how did you "test" for spark?

read up on how to test for spark if you dont know,after that you need to check if you have spark to all four coil packs if you havnt got spark to all four its probably the cps wiring or the sensor itself(i was lucky just a loose wire iv not so long ago had the same fault) if you have spark to 3 of the packs but not the 4th try swapping the packs round that way you know if its the pack itself or the wiring leading to it.if one of your packs are faulty you need to get another one =) simples
