1997 Jeep Cherokee 97 Cherokee sport died, won't restart

My 97 cherokee sport w/ 4.0 liter died going down the road. My gauges died as well, but other items on the dash kept power, like the radio. I put gas in the car and tried to start it but to no avail(Thinking it might be out of gas because my sending unit doesn't work right all of the time). I checked voltage for the fuel pump and found that it didn't have voltage. I also didn't record voltage at the coil. I had no fuel pressure at the fuel rail. I had no check engine light nor did I get a code after cycling the ignition on and off. While checking electrical connections under the hood, I found that when I unplug the front plug of the PCM, the fuel pump and electric fan both start running. I don't have a diagnostic tool but will consider getting one if that's needed. Thanks for your help!
