My 1997 mercury grand marquis has a brand new battery and starter and still won't start unless i go under car and jump start starter with a switch...why??
Things to test: Ignition switch, neutral switch, starter relay.
Yep, power is not getting to the starter solenoid. Check your fuses too.
Thanks,I'll check those
