You may have more than one problem.First I would try to start the car while holding the gas pedal all the way to the floor.It may take several try's to get it to start.You may need to see if it has spark.
It wont start
you flooded it
because its on fire
Check the spark plug. It could be flooded. Clean the carb
maybe ignitoin or ignition switch
Battery connections came loose. Oil flooded cylinders. Something came loose.
Water in the in distributor cap. Replace it.
Either your starter or ignition..
Possibly, You have flooded your engine and you have to wait or you have a flat Glow Lighter. Or you'r actual Car batteries are dead!
If the vehicle has a security feature check the fuse under the hood. My 2001 SL1 had that problem. its like a 30 Amp fuse.
crank sensor is bad
Does it Crank but not start? Yes: Replace your Crankshaft Position Sensor. This is located above the starter.
