Sounds like the ignition switch is out...do you have access to a voltmeter? We can test the voltage into the switch and out, to further confirm this. No power to the coil and no dash warning lamps are key indications of loss of power through the ignition switch, but it could also be a power interuption to the ignition switch. Also, check your positive battery cable, it's prone to loosening up slightly and causing a power loss.
Yes that would be related as well, the shift interlock also will not deactivate without ignition voltage. You need to be sure your battery is fully charged and the positive cable is on tight and not corroded...if that is good, chances are it's the ignition switch..the switch isn't too difficult to replace. You need to remove the lower steering column cover and there's a couple of smaller screws holding it in.
No problem, please press ACCEPT if the advise was helpful and if you have any problems during the repair or have any other questions, feel free to ask.
