there is weird noise, like almost sounds likea vacum sound,coming from behind the passenger headlight. i had never heard it this distincly before. but i guessed it kicked in over night and ran my battery completely dead, not even a click when i tryed to start it this morning. i hooked up a charger to the battery and immeditaly this pump or something kicked back on. and the car turned over but not start. i left it awhile to charge and finally it would start but cut back out within 2 seconds. what the hell is going on here?

 

Possibly the secondairy air pump.
