86 Bll 5spd man, is falling apart.

My 1986 Bronco ll is the only vehicle I have or can afford at this time .
Two weeks ago it started dyeing when it got hot. once cooled down it would start and run fine until warmed up again. I replaced the TFI module on the distributor and it ran good for a couple of days and then the symptoms returned. Any help would truly be appreciated.

Welcome to TRS


I would get a can of Quick Start(ether) starting fluid, or use gasoline.

And do the 50/50 test
When you have a no start, spray some fuel into the intake, and try to start engine
If engine starts and then dies FUEL is the problem
If it doesn't start then SPARK is still the issue

This will save you time and money

Coils can also get heat sensitive, as can wiring.
As wires get warmer they get higher resistance, this is normal, but it does drop voltage.
If a wire or connection gets corrosion on it then that drops voltage even more this could effect fuel pump power but usually effects spark more.

But do the test first to find out where to start

The TFI module is probably the single most likely cause.

It is also the single most heat sensitive component in the electronic system of any Ford.

When you hear hoof-beats think horses not Zebras...
