My 2006 Faord Taurus will not start - turn the key and all you hear is ticking sound in the dash. I can turn the key backward to get dash power for radio, etc., but nothing but ticking when turning the key forward.

U have an unservicable silonide it sounds, but clean terminals on the battery first and check for voltage if u have a multi tester for proper voltage............If everything works out fine with the battery then it may be the silonide........U can also cross out the silonide with a screwdriver....You will fint the silonide by tracing the pos terminal from the battery..........You will have some sparking at first, but if the starter ingages it is the silonide...Hope this helps.

I think yopu have a flat battery
