For the past two days, when I put the key in the ignition, I get absolutely nothing... no ticking, etc. I turn it on and off 3-4 times, and then it starts. Is this a starter problem ? Not sure. Thanks.

Reading sections A and B should help you decide what the problem is:

My initial thought is that it could be an ignition switch or main relay problem. To be sure, however, go through the outlined ignition troubleshooting steps. Begin by making sure the battery is fully charged and cable connections are clean.
