No vacumm pressure

[Izzy]

Pretty much explains it, hook it up to a vacumm gauge, reads absolutly nothing. Any idea why? It's gutless as hell.

First question would be, does your engine run? The vacuum pressure is created by your engine's trying to suck in more air than the throttle will allow, if you've got no pressure, you've either got an engine that's not running, a really bad leak somewhere (which should completely screw your engine performance), or a clog in a vacuum line somewhere.

Yes it runs, and only half the engine seems to have vacuum, the ones comeing out of the throttle body has none, but the ones on the left side of the engine do.
