You can check the glow plugs with a multi meter, first ensure that each plug is getting powered up on the glow cycle, test this with a volt meter, if this is ok, disconnect each plug from the power source and test continuity between the thread wher the power wire attaches to the glow plug body, if it is an open circuit, the plug is faulty, if one or more plugs are faulty, fit a full set.
