lift pump issues

Replaced lift pump with a carter and if i hook it up ba kwards it runs fine ut when i hook it up right it wont run
Is this due to not enough amperage or voltage from ecm
Only getting 8.8v
Would putting a relay in line using ecm voltage as a trigger work

It comes with a carter, installing a relay would work but why you are getting low voltage would be a better idea. If bought from Cummins they come with the correct connection, if you put on the duetze connector you can just open it up and switch the wires.
Just a thought!
