By again-probing the connector and searching for the right voltage and floor alerts, you are able to determine In the event the Command module is working. By the way, GM has normally used the exact same wire shades for these circuits.
Ignoring these signals could lead on to a lot more critical problems down the road, for instance motor hurt or full fuel technique failure.

If fuel technique strain is low only below load, that doesn’t instantly suggest there’s a thing Incorrect While using the fuel pump. Sure, a clogged filter can result in reduced strain and minimal quantity less than load, but low voltage in the fuel pump connector will do the same point.
This could be resulting from a worn-out fuel pump motor, which can cause the pump to work more difficult and make additional sounds.

What comes about once the engine can’t get the correct level of fuel? It’s heading to start sputtering, Specifically for the duration of acceleration.
If tension would not boost in the event the duty cycle is commanded higher, both by way of a scan Software or at wide-open-throttle on a test travel, This might reveal a defective pump. If fuel pump obligation cycle stays significant at idle just to take care of ordinary tension, this may suggest a foul fuel pump motor.
