Block heater plugged in for 1-2 hours will help. Have you determined the GPs are nuked or just guessing since they do not work. How long does the WTS light stay on..... have you tested the GPs with the 12V power and test light.

On 85 engines the glow plug system was the old style system.
Very common for the controller to fail with the glow plugs turned on when not needed which burns them out.
Replace them with Motorcraft/Beru ZD1A glow plugs. Then remove the purple wire from the glow plug controller.
That will disable the stock glow plug system, so you have to use the push button switch to heat them.
In the picture, the purple wire is cut and a green one is spliced to it.

try marking wires and just redoing it or maybe try to get a new one or a good one from a junk yard if you can find one.it would be a pain but may or may not help.rewiring it would be a good start some of the wires may be oxidated and not allowing a good connection
