1995 ford windstar funs good in cold weather no check engine light gets hot but not by guage shuts off replaced coil pack fuel pump and a few more sensors just can't find reason

same here and still going wild havent you noticed it only does this when the weather is hot, am not sure but i think its the printed circuit board that causes the problem it expand on hot weather and contracts on cold weather, i have tried taking the whole assembly and cleaning it, it did last a few months and back to being crazy again. also considered replacing, cannot find a new one

Check the power feed for the pump at the fuel pump relay. Pull the relay out, and with a test light clipped to a ground, probe all the terminals that the relay plugs in to. One terminal should be hot at all times. If no terminal has power, either a fusible link off the battery has failed or a maxi fuse has blown-check a wiring diagram to see how the relay gets power to it.
If the relay has power to it, check the other relay terminals with the engine cranking. When cranking the engine, two terminals should have power-the fuel pump feed, and the signal from computer to activate the relay. If both signals are present, check the pump wire from relay to tank, check the fuel pump ground, and check if the coil side of relay has a good ground-signal from computer goes to coil input side, the coil output terminal should go to ground.
Good luck. Post back with what you find.

Thanks for the vote, and good luck!

I would probably start by replacing the upper hose. The temperature guage and heat will be affected by poor circulation of coolant.

DIS ignition, no distributor to " get in there " with....

Sounds like your coil pack is going bad. When they start to go bad, they will fail when they get hot but when they eventually cool down the car will run as normal. I would replace your coil and that should take care of your problem. Thanks for using FixYa!

Don't replace the fuel pump. More than likely it is your coil pack. As they start to go bad the heat will cause them to not work properly until they cool down. Replace the pack and that should fix your problems and save you some $ on the fuel pump. Good luck. Thanks for rating my response and for using FixYa!

remove the coil pack and look at bottom of it if it shows any cracks coil is bad very common on these vans if you have a noid light check for injector pulse on #4 if you have pulse and good blue spark most likely the injector is bad you have to remove upper plenum to get injectors out let me know how you make out

change fuel filter if you have then change fuel pump

The most common cause of this condition is the check valve in the fuel pump failing, to check this hook up a fuel test guage to the fuel rail test port, run the engine for a moment and shut it down, after shout down the pressure should stay within 5 PSI of the pressure at shut down after sitting overnight, if it doesn't then the fuel pump must be replaced, the reason is the fuel drains back to the tank if the valve is defective, so you get air and no real pressure on cold start, A check of pressure on a hot running engine will not show this fault, also make sure you are usine the correct Octane of fuel, Prem fuel in a regular fuel engine will cause cold start and stalling issues in cold weather.
