Hello, It sounds like you may still have a leak between the cylinder head gasket and the cylinder head allowing coolant to leak into the oil passages and cylinders. A blown head gasket may cause a number of different symptoms. A head gasket that fails between cylinders will generally cause a misfire and potentially compression leaks from one cylinder into another. Low compression will eventually result in a rough idling engine and eventually cause the motor not to start as you have described. I would recommend having an expert from YourMechanic come to your location to properly diagnose the symptoms you describe.
