Pontiac U0109 Lost Communication With Fuel Pump Control Module
And your "pee" codes follow.

P2078 code definition
Intake Manifold Tuning (IMT) Valve Position Sensor/Switch Circuit High
What the P2078 code means
This code will set if the Engine Control Module (ECM), or Powertrain Control Module (PCM), detects a problem with the position of the IMT valve.
What causes the P2078 code?
This code is set when the ECM sees a higher than expected voltage from the IMT position sensor. This can occur if the circuit has a short to power or a bad ground.
