Stupid Airpump!!!
 

So I installed my Profec/Efini Y pipe this weekend as well as some other small shit.
Needless to say I had to remove the airpump to access everything easily.

Well I finished the install and start putting everything back together when I notice my harness to airpump connector is COMPLETELY shot.

Quick thinking, i decide to hardwire it in(since I probably do away with it soon anyway).

Get done hardwiring and start her up. Immediatley it sounds as though there is a rock tumbling around in the airpump.

I pull the AC fuse thinking this will kill the airpump. My idle gets erratic when I pull the fuse and the clanking sound remains.

Why would the pump still be spinning or making noise with the clutch disengaged? I guess it could be something in the pulley itself, but you think you'd be able to see it.

I'm at a loss and pretty pissed. I'm gonna get another pump I guess and do the hardwire BS all over again.

any ideas? .....besides ditching the pump(not yet)

thanks

The air pump can free-wheel the outer pulley, or the inner pulley kicks in when the magnetic clutch is engaged. Most likely something got stuck in the pulley or it ate part of a bearing internally.

Good thing is I've got a spare air pump :). Give me a holler tonight.

I might have to hit the junkyard sometime to see if I can find an airpump connector on another Mazda harness. That connector takes a lot of heat abuse and can be a pain.

The car will idle funky with the stock ECU and no air pump. Been there, done that. That's normal.

got another connector coming from Fritz.

Like to get that pump from you for sure.
