when i try to start my car the key just free turns with no sound at all what do i need to do

Does the key feel right, turn to 'start' and return? Or am I misunderstanding your question..the no sound meaning no sound of engine trying to start...or no sound, clicks from switch and it turns freely? Does not return to 'run' from 'start?

i free turns ... all the dash lights comes on but it wont start

and no it dose nor return from run to start

All I can think of is you got a bad switch. I Googled the problem and looked at some forums, but here is something.. 1996 Taurus GL. I let someone drive my car a while back and they tried to pull the key out hard enough to remove the plastic around the metal. It's a non-transponder type so no bother there. Since then the key has been getting stuck in the ignition on occasion. Yesterday I went to turn the ignition and it felt like something broke. The cluster panel came on and the ignition moves freely 180 degrees and will not start. Thinking it was the ignition lock cylinder I purchase a new ignition from a local Auto Zone that already had the keys cut. The one that matches mine with the plastic shroud and non-transponder. Removed the old ignition and popped the new one in. It moved as freely as the old ignition but started the car. I wasn't able to turn the car off with the ignition as it moved freely without any pressure and was able to remove the key with the car running. I called the local Ford dealership and asked them what their opinion was and they said it sounds like something is broke in the steering column. http://www.fordtaurus.net/forums/viewtopic.php?f=33&t=13486

come to the conclusion that i have a rod in the steering column that is broken...do you know what rod i am talking about and what it is called and where i can find a replacement rod?

What did it end up being?? I am having the same issue.

I'm having the same problem. Is it a rod in the steering column or ignition switch

left key in switch free turn what can i do 1997 frod taurus

broken ignition switch actuator rod. had same problem in 96 mustang. doing one in 03 Taurus as we speak

Very helpful glad I seen this n took time to read it having the same problem didn't know what to think . thank God I didn't by nothing or make a move . this is a gud look tho

2004 Ford Taurus when I turn the key it starts before turning it all the way. Any body know what's wrong?

Ignition acculator is broken or come apart and I am looking atm as to which wire i got to put a switch on just to turn my car on and off since it was last turned on and left in run before it broke.

Just make sure that the transmission is in the park position. This can happen if you are trying to start it from drive etc.
