1996 Dodge Van Vehicle cranks but no spark or fuel

I've got a 1996 ram van 3500. Currently it will not start. It has been sitting for several months. The battery that was in it eventually died and so I had been jump starting it, but eventually it would not start even with a jump. I recently put a new battery in the van hoping that would solve the issue- it didn't. The van will crank, but won't fire. I've checked all the fuses under the hood and in the dash with a multimeter and they all seem OK. I've checked for fuel pressure by pressing on the schrader valve on the fuel line and get nothing. I've pulled plugs to check for spark and nothing. I've also checked for voltage at the wires that come into the ignition coil and there's no voltage. I'm starting to lean towards the PCM being the issue, but not sure. The check engine light is not on. I haven't scanned for DTC codes because I don't have a scanner. Not sure if that's something I need to do.

Any advice would be appreciated. Thanks.
