Clicking sound when trying to start
Is the battery charged up? It should be at least 12.6 volts.If you have a voltmeter, do a voltage drop test on the battery cables, posts, terminals-looking for high resistance in passing current to the starter. Bad cables or terminals if you have high resistance. Youtube has videos of voltage drop testing.If you don't have a voltmeter, take the starter off and have a parts store test it for free. If starter and battery are good, check for power on the small purple wire at the starter solenoid with key held in crank. If power there, and starter and solenoid were tested, then could be the battery ground, or a bad battery cable, a loose connection on the starter, or starter not bolted down tight. Maybe the starter and solenoid tested okay, but still not good. That's rare but not unknown.If no power on the small purple wire in start, check the starter relay-is that what clicks? Try a new relay.Good luck, half the time it's the starter, the other half is one of the above. If the click is at the starter, you can assume that the start circuit is good-look to the battery, cables, starter, or a loose, poor ground or cable connection.
