WON`T START 2000 FORD IS IT BATTERY??

clean battery posts and cable ends and make sure to tighten securely when done

if the car will jump off doesn't matter what AAA said battery is bad, either terminals are excessively corroded, or battery has a dead cell internally, remove battery and take to a reputable auto parts store or repair shop and have tested, also have load tested it is bad.

could be the starter relay .

You may need starter:

please give more details..

will it start with a jump ? if it does replace the battery and have the charging system tested, if it will not start with a jump then most likely you will need to replace the starter.

try charging the battery first and then try starting with a jump start ,this will eliminate the starter motor if it works

I would try and jump start the car -- it sounds like the battery might be bad or low on voltage ( due to the cold or age ). if jumping the car works - make sure you test to make sure the alternator is charging properly.
plus this also could be a bad soleniod or starter motor --- but try the jump start first or a new battery.

Check your battery voltage when the car is not running. Check voltage again as someone else holds the key to START. Check voltage again after you've jump started it. First reading sould be about 12.5 to 13 volts. Second reading should be greater than 10 volts, and last reading should be 13.5 to 14.6 volts. If first two readings are low, your battery is not charged, or won't hold a charge (defective). if the 'while running' test is less than prescribed, then your alternator is not putting out enough voltage to charge your battery and should be replaced.

That noise is probably the starter solenoid rattling because the battery charge is low. Start out with a jump or make sure the battery is fully charged up.
