your continental depending on year should have two (2) starter relays. one starter relay (which usually is the one to go bad) is on the driver side fender well under the hood. your positive battery cable from the battery will lead you straight to this one. replace this relay the car should then start. the other relay or solinoid is on the starter itself. you may have to replace the starter. both are fairly easy to replace. Try Checking the nutral Safty Switch. Turn the key to the start position and shift the gears around to see if it starts (While holding the brake)
Most likely your car battery is completley dead.
Does it turn over? Does it have spark? Fuel?
Replace the starter
If the batteryu & starter are good, I would check the neutral safety switch
its probably broken or not plugged in
the battery may not have enough energy to turn on the lights. an is the engine turning over completely at the rate that it should be or is it struggling to turn? also check all of your fuses
I would start with checking the electrical system. i.e. battery or starter
dead battery or a broken wire between the battery and the starter
First of all is the lights working in the car? (over head lights or any kind of lights) If your not getting anything at all (no lights) then you should check the battery. If the lights are working then I would check your starter. Most of the time if you take the battery somewhere to get checked they will do it for free. So I would start there. Did you try to get a jump to see if that would start it? Hope this helped some.
Pull out on the light switch when you have turned it to the right to turn on the lights.
If it doesnt turn over it can be
try checking the alternator try charging the battery with a car battery charger or getting a jump from a friend's car to get it to turn over
