Typical of my car! Yes checked again today for spark as was hoping that new amp may have solved it but it hasn'tWe all had to start at the beginning...a digital multi meter is cheap and easy to use...advise on here if needed...
just for clarification have you actually checked for a spark at the plugs I know you say there's no supply at coil even after a supply from battery which is odd... things don't seem to add up..
