Question 3.0L Aerostar won't start

My 97 Aerostar 3.0L has developed a wierd problem. When it is cold (below -10 degC) it will not start. When I turn the key on, I hear the fuel pump relay click but do not hear the fuel pump. Also the light for the overdrive displays off. At first I thought the gas line was frozen but that isn't the problem. If I plug the block heater in for a couple of hours, it will start right up. Also the off light for the overdrive is not on and of course I hear the fuel pump when the key is first turned on. I have changed the Temperature Coolant Sensor but that made no difference.

Any ideas what might be causing this? It runs great after it starts.

Thanks in advance

Re: 3.0L Aerostar won't start

Try your Thermostat...The thermostat is letting cold coolant through when it shouldnt.. Thus your Coolant Sensor senses cold temps and causes the engine to flood itself..in turn the fuel pump will not kick on... Your thermostat should kick on at a certin temp.. but not at startup! it should kick on and let coolant through at around 180-210 Degrees F...depending on what kind of Thermostat it is.. all in all I believe that the thermostat is bad and is letting coolant through all the time even at colder temps... Kinda a crude explanation but, Try the Thermostat....

Have no idea what this is.

I will give your idea a try Fordman. Never changed the thermostat in the 5 years I have owned it. Sounds logical to me
Thanks

I don't recall ever seeing a serious post from pottymouth_1. He's just messing with you.
