Hi guys,

Hopefully there are some MS gurus on here

I have a problem with my zetec turbo build. I am using MS2 with an EDIS 4 and I am getting no spark. I have followed the diagram below



I have tried the following things to see if I can resolve it.

Tested 12v supply
Earth is good
Reversed the crank sensor wiring to check polarity is correct.
Changed EDIS for a known good module
Gave module 12v perm live from battery incase I was loosing power on crank.

The only thing extra to the diagram above is a tach signal to my OEM ECU for the dash clocks.

Am I correct in thinking the EDIS will spark regardless if the MS is connected so the problem must be with my wiring?

Please help as I'm at the end of my tether trying to get it going!
