Is your air pump working in the morning?? Check fuses if not.

1 Check the vacuum hose on the air pump valve. Its common for this hose to crack on the bottom right at the valve inlet.

2 If its not cracked, when your vehicle is cold check to see if the hose has vacuum. When the vehicle is hot, there will be no vacuum.

3 If all is good so far, check to see if the valve is opening with vacuum.

4 Is your air pump producing air at the outlet?


Good luck.
