Cooling fans work only when ac is on will not come on at hot runnig temperature for engine so you run with ac on at all times is this a sensor problem or fan relay or fan swith?
Well, you listed several of the parts that could cause this problem. The other part that could cause this is the Power Train Control (PTC) module. The PTC is the module that takes the temperature input from the coolant temperature sensor and turns on the fans via the fan relay when the temperature is high enough.
Could the distributor be the problem when the engine quits runnig every 15 seconds on a 3o2 efi engine?

Take out the copper wire and soak in bleach ( Great battery sustainer) and then pull all the way through the hole then close. If your engine doesnt have the knob you can drill a small hole in the corner and pour the bleach…
Daytime Running lamp are usually controlled by a separate module. You will have to find the relay or fuses for the headlights and check them. They are usually in the engine compartment fuse box. One fuse\relay usually controls the low beams and another controls the high beams. That is the way Ford does it anyway. If those are good then the switch is probably bad and will have to be replaced.
Check the folowing 1: Fuels Injector Rings ( Have someone turn the key to ON but not to Crank and watch for leaks) 2: Gas Regulator ( Located on the fuel injector rail ) Cheers Replace the thermostat and change the oil. Same thing happend with mine when I bought one used. Changed the thermostat and the oil and it solved the problem. Gas milage also doubled.
