The ground wire is melting on the 1990 F150 when trying to start the vehicle because the wrong wire is being used as a ground wire. The wires are color coded. Perhaps the factory made a mistake with how the wires were hooked up.
Ground it to the vehicle frame or engine.
To find the code numbers for troubleshooting a 1990 F250 with cold start issues, it's best to take the vehicle to a mechanic who has a diagnostic machine. The machine will provide the codes which can then be used to refer to the vehicle instruction manual.

Hey tom its a 1990 pontiact transport van and it starts out fine and as soon as the vehicle warms up it will stall it will start back up but when you put it in gear from park it stall again until cool?
I recently had this problem with another vehicle. If the vehicle will crank but not start, it may be a leaking fuel injector. A leaking fuel injector will flood the engine, not allowing it to start. This is especially true if the vehicle will not take a jump start. If you can hear the fuel pump (in the fuel tank) turn on when you first try to start the vehicle, then the fuel pump is working. It generally tries to stay on for about 5-7 seconds. If it will not crank, then it may be your starter. Hope this helps. SD
