Stock Boost Gauge Not Working

[tek_01]

hey all i done a search but couldnt find what i was looking for, here is the problem, when the car is off the needle on the boost gauge is at the bottom (-7) and when car turned on it goes to 0 so that leads me to believe the gauge is working but it is not receiving a signal? possibly the hose isnt connected as it sits a 0 regardless of revs or stopping which should have some vaccum right?

ive never had a turbo so i dont know where to look to see if its connected. btw i have a r33 series 1 so if anyone can point me in the right direction it would be much appreciated

thanks

take a look on the driver side firewall at the top or near there should be a map sensor which has a boost/vac line going to the intake manifold, normally the hose gets brittle a breaks off common as. also check if the map sesor is connected.

when i got my car the gauge didn't work and it was just due to the hose being split. i just cut some of the hose off and stuck it back on. that lasted a few days before it did it again, so i spent 40 cents and got a new bit of hose.

champions, thats exactly what it was! chopped it and reconnected it again with a good end bit. will buy another replacement soon

thanks
