Check for problems with the starter, either a loose wire or the starter is bad.
First thing to check is the connections to the battery, and then the battery itself.
The heavier the load you try to pull from a battery, the more it can be affected
by dirty connections to the battery.
The radio may be the lightest load of all. The radio will run even if the battery posts are
caked with goo and grime and one strand of wire pokes through and makes contact.
By far the heaviest load of all in a car is the starter. And plus, when you're starting,
the car's alternator doesn't help a bit electrically because it's not running yet, so it
ALL has to come from the battery. If there's a loose clamp on one battery post, or
dirt built up on them, or some broken strands in the cables connected to the battery,
then the juice literally can't get from the battery to the starter fast enough to run it.
One at a time, disconnect each clamp from the battery, clean the battery post
and the inside of the clamp with a wire brush and some baking soda or abrasive
cleanser (Ajax, Comet) in hot water, dry it off, and reconnect it good and tight.
If it doesn't start up right away, remember that in order to charge the battery,
the juice has to go in through the same places, so make sure the battery is well
charged before you decide that cleaning the contacts didn't work.
Two good reasons to try cleaning the battery contacts first:
#1). It's a common cause of what you're describing.
#2). It's the cheapest, easiest fix to try.
one word. starter..
Check fuses , or bulbs in radio burn out.
broken circit in your light switch
Ma key wont turn over because i took the factory radio
There may be a problem with the relay on the ignition switch. There may also be a problem with the battery it may be have enough juice to run the light and radio but not enough to turn over the engine.
Does the engine turn over ? Is the timing belt in one peice ? Faulty distributor ?
if all the other electronic parts work such as lights and and horn then it's probably a starter selinoid!
if the car does a click like it is going to turn OS but wont then yes it is the starter
