Just to be clear, it will crank and not start or no cranking at all?
Ok, please give me a moment to type my reply.
This usually indicates a possible issue with the fuel pump. If the fuel pressure is dropping off from the engine, then it will take a few attempts to get it up to the engine and then the car will run fine. This is usually an issue with the one way check valve in the pump module itself.
However, if you can, before you attempt to start it, unplug the mass air flow sensor. Sometimes these will cause the problem and if you unplug it and it fires right up, I would replace that first.Make sure to check your air filter as well. If it's dirty it might not be getting the right fuel mixture to start.Please let me know what more I can do to assist you today.

Yes, that's the one. Sometimes they can cause issues like this without ever setting a code as well.
Thanks I appreciate it. If there isn't any change then it's likely the fuel pump. The only way you can really test it is set it up and get pressure on the gauge, then let it sit overnight and see what the gauge says. It shouldn't drop anymore then about 5 psi
