Just purchased a 2004 sc430 two weeks ago. Twice this week the engine will turn over but not fire. When I left for work engine would not start. I waited about 10 minutes and it started right up. Today came home and went to leave about 15 minutes later and same thing happened. Waited about 20 minutes and started right up. I called the dealer and was told that if other keys on the ring are touching, this may interupt the signal. Anyone ever heard of this? Also when raods are wet I get loud squeaking from back seat area, sound like squeaky bed springs. Anyone have any ideas?
