I did the troubleshooting from another post, to find out that my turbo is not boosting. Vacuume pump is not working, but my actuator does work.

At idle,with the waste gate fully closed should I here the turbo?
I can hold the waste gate closed and nothing changes.

Thanks

at idle, there is almost no load on the engine, and opening and closing the wastegate makes little difference on the idling turbine in the turbo. So no, holding it closed at idle won't make any difference.

Need to fix the vacuum pump so it can hold the WG shut while driving and then you can develop some boost pressure.

I'm going to replace the pump today.

Installed pump, turbo is working.
Now I need gauges.
