Problems with the Starter

Why wont my Jeep start but the radio and lights work? ›

If your car won't start but your radio works fine, you might be dealing with battery issues, starter problems, or a faulty ignition switch. A clogged fuel filter, faulty fuel pump, and worn-out spark plugs can also prevent your car from starting even when the radio works fine.
