So at one time or another the boost gauge in my IX did in fact work. It now stays as dead as a doorknob and is useless. Everything is hooked up correctly, it's getting electrical power considering it will illuminate, it is hooked up correctly to the right lines and I even switched to another one to test it out and still reads nothing. With all that being said, it has to just be a fault gauge correct? Or am I missing something completely? The gauges are GlowShift if that helps at all. Considering getting new ones anyways. Thanks in advance guys!

 

Check the connection to the intake. It's opposite the throttle body on the intake. there is a little T coming off there and that's where it connects.

 

check your pressure source...it's probably come off...and also inspect your vacuum tubing.

 

if it was workin and now it isnt its probably just something simple like the vacuum hose is off at either end. If not then its possible the gauge is bad but ive never heard of a mechanical gauge not working like that.
