No Secondary Boost - Troubleshooting
So after going to the poor man's non sequential, I decided to go back. After reviewing the diagrams everything seems to be hooked up properly. When applying 12 volts to the solenoids (wastegate and pre control) I hear them clicking, verifying operatrion.
Then I came across this:
CHECK VACUUM TANK'S STORAGE ABILITY W/ENGINE OFF
- PULL OFF VACUUM HOSE AT CHARGE RELIEF ACTUATOR
- SHOULD HEAR AIR ENTERING HOSE VACUUM (Did the test and it checks out OK, actuator pulled in, once you remove the hose the actuator extends outward)
- START ENGINE - BRIEFLY ACCELERATE ENGINE TO WOT IN
NEUTRAL AGAIN
- ENGINE OFF - KOKO 6 TIMES
- WATCH CHARGE CONTROL ACTUATOR WORK EACH TIME (I see no movement when doing this)
- WATCH TURBO CONTROL ACTUATOR WORK EACH TIME (I see no movement when doing this)
Now if I dod the KOKO and see no movement what exactly does this mean?
thanks
chris
