The cable or wire(s) is loose and need to be tightened.
I don't think you can even have a starter that doesn't work. If you do have one that doesn't work, there is something wrong with your game most likely.
Probably a losses connection, try tightening the terminals.
A weak battery. There is not enough voltage to hold the starter solonoid in.
Wires connected to the starter incorrectly or defective ignition switch.
Start with the basics. Is the battery fully charged? Are the battery post clean and tight. If you answer yes to both of these and the engine will not turn over and you hear nothing, suspect the starter, starter solenoid, or ignition switch is defective.
Get a new starter. It's gone bad and is trying to draw too much power and can cause a fire.
There are two SMALL wires on the starter. They are connected wrong.
you hjave a short in wiring. check the connections at starter motor to make sure they are tight.if they are tight then you should have stater motor repaired. the starter is the only thing low on the car that would spark when trying to start
bad starter
Does the engine crank over?
you have a dirty battery post
why were there sparks when cabels were hooked up when trying to jump start car is it safe to try and jump start car again
your starter is bad, just replace it.
check the alternator
the solenoid on your starter is finished, replace the starter......
compression test
Batteries low. Starter's getting current but not enough.
Bad starter, bad flywheel/ring gear, bad starter/flywheel alignment.
it might be your starter.
