turn over.

If I left it for while it would start no probs, or if I got a jump start.

If it turns over, then I'd imagine the starter is maybe not the problem? Always something to check though
