08 Outlander 800 – P0231 = Bad fuel pump?

Hey all – haven’t been here in a LONG time.. just haven’t been riding much unfortunately.

Outlander 800, 2008 model. Not hearing fuel pump prime when key is turned on, check engine is on, and the code readout is P0231, which according to another post is (P0231 Fuel pump open circuit or shorted to ground). It was fine when I last rode about 4 months ago, been sitting in the garage untouched since.

Is this fairly conclusive of a bad pump, or is there something else I should be checking? Battery voltage is fine – turns over fine and has been on a battery tender 24/7.

Thanks!
