My car has had a couple of no start instances while over at the Cruising the Coast venue. All have been after several hours of driving. The battery is new and holding charge. The 418 starter has been rebuilt. All connections seem to be tight. The symptom has been while turning the key - nothing happens. No sound at all from the starter. Power to everything else. The lights will dim when turning the key to start when the engine will not turn over. Then minutes later, it will be a perfect start. No drag at all. It's like a hit and miss situation. It's happened a couple of times. Where to begin?
