whack the starter with a big hammer ( don't crack it though, careful ) - might not be engaging in the ring gear on the flywheel. Could be just a zany coincidence and nothing at all to do with having taken coil pack off......If the fault was ignition related, the engine would still turn over. With the strongest spark in the world, she won't start if she won't turn over ( I used to know a girl like that 😃 )
