Watch this video to find the starter relay inside the car.

tap on the starter while someone cranks the car.

You can use some tool to check your car. Car Diagnostic Tool

When you disconnect your battery and then reconnect it again, it disables the radio. This is an anti-theft protection for your car radio.
The enable your radio the activation code is in your vehicle owner's manual. If you do not have this code you need to go to your vehicle manufacturer's service centre and get them to enter this code for you.

Car not starting or turning over indicates towards multiple possibilities. It can be issue with battery or weak battery. But if battery checks out ok, then it can be starter issue or faulty alternator or problem with low fuel pressure or no spark at spark plugs due to dirty spark plugs or faulty ignition coil or injectors getting cracked or dirty and needs to be cleaned.

To confirm the problem, the basic troubleshooting is required.

CHECK BATTERY VOLTAGE WITH DIGITAL VOLT METER.IT SHOULD BE 12.5 VOLTS.IF NOT CHARGE IT OR HAVE BATTERY CHECK OUT OR REPLACE.IF BATTERY GOOD.CHECK BATTERY CABLES FOR TIGHTNESS OR CORROSSION.IF CABLES GOOD.PROBLEM COULD BE FAULTY STARTER OR SOLENOID.TURN OFF RADIO BEFORE REMOVING BATTERY CABLES SO YOU WONT LOSE RADIO CODE TO PLAY RADIO.ALSO HAVE ALTERNATOR CHECKED OUT TO SEE IF IT IS CHARGING THE BATTERY.

If the problem occurs after the car has been driven long enough to reach normal operating temperature, the problem is the starter. If the 'no crank' occurs cold, retest the battery.

Radio could be wired wrong. Check the constant and accy power on the radio with a multimeter and make sure you are getting 12V on the constant and getting 12V on the accy only when the car is in accy or on. Also make sure the wire harness is properly wired. This can happen often if the radio constant and accy power wires are wired in reverse.
