It appears you are willing to throw a few parts at it, and see.
Here is one to try.
There are 2 engine coolant temperature switches that screw into the block.
One controls the fan that cools the radiator in the front.
The other is hooked to the computer and tells it what your engine temperature is.
Specifically, it tells if the engine is cold or hot.
When this sensor fails, it will tell the computer that is engine is cold when it is not, and then the computer will make it so the engine will not start.
Sometimes these two sensors are even the same part number.
Try replacing that (computer) temperature sensor, it should be cheap.
God bless your efforts.
