Test vacuum pump??
I'm out in the garage right now trying to figure out a problem with my cruise control system. Just like the other thread on here my cruise light comes on, I hear the relay click, but when I try to engage nothing happens. (Gotta love having a computer/TV in the garage. SVX + SuperBowl = Win)
I've got the vacuum pump pulled out but don't really know how to test it. I've done the impedance test that is laid out in the service manual and I think everything is in order. I want to find a way to make the pump activate while the car is in the garage to make sure that the pump is working properly. Any help soon is greatly appreciated! Thanks, Matthew EDIT: So I was looking closer, and I think I may have had the pinout wrong. This is what the service manual says for checking impedance. Quote:
Pins:--------------------------Ohms 2 & 3---------------------------7 1 & 4---------------------------105 (This isn't listed, but does show the correct impedance for pins 2 & 3. This has/had me confused) 1 & 2---------------------------52.9 2 & 4---------------------------52.9 I thought maybe something was backwards, but I just compared the pinout to the wiring diagram in my service manual and the colors coordinate correctly.

HAH
Yup, it's behind the battery and the fuse block sits on top of it. It's only job AFAIK is to run the cruise control solenoid

Re: Test vacuum pump??
Really? Weird... Must not have been able to get enough vacuum off the engine or something. I wonder how much they run, the vacuum pump for my Dodge diesel is like $380 I'm tempted to get the compressor for it (Mounts in the same location) and use it to run onboard air, and get an electric vacuum pump from Summit for the brake booster...
