SOURCE: NO START
This problem can be three things. The ignition switch is a good place to start but its under a recall and you should not spend any money on this repair. The passlock system next to ignition switch should probably be changed at the same time and is also under a recall. The instrument cluster is the most probable in your case. The reason i say that is because the key is the headlights not turning on you may also have some lights on the instrument cluster flickering on and off at weird times.The speedometer or other gauges are probably not working all the time. if you are handy you can remove the cluster and send it out for repair. The tech who repairs this might even tell you that the instrument cluster has nothing to do with non start issue but it does. the passlock anti theft reads the ignition key when you insert it into ignition cylinder. Once you turn the key the ignition sends a signal through the instrument cluster to the pcm. the pcm will allow the car to start if the correct signal is recieved. If the pcm recieves no signal it allows the car to start for a second and then kills the car.

Testimonial: "i changed the instrument cluster and yes this was the issue.. its great... thanks.."
we checked.....the fuses, all of the wires from the instrument panel, and the grounds from the cluster connection to the fuses and all seemed to be normal. We couldn't find the main master ground, but all of the wires from the cluster seemed to be grounded correctly. We think the problem has to be the custer going bad. it has 126000 miles on the instrument panel. We have another ordered, but only because that is the last resort to fixing the problem. I know it is a weird temp fix, but my husband found a mild tap on top seems to jolt it just enough to make it start working again for a short while until the new cluster arrives.

try another key. if this doesnt work the wire in the tumbler assembly most likely broke and you will need it replaced. ( Ignition Switch)
