I have a question that may have a simple answer. If so, please let me know what it might be.
The Volvo is a 1989 240 wagon. One day the car started then quit and never started again.

Car cranks and this is what I have:

No injector pulse,
No spark,
Fuel pump doesn't run either cranking or in #2 position of ignition key

Things I have checked or swapped out with known good parts:

Both computers,
Fuel pump relay,
Checked all fuses and continuity on either side of the terminals,
12 volt fuse on fender near battery,
Coil has 12V on both sides,
All ground contacts cleaned and checked for continuity,
Coninuity checked between battery grnd and block, block and body and battery and body, all little to no resistance,
Flywheel sensor changed,
Power stage,
Coil changed,
Cap and rotor.

I am at the point where I think I need to open the wiring harness up and look for a melted wire.
When the car wouldn't start the first time, it sat for a week or two, then the battery died, odd because it is a good battery. The fuse holder on the drivers side fender near the battery was melted and when the plastic deformed, two terminals touched. This leads me to believe there was a short of some sort. We fixed the fuse holder, but the car wouldn't start. I think there may be a melted wire somewhere in the harness. Is it worth tracing that red wire all the way to the fuel pump relay (I think that's where it goes) or just pull out the whole harness and replace it with a junkyard one?
Or is there something obvious that I am missing?

Any info would be great, as I am at a standstill right now.

Thank You,
Neil
