Jeep Strokers

Does anyone have a wiring diagram that shows the whole fuel pump circuit for a 94 yj? My pump isn't priming with the key in the on position, the ECU comes on with the key in the on position, all relays and fuses are new. Given that this problem only seems to happen intermittently I'm thinking that it's a bad ECU, but I want to try to run down any loose connections before replacing the computer.

The fuel pump relay gets its switched power via the ASD relay output.
The fuel pump relay is grounded by the ECM
The ASD/fuel pump relay is triggered by the ignition switch in ign. III and IV (run start)
The fuel pump relay power feed has its own fuse in the PDC.
