ABS noise up under my hood

[Computermangamer]

I have a 1994 GMC Sonoma and the abs is making a noise up under my hood. i looked on another forum and they have said that the abs pump relay could be bad. Is my abs pump relay bad? And if it is, where is it located at under my hood of my 1994 GMC Sonoma truck. Help would be very much appreciated.

I had someone else check the abs pump relay and they said it is working. if it is not the abs pump relay, then what else can cause the abs to be making a noise up under my hood? help would be very much appreciated. thanks!

Pretty much what everyone else said: foamy engine brite the whole thing, wait a bit, then hose er down. It works really, really well.
