you havn't done what i did put a wire that should be a live on an earth, the one i did were around the starter motor. earths are yellow and green just like houses. and there were a black wire with a 'O' connector on it that should have gone to live.

was pulling my hair out for about a fortnight untill i realised this while flicking through the wiring diagram

Did you put the plug back on the fuel rail attached to the inlet manifold? Or even the one on the top of the coil pack...

yes it could be. mine turned over. no spark, fuel pump wasn't priming. the imobliser light were flashing on the dash. but it turned over like normal.

swapped this wire to the live on the starter first flick of the key and she started. :panic:

could have cried
