No Boost!?

[fredleysir]

OK, I just installed an AutoMeter Ultra-Lite 30vac-30psi mechanical boost gauge. I get a reading of 20 in-hg vacuum at idle. When I give her gas, the needle goes up, but never goes past 0. I can hear the turbo spool up, and the needle will go up... but it will not go over 0 into the boost readings. It drops when I shift and everything...
Someone please tell me I just hooked the gauge up wrong. I tee'd it off into the line that goes into the fuel pressure solenoid.
I hope I don't have a boost leak! Can anyone help me!?
Thanks!

Moved to problem diagnosis.

Thanks, sorry about that.
Can anyone help me out?

maybe you got a faulty gauge...or a vacuum line could be pinched.

When I looked at the set up, I decided that a pinched hose could be a possibility. (I can't see the hose in every spot due to how it's installed.)
To let everyone know, I tapped into the hose coming off the fuel pressure solenoid (the one going out towards the front bumper.) Is this the correst hose to tap into?
Would a pinched hose still give me the vacuum readings, but no boost readings?

So I tapped into the wrong hose. Thanks everyone for the help.
Wow, I really suck at this car modification thing.

if you realy don't know what to touch, boost leak , vacum hose , spark is ok on idle ,but when you driven and car won't make boost .Look for Power tranzistor on the Int.Manifold ,of course i thing Maf is ok too and fuel

Can a kinked vacume line on ur boost gauge show proper vacume but bad boost readings?


Thanks!
