No spark

I have a 1989 Wrangler with a 1995 2.5L the engine just quit and I have replaced the crank sensor, the coil, the wires, the plugs, the cap the rotor and the pick up in the distributor and still have no spark to the plugs. Anyone have any other ideas for me to try. Its driving me nuts

Do you have power to the coil? Can you tell if the fuel pump comes on when cycling the key on? Did you check the ASD relay in under hood fuse box? You can swap it for another relay for a quick check, also check fuses while your in the fuse box.

No power to the coil, fuel pump does cycle and I HAVE SWAPPED THE RELAYS AROUND AND HAVE CHECKED ALL THE FUSES UNDER THE HOOD AND UNDER THE DASH.

Weren't these older YJ susceptible to bad ignition modules?
