View Full Version : Problem with Boost Gauge!

My car still runs fine it's just the boost gauge won't work or the vac. gauge. It just sits on zero. Is this ran by a fuse or how do I fix this. Thanks

It runs off vacuum. There is a line that attaches to the back of the boost gauge and the other end on the intake plenum, I think. Check to make sure they haven't come loose or off.

There's a small plastic vacuum line that comes off of the return plenum close to the ACT sensor and runs over to the firewall on the drivers side. Likely this line is broken somewhere under the hood. A bit of 3/32in (I think thats the size) windshield washer hose works well as a repair for a broken plastic vacuum line.

i found there is actually 2 lines going to the boost guage. One comes in from the motor itself, then attaches to the line thats up under the dash that connects to the guage itself. Make sure those 2 lines are still hooked together. I had the same problem when i was putting my dash back together after changing heater cores.
