Car won't start batt fine,seems like car is in gear ,but is in park,on dash d4 and p light up,tried putting in neutral to start and d4 and and on dash light up won't start won't even click nothing radio and lights all work,thinking maybe kill switch won't let it start as thinks nin d4??

. Remove and fully charge the battery. Most auto parts stores will test and charge batteries for free. Don't assume it is OK. Nothing you have said convinces me the battery is good.

. Test all under dash and under hood fuses with a test light or multimeter:

. Check ignition switch for wear, pitting, or melting, if the problem persists.

My bet is the battery needs replacing.
