There should be a little notch on each cam gear that lines up with a notch on each side of the cam cover.
Try looking at it from the side and rotating the engine with a large ratchet on the crank bolt (turn clockwise only).
The timing marks will line up every TWO rotations. You'll see how the notch on intake and exhaust cam gears both line up with the notches on the plastic cover.

If the air pump system is setting a fault, then the check valve is probably bad. If it is not addressed, eventually exhaust gases can run back through the air hose to the air filter housing and destroy the MAF sensor, causing these types of problems.
The fuel pump also fails and is a more likely cause of the stalling, and it wont set a code.

Hi:
The SRS light is the air bag system, or supplemental restraint system. It is possible that it could just be on If you have had maintenance done on your car recently, but your airbag system is inoperative till you get the system reset.
