Hi, 1997 A4 1.8 turbo petrol. No spark on front number one cylinder. I have tried another on plug coil/amplifier and new plugs but there is nothing. I have checked the connections under the coolant reservoir but still no spark. I do have a continuity between the crank sensor and the three contacts that connect to the plug coil top. The problem is not related to compression it is a spark supply problem.
Any ideas would be appreciated please.
