Boost Gauge Problem

[blingindubs]

I need some help from everyone here, I was driving my car yesterday and all of a sudden my aftermarket boost gauge just stopped working it just sits at zero now. But my factory one is still working fine. Could it just be it came disconnected or what. And how would you go about fixing this probelm.

Be careful, when this happened to me the vac line to my feul pressure solinoid blew off (if thats where you have it tapped). The guage acted like it was dead but, I simply wasn't getting the raise in feul pressure to match the boost, very bad. If could be something else, but check your connections first.
