No start, no fuel pressure/bad fuel pump?

Saga continues. After testing and getting no spark I ended up replacing the cap and rotor. The rotor ended up being bad and now I have spark. The jeep finally started today using starting fluid. The pump is still not working so now I'm down to two possibilities: either the pump itself is bad or something is keeping the pump from kicking in.

Can someone confirm that means the pump is bad? Thanks

Fuel pump has been replaced and after a few minutes of priming and purging air out of the rail it finally started. How about that: fuel pump and CPS bad at the same time.
