Get that code.
A failed Crankshaft Positioning Sensor will send no signal to the "brain" which will then NOT start the fuel pump.

You could do a 50/50 test: Get fuel and spray it into the intake whilst cranking the engine over. If it catches (even if it sputters etc.) and dies when you cease adding fuel you know it's fuel related not spark (petrol, I assume).

My '07 has the PEM in the spare tire well. It was flopping around by it's wires. I secured it by gluing it down with silicone rubber sealer. I read that in other years it was atop the tank (basically exposed to the elements) and a royal bear to get to.

I'm not at all sure but I'd look for a FPS on the fuel rail's end.

Plastic tank means there's a fuel filter too....but you say it ran yesterday.
