2002 LX 470 won't start

You say 'Crank, no start', but you also say 'it will not turn over'. They are the same thing, if it cranks, it is turning over, but not 'firing' or 'starting'.

After you disconnected the battery, did you reset the Security System and Engine Immobilizer? You know it has one, that flashing light on the dash?

Some ideas here

If that doesn't fix it, an auto electrician with a $5,000 professional grade Autel scan tool will be able to diagnose the entire car in 30 minutes. A $130 scan tool is garbage.

The starter is located under the intake manifold in between the twu cylinder heads, the entire intake system has to be removed to replace the starter.

Hi my car won’t start it turns over fine but the immobiliser seem to be kicking in. Was running fine changed the battery an now won’t start. Any ideas?

sounds like a bad starter

those vehicles are common for starters did two today alone when it wont start try to tap it with a hammer it on the back side of the engine under the intake if it starts replace starter

Switch on head lights or cabin light. If they doesn't come on or is weak, the battery is flat. Ensure that you switch off the lights.
With ignition switched on, assuming the lights on the instrument panel cames on and your immobiliser is deactivated, turn ignition to start. You should hear the solenoid at the starter making a click sound. If not, the battery is flat or the starter solenoid is faulty. If it does make a click sound, the battery could be too low to turn the starter or the starter is faulty. Assuming the immobiliser is working correctly, and the starter tries to turn the engine but it doesn't want to turn, the gasket could be blown and the cylinder filled with water, or the engine could be seized.
Hope it is not the last case. MarioCpt

If your battery is known to be fine then you probably have a bad starter. You can pull it and take it to autozone and they will test it for free before you buy a new one.

Possible causes are: 1. Loose or corroded battery cables. 2. Bad starter 3. Dead battery. Try tapping on the starter with a hammer while someone is holding the key in the start position. If it starts then replace the starter. Thanks

put battery on charge for a at least a day if not two before you start interfering with with anything.Sounds like a flat battery or battery not holding enough reserve amperage power.
