Thanks for advise. car recently had a new fuse box fitted. had a good inspection, battery was flat so took it off too charge it and noticed a thin blackand grey wir had broken off at th negative side. Repaired this wire, once battery fully charged th car fired up. Fingers crossed that is the fault. Wire must of bn broken/fraid for a while and when hit a bump must o been enough for it too stop the circuit. car running fine now. so will keep it posted.
