wont crank

First thing that comes to mind its the starter motor,or the starter motor relay,but could be a few different things causing that,could be as simple as the connector on the starter motor could be dirty or not broken. Thats where i will start make sure that you got juice when you turn the key on the starter motor,if so you can tap the stater with a light hammer or a piece of wood to see if turns... Do you hear any noise when you turn the key???any clicking???

trys to turn over but wont makes a noise like its trying no clicking and okayi will try the starter

still wont crank

Wait a moment the engine turns over when you turn the key on ,or not??? If the engine turns over but doesnt start. First do you have any engine light on the dash on? Second make sure the gas its actually getting to the injectors? Make sure you got spark on the plugs? And last check the engine compression? If you have all those 3 components okay the car should start even for a few seconds.
