Q: My boost needle quit reading.
A: The pressure sensor gets regulated 5V from the gauge (red wire), and needs a good ground in the engine compartment (black wire), and returns the sensor voltage on the blue wire. Things to check: The needle should go to 12:00 on poweron as a test, then it starts reading pressure. Using an ohmmeter, check the sensor cable black pin to ground.
