I still have this intermittant starting issue. It's a hestitation in starting or the engine starts to crank but stops immediately. But this happen only once in eight or nine starts otherwise its perfect. The engine does not continuously crank and not fire. I 've always got it started when this does happen after 2, 3, or 4 turns of the key. Hasn't left me stranded yet but very frustrating. When it does start it fires up immediately and runs fine. I "think" it accures more in hot weather and most of the time in late afternoon Thought it might be the cam postioning sensor and it still may be, but found that the two local dealers don't stock them for S70's and have never replaced one for an S70. Makes me feel this may not be the problem. Its not the RPM sensor, I replaced that. The battery is fine and the ground and connection are good per the mechanic. It may be this antenna ring connection issue, but its not a cranking and no fire issue. Its a 1/4 or 1 second crank and stop immediately thing. Ps, the starter, ignition switch, PNP and immobilizer have been replaced. Does anybody out there have any thoughts or have heard of this problem!!!
