1997 Chevy s-10  Blazer, When you turn key on, dash lights turn on & you can hear the fuel pump kick in & it will start, but lately you turn key on & dash lights do not turn on & fuel pump does not kick in & it will not start. The ignition switch seems to turn very normal , not sloppy. But it seems like it has to be something to do with that ignition switch. Also when you turn key on & it has no dash lights & won’t start, radio will play & temp gage above head works!!!!   HELP ME !!!!!
