My 2005 dodge neon won't start. The alternator went out I jumped it 3 times cause I thought it was the battery but someone told me the alternator so I got it replaced and got the battery jumped then it wouldn't start . When you turn the key the dash lighhts come on makes a click noise once then does nothing. Engine coil replaced , fuses good, wires good. I reallly need help here. My mechanic is lost and so am I

I suspect the battery is bad. Most auto parts stores will test and charge batteries for free. Be prepared to buy a new battery. You also want to clean the battery terminals and cable connections with abrasive cloth. If the problem persists, clean the main ground and the connections going to the starter motor. Ensure the battery cables don't have any hidden breaks or hidden corrosion.

Perform an Ignition By-Pass Test, where you connect a 12 AWG wire, or remote starter switch, from the positive battery cable to the "S" terminal on the starter motor solenoid. If the starter motor cranks, the problem is with the ignition switch, neutral safety switch, or wiring. If the starter motor doesn't crank, replace the starter motor.
