Answer
Steve,
Ever if there are no warning lights on I would have the codes read to see if there is one that is pending. If there is no power to the injectors sounds like a control unit or throttle housing module fault. Check to see if there is an updated electronic throttle housing download at the dealer. Otherwise I have not heard of a problem like yours.
