Do you have an automatic or manual transmission? If you have a manual transmission and the clutch pedal is not all the way to the floor, you won't crank. There is a safety wire on your starter relay that inhibits starting if the auto tranny is not in park or neutral or if the clutch is not depressed far enough. That wire might have come loose and fallen off. It is usually a brown wire. I'd post a pic of the starter relay but they are not uploading.
