First of all thank you so much for your donation.I emailed you the long trouble tree for P0411 and a diagram of where and what the pump look's like. There are a lot of thing's that code set that code you will have to follow that trouble tree that I emailed you. As far as your air bag light those are tricky to diagnose I would need the trouble code your air bag computer has to start with.
