cranking means starter and key are fine;
have you checked the fuses, yet? 95% of the time, that is all it is.

Yeah, check all the fuses.

Had a similar issue, and it was the Injector fuse.

wut i would do is check the basics first. number 1 the car cranks so u know your ignition all the way to ur starter is good. number 2 is do u have spark. pull the spark plug wire n remove the spark plug. with plug on the wire check for spark by holding it to part of the engine block. if thats good then u check ur fuel pressure right at the fuel rail by the injectors. there is a schrader valve at the end. do just like the spark test n perform this test while u try to crank the car. if fuel squirts out the lil valve, which looks like a bicycle tube valve, then u got fuel pressure. if everything checked out, which i doubt they did then u got bigger issues such as computer not allowing injectors fire.
