the ignition switch is on the other side from the key. its quite small. you can test with multimeter. $47 at napa. its a very simple switch. the key just rotates it. if you stick a screwdriver in the blue part you can rotate it like the key rotates it and test.

click the above pic to get medium or large picture. if you see the number 3 terminal on the starter switch, it goes to ignition coil and also back to the relay box to give power to fuel pump. if any hot wire is touching this wire, your car will continue running. a wire for example could be loose under the relay box by battery.

do a search because it might be a common cause for this.
