RE: Goes away in 15 seconds -

from the RAVE:
The ECM checks the engine coolant temperature when the engine is started in addition to the elapsed time since the engine was last started. The engine coolant temperature must be below 55
°C (131°F) for the SAI pump to run.
NOTE: The ambient air temperature must also be above 8
°C (46°F) for the SAI pump to run.
Also, depending on the long term 'modelled' ambient temperature determined by the ECM, the minimum elapsed time required since the last engine start can be up to 8.25 hours. The period of time that the SAI pump runs for depends on the starting temperature of the engine and varies from approximately 96 seconds at 8
°C (46°F) to 30 seconds at 55°C (131°F).
So I was thinking maybe the SAI would run a little longer than 15 seconds. Just put your hand on the plastic pump, should feel it shut off.
