Hello,

Sounds to me like an immobilizer problem. On the S70, if the immobilizer receives no signal from the key or ECM, it will allow the engine to crank but not start (as opposed to some models that won't allow the starter to run). It also may start for a split second and then die, just as you described. Has this happened with different keys, or always the same key? I'd hate to see you go to the dealer if you don't have to, but I would be curious to see if the ECM or immobilizer control modules have any DTC's stored (an immobilizer fault code in the ECM will not light the check engine light, even though the code exists). Immobilizer faults are not uncommon and will cause all of your symptoms. Let me know if you have any further info.
