Chevy Blazer hard starting, white smoke
White smoke is an indication of engine coolant being burned. This can be from a failed lower intake manifold gasket or head gasket. Check your radiator to see how low the level is…
This can cause the spark plugs to foul out, the o2 sensor to go bad or have strange readings and make the engine hard to start and run poorly.
Start by having the cooling system pressure tested while the spark plugs are removed. You may see coolant come out of spark plug hole as proof the head/manifold gasket has failed.
