Having trouble starting car in the mornings. I've replaced the battery and fitted brand new genuine Honda glow plugs. Had this issue for a while. Always starts well if I put the ignition on twice and wait for light to go out twice. If I try to turn over after light has gone out once it take quite a few cranks and belches out white smoke from the exhaust. If car has been running or sat in the sun it starts first time fine. Was hoping the new glow plugs fitted last week would have cured this. Any suggestions? In garage end of the month for MOT and service and was going to ask them to look at it.
