'96 cherokee sport 4.0HO Will not start

Hi everyone,
My 96' Cherokee wont start, it worked fine one day and now it cranks, sparks, but the fuel pump will not come on. I've checked the ASD relay, Fuel pump relay, all fuses, CPS, new fuel pump (tested this on a raw 12v power supply) and all test ok. There is no trouble codes to be found. Any ideas?

There is no power to the to pump side of the harness, however the sending unit side is fine (meaning gauge works), although i do know thats a different circuit. Also I do have a semi-good Chilton book I have been working from. I think today will be a long hot day in the california high desert.
