HELP! 1986 engine fire
So my fan caught on fire somehow and melted to the radiator, and my oil and coolant temp werent high. The only damage is the fan radiator and fan shroud, and maybe the MAF. My question is why my car wont start and the digital display wont come up. The radio works and the car wont even crank.

Likely there are burnt out fusible links there after the electric cooling fan fire.

I agree., melted wires usually mean shorted wires. the fusible links probably protected the rest of your wiring. cut the damaged area apart and replace the individual wires, then go for the fusible links.

That sucks ! I just went through my 87 fan system and not only was the fusable link blown but when i directly powered the fan with direct power the wire supplying the power would get so hot you could not touch it and after a few minutes the fan would stop working.
After seeing this post I find myself feeling pretty lucky !

wow,worst than i thought ! change everything related (wires relay and fuses)
but most important, you must know what caused this, it wouldn't be nice to replace everything and suddenly happens again.
Here's a nice Dewitts upgrade fan :

SPAL (?) fans are the gold standard from everything I read. Solid motors that are heavy from big magnets and very powerful to move hi-performance blades for max cooling efficiency.
Was this car equipped with a fan bypass of some sort ? ??
I'd sure undo that fan relay bypass....if thats where this originated. I've seen this result from guys doing the fan over-ride incorrectly and sending voltage to ground.
next time, do the ground wire or put a switch between the temp sensor and a ground...

That single electric Fan motor use on the early 1984 to 1989 C4's or so....
My 87 Vert has the same.........
It draws around 40 amps continuous when the fan is commanded on.
When it 1st turns on it draws 80 amps peak for a few seconds.
I checked one sunny summer day with my my Fluke Clamp On Amp Meter.
Has Peak Amperage readings, and Average amperage measured, along with real time current amperage readings.
I have seen electric fan fires in the past too.
Its more of a common occurrence on Ford Crown Vic Police cars & Lincoln Mark 8's with that Modular V8.
