Dear CStanley,
I changed the cylinder head and prechamber with new gasket and new set. and ı increased the HT water pressure abot 4.5 bar when engine stopped, and I remove the spark plug and peak pressure sensor. after ı pushed the start solenoid, and there was not any water leakage. I think there was a problem about ignition timing or after ignition module cable to ignition coil, there was a short circuit maybe. ı checked it tonight. what do you think?
