Today I scanned my car and found that the Air Pump fuse had blown, I found a 40amp where there should have been a 20, I replaced it with a 20amp and it blew, tried another one, it blew, then tried a 30amp it also blew. What could be causing this? 95 z28. Thanks.

 

a short in the system or an overload on the pump which means its time to replace it(possibly a loose wire)

 

Your air pump is most likely shot. They trap moisture and eventually corrode from the inside.

Carefully unplug the connector at the air pump and see if it still blows the fuse. If is does, you have a short somewhere in the wiring to the air pump. If it doesn't, the air pump itself is most likely shot. Remove it, disassemble, and you'll see.

Mine finally died last year, on my '94 with 170k miles.

 

Those are never easy to find. Good Luck but yeah you have a short somewhere.

 

Have you done the air pump recall? If not, now is the time to do it.

 

I ran into the same problem. I did what was suggested above and removed the pump and took it apart and voila, moisture built up and killed the pump. Just for giggles, check your MAF screen for any debris that might have come out of the pump. Mine was coated with some spongelike stuff that was on the inside of the pump.

 

was this recall only on the 94 and 95 's or also 96 97
