Question about Volkswagen Cars & Trucks
Car starte pefectly till yesterday morning. Then it sounded as if battery was flat, but we push started without a problem. drove around yesterday and started regularly. This morning apart from one effort by the engine no response, we tried to tow start car dead as a dodo. No power coming from battery. All fuses seem in order. Battery is 3 years old and never given problems. What about solenoid/starter motor??

No, you should be asking what is my battery voltage. As taken from a voltmeter, a multi-meter, or a digital volt-ohm meter. You really need to know the battery's state of charge before proceeding to question the starter or solenoid. You could have a loose connection somewhere that is not allowing the alternator to re-charge the battery when the engine is running. That sounds to me more likely what the problem is.
When properly charged, your 3 year old battery should show a minimum of 12.5 volts, some people say it must be 12.6 volts, but that is how defined the process is. And that is why you should invest in a cheap voltmeter, a DVOM is best for automotive work, considering all the small current electronics on modern cars. Just see what your battery voltage is-that is the first step in diagnosing. Did you even think of seeing how bright the headlights were? Or watching them when trying to start the engine? If they get real dim or go out altogether, your battery is too flat!
You can easily check your charging system once the engine is running. Put the voltmeter back on the battery when engine is running, and the voltage should now be over 13 volts, 13.5 volts is very good. Most systems run in the 13.5 to 14.5 volts range. But anything over 13 volts means the alternator is doing it's job.

SOURCE: 2002 Taurus won't start.
all I had to do on a sable was to replace the belt but look at the battery there should be a wire coming from the battery going to another solenoid mounted under the hood and then going down to the starter get a 12 volt tester and see if you have power going to this solenoid cause it could be dead on one end and not going down to the starter

not sure about the 2008 model, but the earlier ones had coil pack problems. it looks like part of the rocker cover with around four torque screws holding it down and one multi plug at the end on the n/s of the engine. oh they used to blow the fuse at the same time for the engine management. 30amp dooor pillar/"A"post area.
test by removing the coil pack, fitting the spark plugs into the plug outlets. earth the body of each plug and crank the engine, you shoukld see a spark, if not then there are other tests before confirming the coil pack. let me know how you get on.

sounds like a starter solenoid went bad which it is easier to replace the whole starter assembly then just the solenoid and you can get one with a LLT Limited Life Time warranty.

Try removing the battery terminals and clean both posts and terminals. Coat same with an anti-corrosion grease. Wash your hands after this to prevent mysterious holes in your clothes. Start the engine and measure the voltage at the battery terminals--should read 13.5 to 14.5 volts. Hope this helps.
