986 Boxster won't turn over

That sounds like the job. I shan't get chance until tomorrow now to try but I didn't attach any ground wire just the 5 multiway plugs. Fingers crossed this is the one!

Thanks for your help however. I'll be very pleased if it solves my issue.

thanks corn, appreciate it. Mine is slightly different. It's a black cartronic Bosch unit.

Also by checker. I have a very basic obdII checker. Would this suffice or is it not quite in depth enough.

Thanks again
