Question about 2003 Ford Focus
Try this procedure:
Check the battery like this:
Turn on the headlights, then try to start the car.
If the headlights do not dim or go out, then the battery is likely ok.
Check that the battery cable plus post, goes to the starter, Minus post to a good ground, like the engine.
If wiring is ok, then look at the starter solenoid for a good connection, and proper voltage at the starter.
Problem is most likely the Solenoid's bendix gear or starting relay, Have someone bang on the starter while you try to start the car. This usually works by dislodging the bendix gear..
Hope this helps.

If you try jumping it with cables from another car, and the starter just clicks,it could be a bad connection to the starter at the solenoid. It COULD also be a bad starter at this vehicle's age.Also make sure the alternator is giving you 13 or more volts at an idle to charge the battery.Hope you get it fixed!

The fuel pump wires are positive: pink/black and negative=black. Pull the connector, turn the key on, and check these with a test light. Your pump power runs through the PCM.

You might have a problem with your crank sensor or ignition. Remove spark plug wire and check for spark while turning engine over. When this happens unplug crank sensor near crank pulley then plug back in to see if it starts if so replace crank sensor.

First check battery cables for corrosion and bad connections check the battery voltage you should have 12-13 volts at the battery then see what you have at the starter where the battery cable is connected.You should have at least 12 volts there too.If you don't have 12 volts at the battery replace battery.
