Thanks for that Steve, I shall leave the crank sensor alone and see if there is vacuum present when running (if I can get it started)at the EZL unit. Any quick test to check the temp sensor?
I can see there are different positions on the plugs to the EZL unit but I presume these are for adjusting timing for differences in altitude or gas grades. I have not touched these as the problem occured overnite, no previous mechanical or electrical work was carried out prior to this.
