I had one like that.
Turned out it was the plug on the alternator. It seems the ecu wants a signal back from the alternator that the engine is turning before it will let it start. Or something. |

How long after turning it off do you still have voltage? The system stays alive for a short time after switching off the ignition. Of course... 7.2V is a strange amount to have anywhere in the subaru loom... where are you measuring it? |
