My 96 accord lx (165000 miles) 2.2l 4cyl. turns over but won't fire up followed by a hissing sound around front of engine block when stop cranking the engine,like compresed air from cyclinder at thehead gasket?No loss of coolant and oil looks fine.We live in Michigan and havehad super cold temperatures last few days, Iwas starting the vehical and letting it warm up every day, but ithadn't been driven in a few days. It hadn't overheated either.I am hopingit's just the head gasketAny ideas? thanks from Frigid Grand Haven Michigan!!!
