I hear a click but no start when turn ignition what might be wrong

Hi. If the click you hear when turning key to crank is from a relay start there. The fact you can hear the click means the ignition barrel is doing something and probably OK.

Oil light is normal. Weak battery is first to check. Next is starter replacement.

the relay should not have any power to it. i would think there is a sort some were on the ignition. i would check the ignition wiring and make sure its not damaged or assembled wrong. relay should only get power when the key is in ignition and turned to start engine.

check for lose wire connection off wires on solinoid and battery solinoid is connected on stater motor normally on the side off engine at the back off engine

check your starter,better yet has your alarm system been activated and possibly shut down your car a passive alarm will do that

You say it won't turn over. Then your problem is with the battery, ignition switch, or starter. If you hear a click, click, click, then the battery is dead. If you hear nothing then it may be a bad ignition switch. Turn on the headlights and then attempt to start the engine. If you hear a click, the lights dim, and it will not turn over, the starter is suspect. Check the voltage at the battery with a voltmeter set to DC voltage on the 20 volt scale. These are the readings you look for. If your battery is not reading at least 12.2 volts it needs charging or replacement. If the battery is over 3 years old, it more than likely needs replacing. Now if I am missing what you are saying and the engine does turn over but will not start then turn on the ignition without trying to start the engine. You should hear the fuel pump run for a few seconds and then shut down. If you do not, then the fuse may be blown or the fuel pump relay may be defective. The fuel pump itself may also be bad. You may have to open the fuel filler door and remove the cap and listen at that location while someone else turns on the ignition in order to hear the pump running.

Sounds like a loose battery terminal, when you slam the door it shakes the car and in turn makes the terminal connect. take off the battery terminals clean them and re attach, see if that helps.
Good luck.

Check your battery terminals and the hot lead on the starter make sure they are clean and tight. If they are you are most likely will need a starter.

Either the battery is dead or you starter is bad.
Have someone give you a jump, does the car start now ?
If not please let me know.

It could either be a BAD starter or a BAD ignition they both would have the same symptoms of a "CLICK" alone. I would most likely lean toward the ignition because the key is difficult to turn but its not all ways true that key is tight because the ignition is bad, although possible. It could just mean a bad ignition cylinder(just the key part why its tight) I want you to do a test for me. With clutch engaged turn key to start position and listen for click on starter in the hood, when trying to start. If you hear starter click then the ignition switch is good. (Before you do this make sure that battery is FULLY CHARGED).STARTER IS AT FAULT. IF no clicking is heard coming from starter check starter fuse and if its good YOU have a BAD ignition switch.
