It shut off while i was turning. now turnes over but wont crank

Won't start how ? When turning the key to start does the starter spin the engine ? Crank - no - start or nothing happens , no - crank - no - start .

IT IS LOOKS LIKE A FUEL PRESSURE LEAKING INSIDE THE ENGINE OR DEFECTIVE FUEL INJECTOR LEAKING . TRY DISCONNECTING THE FUEL PUMP RELAY. AND CRANK THE ENGINE IF ALWAYS CRANK WITH OUT OF FUEL (CRANK WITHOUT START) YOU HAVE FUEL LEAK INSIDE THE ENGINE
REMOVE THE INJECTORS RAIL UP EVERYTHING CONNECTED,PUT BACK THE FUEL PUMP RELAY TURN THE SWITCH ON AND FIND WICH ONE IS LEAKING. (GASOLINE IS FLAMMABLE TAKE CARE)

Engine will not crank (Turn over) ??

Does the starter crank the engine over? If so, check for spark on a spark plug wire when cranking. If you have a strong blue spark, ignition is probably good. Check fuel pressure. Do you hear the fuel pump turn on for 2 seconds when turning key to on?

So the car will crank but not start?

check fuel pump relay, is fuel present at motor 

May have dirt on crank angle sensor ,loose/damaged. Located usually close to bottomf pulley on engine.. Remember to keep it simple and check for the obvious first (fuel/pump? is emergency shut off tripped accidentally from towing ? Turn ignition on and have someone listen at fuel neck for pump operation. Check all fuses.

distributor module needs checking!

Check your throttle position sensor. If it is bad it is telling the computer that the engine is flooded and not letting it get fuel.

change crank sensor and renew thermostat,once ok drain some water and add antifreeze
