im on with my car at mo trying to sort the fucker out.its been acting up as it fires first time,but as soon as it warms up if you turn it off it wont start back up for ages.

its been left out on the drive for a few weeks now as i couldnt be arsed with it,so idecided to fire it up today and its just turning so i took the lead off on cylinder no1 and there's no spark.but when you turn the ignition on there is one spark and that is it.it has recently had a brand new phase sensor(im not sure if it is gapped perfectly).i have changed the crank sensor, it wasn't brand new but it was in better condition than the old one.any ideas or help appreciated as im getting pissed off cheers
