Mooing sound from right under the SBc
I've got what I can only describe as a 'mooing' sound coming from the right side, under the SBC. I think it's the secondary air injection pump but I'm not 100% sure. Is there a way I can confirm that?

Don't know but I'll jack up the car tomorrow and take a peek. I'm guessing that if I unplug the connector I'll get some warning lights. But if I don't hear the sound, I'm in the right direction.

The air pump only runs at startup for a minute or so. Is that what you are hearing?
I believe there is a fuse for it. Pulling it is probably easier.
The only cow sound I can think of is the fuel pump and it may reverberate through the chassis.

Yep. About 30 seconds and then again about 5 minutes later. After that I won’t hear it again until it sits overnight.
I’ll take a look to see if I can find the fuse.

Here's what I did on DAS. I haven't driven it in a few days so I got a battery warning. I didn't want to do it without turning the car off so I did it with the car on. But I'll have to wait till tomorrow to see if this worked.
