Boost gauge reads zero

[COEBAM]

Hey guys- I did a little looking around about this, and found some threads, still not sure. The gauge lights up just no reading. Does the MAP sensor feed this gauge or is it the vacuum line off the by pass valve? If it is the valve; where is the bypass valve located?

Btw got the coupler kit put in and a new SC belt and tensioner works great. Just trying to fine tune a few things...Thanks everybody!

I installed a plastic vacuum line T to tie into the vac line at the MAP sensor. Should read in the negatives on idle.

depends what kind you got. did you get an digital or analog gauge?

It's just the stock gauge located in the info center.

that is read through the PCM, so id say you have a vacuum leak or your BBV is done for.

Found a vacuum leak under super charger at the little tee. Thanks everyone!

go ahead and replace crappy looking lines. i had several that were unnoticed for a while.
