Hello

If the car's not cranking then first check it can turned over by hand so double checking for anymechanical issues

If OK then check that the main battery cablesare on tight and the terminals are clean and bright. Do the same for the engine/ gearbox earth strap.
Then follow the main positive lead back to the engine and down to the startermotor, and check the connection at this end as well.

There should alsobe a small wire to the motor which should have 12V when you're turning theignition switch to crank. If the 12V isn't there, check back along this wirefor damage to the insulation or corroded connections

This 12V feedcomes directly from the ignition switch so this may be faulty and needreplacing

Check theresistance of the main positive lead that runs down to the motor as anythingmore than a few ohms and it should be replaced

Don't forget totry a jump start from another car / battery as its possible the battery ispoor, if you have a voltmeter a healthy battery should read 12.7+V

also trysubstituting the battery for another as I've known a very flat battery to dragdown the system voltage too far even with jump cables

one other thing to consider is that the immobiliser is faulty and preventingthe starter from being enabled - however if the dash / ignition lights are onthen this usually means that its off

If this is all OK then its possible the car needs a new starter motor

all of he things you mentioned have to do with my starting system and it is a possibility that I fried them or my battery so long enough to make technically go bad

that is possible

try just charging the battery as the 1st step
