By back again-probing the connector and seeking the correct voltage and ground indicators, you are able to determine When the control module is Doing work. Incidentally, GM has generally utilised the identical wire hues for these circuits.
When accessing the fuel pump, it is crucial to Stick to the maker’s Recommendations meticulously.
In-tank electric powered pumps perform the identical perform as external pumps, but are mounted Within the fuel tank, as being the title indicates.

Both equally diesel and petrol engines are IC engines. Which is, both use an air-fuel combination that powers the automobile immediately after ignition.
If force won't enhance once the duty cycle is commanded large, both by way of a scan Resource or at huge-open up-throttle over a take a look at travel, This may suggest a defective pump. If fuel pump obligation cycle stays significant at idle just to take care of usual force, this also can reveal a nasty fuel pump motor.
