Well, I started out this morning ready to perform trouble-shooting and take pictures. After locating the fuel pump relay under the power distribution box, under the hood, on the passenger side of the vehicle; it dawned on me that I still don't know if you have the 4.0 OHV or 4.0 SOHC engine. Is our battery on the driver's side or the passenger's side?
Your reply in #16 leads and your replacing the relay leads me to believe that the problem is in the control circuit. When you put the jumper in the inertia switch connector, did you check it with the test light. It should have come of 1-2 seconds when the key was switched on. From my reading on your #16 it did not.
To answer your question regarding jumpering the relay (looking at the diagram AND you have the 4.0 OHV engine), the jumper would go between the contacts corresponding to C109 (BK/Y) and C100 (DG/Y). Your pump should come on. Do this only for a short period, you don't want to fill the cylinders with gas. I'd feel better if there was a picture so the correct pins are confirmed.
