Car fails to start.

Try getting a friend to boost start your battery with his vehicle and see if your car will crank. If your car cranks over - you have a faulty battery.

Check your battery leads, particularly the black earth lead where it connects to the engine/bodywork.
It's worth pointing out that a failed battery will charge up to a certain extent - however there isn't sufficient power in that battery to crank the engine even though all your dashboard lights are illuminated.
Get somebody to try boost-starting your battery first.

If you're sure that your battery is ok (or if connected to another vehicle): Put your ignition key in and turn it on/off a few times. Leave it in the 'on' position for 2-3 minutes. Give the system time to re-recognise the key

It actually sounds to be battery problem
jump start vehicle Google Search

fuel and fire, charge the battery, turn on ignition and listen for the fuel pump to pressurize the fuel lines. If you ran out of gas you may have fried the fuel pump.

What makes you think the battery is charged sufficiently? My guess is that your battery doesn't have enough power to crank the engine (just because all the lights come on doesn't mean the battery is good enough to crank the engine). Try jumpstarting the car, or charging the battery. If your car starts, then your battery is getting old, it's time to replace it.

Alternator has failed, make sure the belt hasnt broken off it, when a alternator fails the battery no longer gets charge and it runs off the battery,running off the battery you dont get that far

Sounds like an alternator problem where the battery is not getting charged sufficiently to keep the vehicle going. If the battery and alternator are replaced at the same time, this is probably a good fix.

Is the battery or charge light on when running? Does it light up when the ignition is turned on but before running? The latter would be normal and the former would mean there is a bad alternator or slipping belt.

Good luck on this repair.

Is there power going to the starter, if so then check all the grounds. If not then you have a bad ignition

Sounds like you need to replace the battery,the battery can have enough power to run lights, stereo,and other accesories but it takes alot of amperage to power the starter motor, so if that is the case you will hear the starter solenoid clicking but no action from the starter. Good luck. !

replace the battery with anew one and go from there

Make sure you battery is fully charged, and make sure that your alternator hasnt went south...

Battery or Alternator could be junk...
