    When you say it wont start....does it at least turn over or crank? If it cranks but wont start, have you checked the fuel pressure to make sure its getting gas? We need little bit more info, the year and engine size would help. Also depending on whats wrong with it the scan tool might tell you what is wrong with it. but if its the starter or solenoid then no. you need to test that yourself or a mechanic would. let us know if it cranks and has fuel pressure also check for spark.

    if it won't crank at all it could be just the solenoid. check auto parts store to see if solenoid is internal or external. if external you can replace the solkenoid. if internal you just have to replace whole starter

    If your 2002 Ford Taurus won't start, the malfunction may come from the starter motor relay, which helps to regulate current to, as its name suggests, the starter motor. Although easy to remove and replace, you should take extra care during repair as the starter motor relay rests in the engine compartment power distribution box--a fuse/relay box connected to high current wires.

    Difficulty: Moderately Easy


    Things You'll Need:

    • Manual
    • Replacement relay

    1. Step 1

      Disconnect the battery. Remember, if you don't disconnect the battery you run the risk of an accidental electrical surge that could hurt you or cause costly damage to your vehicle.

    2. Step 2

      Unlatch the cover of the power distribution box and push up. You don't need to remove the entire lid, as it can rest vertical to the box while you work.

    3. Step 3

      Unplug your Ford Taurus starter motor relay from its socket located toward the back of the box (#23 block on your power distribution box diagram). This relay, one of the first two maxi-sized relay blocks that you can see as you look toward the back of the box, sits to the right of another relay block (#24 fan relay). If you're still uncertain of the location or for other model year locations, confirm using one of the owner manual .pdf files found at Ford Fleet (see Resources).

    4. Step 4

      Check the box area for dirt, corrosion or damage that could cause the relay to malfunction. Clean, fix or repair any area, as needed.

    5. Step 5

      Plug in your new relay and make certain the relay fits securely within its socket, as current running through a loose relay can cause the relay to overheat or the outer casing and surrounding relay casings/box cover to melt.

    6. Step 6

      Push your power distribution cover down until it locks firmly into place. Reconnect the battery and start your Ford Taurus to test the new relay.

      Here is something that might be of some use and a cheaper possible cause that you can test yourself just follow these steps. If this dont work then come back here and let us know..
