Default 1986 Nissan King Cab SE (4X4 MT VG30) aka Desert Kitten

Hey all, acquired this truck from an acquaintance.

It hasn't been running in about 5 years. I went through the whole fsm procedure for diagnosing no spark back to the ECU, which I'm finding doesn't turn on. Checked voltage at the pins and locations in the fsm but came back to poor fusible links (I went through and resoldered new fusible link wire into the main link), a break in harness (but didn't I check voltages and confirm this isn't the case? Yes), or bad ECU. Still no power on the ECU. Is there anything I'm missing here? PO threw new coil, cap& rotor, etc at it prior to giving up and parking the truck.

How can I check this? Should I grind out a new spot to ground the ECU to? I was not using the ECU ground when checking v+ on the harness plugs

Where the ECU is under the passenger seat there is a ground to the hump that the seat bolts to. That has a tendency to get rusty/corroded.
