Is the battery brand new? This car takes alot of power to start. If your using a battery that has gone dead before or just not fully charged the cars electronics may work without it starting. The car has a safety mechanism where it won't crank if it doesn't have enough power to start. This save the car from over cranking and damaging the starter.

Check headlights and dashboard lights first. If no/minimal power for the lights then replace battery.

Check your battery, it may be weak or dead and needs to be replaced.
Turn the key?
Does the engine crank but not start? Or does it not even crank? Based on the information you gave, you could have a bad starter or weak battery. Dead battery. Recharge it or get a new one.
Discharged battery Bad wiring connection, positive or negative Immobiliser fault Faulty ignition switch.
I had this problem on my 1995.. it turned out to be the crank sensor I would check the battery terminal, did you clean it good when you replaced the battery? Also I have seen defective batteries and to check it put it on a load tester for batteries. I think most parts stores carry them and will check it for free. I would start with that battery terminal first if you haven't done that.
AnswerDim lights and lots of clicks is an indication of too low a charge on the battery. When jump-starting, allow the battery to be attached to the jumper cables for about 5 minutes before trying to crank the engine. If that fails, check for loose battery cables at the battery, ground, or starter. If all connections are good, then the battery is too far gone and must be replaced. Note: You need to find out why the battery discharged - did you leave the lights on? is the alternator bad?.
COULD BE THE CRANK POSITION SENSOR
Yes, the main concern is if the terminals will be on the correct side and will it fit. The cold crank amps is the max current the battery will put out when cold. Your cars starter will only draw what it needs.
If none of your lights work , it could be a battery cable connection or a dead battery
Low battery - not enough power to crank all the way over or, Fuel pump needs to be replaced, not getting fuel into the engine.
