Posting on behalf of someone else, basically for some reason when they turn the ignition on the car gives 1 spark?! then when u crank it you get no spark what so ever. It was running fine till the middle of the week. Its had all new sensors bar the crank sensor, tried a different loom in it but still no joy. He did try a 3door ecu but didnt realise they were different to sapphire ones so obviously that didnt work, althou should an L1 ecu still work in a saph if it had the L1 chip in it still?! I know he tried the L1 chip in te L6 ecu which obviusly wouldnt work but he didnt know that at the time. ignition module is fine btw too.

He's gona try another crank sensor and see what happens but failing that any other ideas?!
