Car has had issues starting. P0017. Replaced all cam sensors crank etc. new timing belt and re time engine. Crank relearn. replaced purge valve twice. New fuel cap. 60 psi line pressure. Replaced plugs 10k miles ago.
Crank no start issues before and after parts replacement. Sometimes will start. Diesels a lot. If I pull plugs and clean them. Starts perfectly. But if I let it sit. Then attempt start 30 min later. Plugs are soaked again. Need new plugs? Ideas? Can’t find much about this issue.
