the hard pipe
plastic tube from pump to drivers side solenoid.
plastic tube from drivers side solenoid to passenger side solenoid.
passenger side solenoid.
top of passenger side solenoid cut off with a sawzall. Solenoid electro-magnet and sensor on the side now.
Twenty six, seven, and eight=
sensor cut out. Can still cut more of the metal away. All I need is the small square portion on top. I could cut it off with a heat gun and sharp blade.
Twenty nine and Thirty=
the two sensor connectors. Notice the drivers side is two wires. This is power and ground for the solenoid electro-magnet. Now see the passenger side is 5 wires. Two of them are power and ground for the electro-magnet. The other three are power, ground and signal for the atmospheric pressure sensor.
It is important to place new gaskets and block off plates over the two openings. Then reconnect the passenger side atmospheric sensor to the OEM harness (purple plug) and find a happy home for it. Zip ties will work it is most likely still under the manifold in the end.
You can simply tape off the other two connections (power/ground to pump motor and drivers side solenoid).
Now the list of CEL's that need to be disabled;
Once the CEL's are disabled you can open romraider logger with the key int he "on" position but the engine off. Check your atmospheric pressure reading. If it is good, so are you.
The ECU checks atmospheric pressure against manifold pressure at start up. If the two readings are too far apart, no fuel or spark. This is a safety feature Subaru built in. If the ECU determines that one of the sensors went bad while the car is running you go into limp mode. You wont see it anymore because you turned off the CEL. But the car will not run properly and might not start again after shutdown.
This is what lead everyone to think that deleting the air pump messed up the ECU. It is not a grounding issue. But a sensor issue.
If you do not want to cut the sensor out of the solenoid you could simply get a second block off plate (KS Tech makes one) for just the solenoid. You would have to block it off and leave it in place. Less weight reduction. Still in the way of your turbo (STi style) ad inlet. But better than nothing.
Hope this helps someone.
