You need to perform well thought out tests.
First we must know if the pump is powered by simply turn the key in or if it is oil pressure feed or some other switched source. No use banging your head against the wall for nothing.
Is anyone sure of this or can check a manual?
Then start methodically tracing wires back looking for power util you find it. Now what is causing the power supply to stop at that point.
Step by step, no guessing or tossing parts.

|tim2||My 94 did the samething and I thought I had checked or changed everything. Someone from another site told me about a connection on the firewall near the battery. It is another relay, I unplugged it and cleaned the age old crap out of it, let it dry and put it back together. I have not had a problem with my pump since I did this. MIght want to give that a shot.|

Try running test leads (with inline fuse of course) from battery to pump just to check. Then start making sure you're getting power from the plugend that would connect to the pump.
If you need an online manual with diagrams and troubleshooting PM me.
Recently I repaired a friends Cherokee when he had no power to his pump. I found that between the inner fender and firewall under the brake booster a rodent had chewed through the wiring harness.

Fuel Pump no power please help! I have trouble shoot everything!
Ok guys, well this is my third fuel pump here is the story:
Jeep died the other day it seemed like symptoms of the pump so I changed it out and worked like a charm back on the road 2 weeks later same symptoms so I thought to myself ok maybe bad pump switched it out. On the road again for one day then went again, so I decided to get another pump stainer and filter changed all of the out and now no power at all to the pump. I decided to trouble shoot, switched out new relay and fuses (still no power) checked all wires and they are all good no nicks or cuts, checked the ground near the E break it was good, I am getting power to all wires yet still no power to the pump! I am out of ideas... Your thoughts?
