Yesterday my daughters 80 300d 123 wouldn't start. The lighit were all bright and it wouldn't jump. I tapped the starter and solinoid and it started up instantly. Today no start again so I pulled one off of a parts car I have that has been sitting up for 2 yrs. For a split second it turned then stoped. I tapped that one and nothing. Could there be something I'm missing or is it possible the old starter was to old. Any Ideas before I have to get a new starter. Thanks Ray The glow plug relay fuse is good
