2000 ford taurus leave it outside will not start put it in garage starts fine could it be drawing dampness

Did you take the distributor cap off and see if it has moisture inside ?

could be a frozen starter,if not see if the anti theft light is on, if so leave the key on for 10 minutes and see if it goes out then try starting it,its a trick used on aleros mabe it will work on a taurus as well

have you changed the gas out in the tank. the gas will go bad and lose is ingnition properties. if this still doesnt work change the fuel filter.

Do a scan to get codes

Could it be the fuel pump? If you let it sit for a bit then turn the key on and listen for it to pressurize the system you can tell if it's working or not.

try changing the fuel filters if you havent already. Assuming your getting spark it should start if you also are getting furel.

spray your distributor wires and cap with silicone spray. If this does not work you will have to replace distributor cap as it will have a hair line crack in it.

is it petrol if yes then maybe there is damp getting in, r u in a damp area check disi cap and leads

I have a 2000 Astro had the same troubles.I saw that the sides of the coil were burned looking.In between the bar that goes around it. This started around 110K It would run badly when wet or high humidity.Then throw up the check engine lite.Put on a new coil so far the problem has no reocured.

You must live in the cold area, if the temperature is low outside than the garage, the engine start harder.
