Hoping it's not the PCM

[Broken6356]

I picked up a 2000 ranger last spring that had been sitting for a couple years, 3.0, manual, 4x4. Started working through some regular maintenance. Before knowing i had a trouble code i did plugs and wires because power on the highway was inconsistent and i discovered a plug wire was loose and arcing to the plug. After finding the trouble code, P0305 i replaced the coil pack and thought it was gone but it came back. Engine would ping a little under load once warm, ran great cold. We had a cold morning, first time in the 30s and after starting my truck and waiting for the fast idle to drop before leaving and after it did, then it almost stalled and started running real rough. I wondered if it would pass but the engine quit just a block from my house. Wouldn't even turn over. After getting it home, found the fuse for the PCM was blown, replaced with new. It now turns over but wont start. Fuel system primes and pressurizes. I thought i was getting spark but realized that 1 of the 3 coil doesn't work. Not getting spark for 2 and 6. Installed the old coil pack that i still had, same result.

Assuming i need to get a new PCM but wanted to ask if i should consider anything else.

I would consider why the fuse blew? Is there a wire rubbed through somewhere? Do you remember which fuse it was?

fuse 19 in the central junction box , 25 amp, feeds all 3 sections in the coil. the radio noise capacitor is also on that circuit.
at the coil rd/lg is the input power.
the 3 outputs are tn/wht for #1, tn/og for #2, tn/lg for #3

power is applied to all 3 coils constantly.
the PCM grounds the individual outputs ( only then will current flow) one at a time to fire that section of the coil pack.
