You can test the ignition switch before replacing it. You need a volt meter....not a test light....you wanna see
how much voltage is there. Check the purple wire on the inside terminal of the solenoid. With the key in the "Start" position, you must have 12v. If you don't see a minimum of 10.5 volts there, then you may have a bad ignition switch, neutral safety switch, or wiring issues. If you
do have 12v there, then the solenoid is prolly crap.
This is assuming, of course, that you have power to the rest of the car....headlights, interior lights, etc. If not, then you may well have a burned fuse link, which could cause the no crank problem.
