Relayboard Fuel Pump port issues

I am working on wiring up my ms system and having issues with the fuel pump, Am I correct that the FP outlet on the relay board will supply enough voltage to the fuel pump to run it when the computer deems necessary? I currently have the system insalled with the positive side of the pump directly wired to the fp port on the relay board but its not turning the fuel pump on. Starting to get a little frustrated with it.

It should as long as you have a sufficiently large fuse.
Have you checked the fuel pump output on a Stim?

I have a 40 fuse in the slot, I have checked it on a stim and it works as it should on the stim.
I think its a power issue to my box, currently I have it wired into the factory fuse block, Im going to run a relay with and full battery hot directly from the battery and see if that helps with my issue.
