The 200 character minimum is to force you to provide enough information or detail so someone can figure out an answer. To start with, put some punctuation in that huge sentence so we know how to read it. First you said it's cranking, then you tried neutral. If it's cranking in park, what is putting it in neutral going to get you? The starter circuit is working. Next you said it "will not stay running" which implies it did start and run a few seconds before it quit. Is that right? If it runs for two seconds, then quits, it is in anti-theft mode. The additional clue is it will not run again until you turn the ignition switch all the way back to "off". Use the remote key fob "unlock" button or unlock the front door with the key to get it out of theft mode.

If the engine does not start or run at all, start by checking for spark and fuel pressure. If you have spark but no fuel pressure, suspect the fuel pump. If you have no spark, chances are the fuel pump won't be running either but that can be misleading because it will still run for one second each time you turn on the ignition switch. That will result in enough fuel pressure to make it look like the pump is running. If there is no spark there may be a related diagnostic fault code. I can describe how to read them yourself, but only codes in the Engine Computer.
