Starting problem when i put the key in and turn to start it doesn 't do nothing but everthing else is working , radio datch board , lights.  helppp!!

I had the same problem figuered it out on my own under your stearing wheel there is a box connected the the box is a wire ,,, well on the wire there is a switch flick it and away you go

First i would check your battery to make sure it has proper voltage and is fully charged. But it sounds more like a starter solenoid problem. Check the signal wire at the starter solenoid(it's on top of the starter), Whenever you turn your key to the start position you should get power there. If you have power there I would make sure your ground is good and the ground is good as well i would replace the starter/solenoid assembly. On the other hand if you turn the key to the run position and get no signal power(12V)at the solenoid then your problem lays between the key switch and the starter solenoid. hope this helps you out

Alternator. take it off and take it down to an auto parts store and have them test it
