Expert:  Jerry Newton replied 3 years ago.
I wouldn't change anything yet. First thing is to know whether the air pump runs or not on cold start. Can you hear it running when you start it up?
Customer: replied 3 years ago.
no but a 30amp mini fuse blows after awhile and the check engine light come on
Expert:  Jerry Newton replied 3 years ago.
It sounds like a failed air pump. Which fuse is it, how is it labeled?
Customer: replied 3 years ago.
I'm going from mem but if I have to I'll go out to the car but I think it says a.i.r something... location is psngr sd. firewall lower fusebox right side as facing it 30amp mini fuse, just under some relay
Expert:  Jerry Newton replied 3 years ago.
Schematic


Looks like the AIR PMP RLY fuse is opening. It only goes to the AIR pump, so it's a safe bet that you need to replace yours.

The AIR pump is under the car, in front of the LF wheel. Here is a picture.

Customer: replied 3 years ago.

one last thing, can a beginner replace this or or should I leave it to guys of your level?

 

Expert:  Jerry Newton replied 3 years ago.
No, I'd say that this is something that a guy with average mechanical ability can figure out. 3 or 4 fasteners, a couple of hoses that just pull off, and an electrical connector, and you're there.

The pump is expensive though, expect to spend a couple hundred dollars on that.

Thanks Jerry! You're tha bomb!
