Not enough information. Could be as simple as too much corrosion on the battery clamps OR - maybe you're trying to start it using an ignition key that is not programmed correctly OR - a bad ignition switch - bad starter - bad relay in the under hood fuse box - etc. Too many possibilities to pin it down without more info.
OK, it has a battery. What are you wanting to know?
Do the headlamps work while cranking the starter? If not focus on your battery and cables. Jump start the car and have the system tested before you throw more dollar bills at this problem; it could be the alternator but have it tested first.
Press clock, type digits then ok
take them out . you should charge battery then be ok.
You may have a weak battery. Your starter may be bad.
Could be many things. Boot light does not switch off? Radio? Chafed small cable?
check starter
Bad battery won't take charge Bad battery cables Fuseable link
If the battery and fuel are ok, it should start right up.
if battery is ok chech netural saftyswitch
check your battery then the connections if it still wont start try changing the starter solenoid if possible
have starter motor checked. ford starters will run a battery down when swithed off if they are worn out.also check ignition switch Check the fuel pump relay. It may be sticking.
