Lady brought this in, won't start. Says she may have run it hot and it quit on her going up a hill.

I'm getting these codes:
P0117
P0352
P0193

The starter is spinning and motor is turning but not cranking. I'm sure I have fuel because I smell it. Also I can hear the internals moving but I think the compression may be too low. What are your thoughts?

Good evening,

Start with a compression test to be sure. It will tell you if there is any damage in the motor.

I would also check the wiring for any damage from the engine getting hot.

Removal and Installation

WARNING:
Do not smoke or carry lighted tobacco or open flame of any type when working on or near any fuel-related components. Highly flammable mixtures are always present and may be ignited. Failure to follow these instructions can result in personal injury.
Fuel in the fuel system remains under high pressure even when the engine is not running. Before working on or disconnecting any of the fuel tubes or fuel system components, the fuel system pressure must be relieved. Failure to follow these instructions can result in personal injury.

1. Release the fuel system pressure.
2. Disconnect the battery ground cable.
3. Disconnect the fuel rail pressure and temperature sensor electrical connector and vacuum tube.
4. Remove the 2 bolts and the fuel rail pressure and temperature sensor.
To install, tighten to 4 Nm (35 lb-in).
Inspect the O-ring seal and install new as necessary.

5. NOTE: Lubricate the fuel rail pressure and temperature sensor O-ring seal with clean engine oil.

To install, reverse the removal procedure.
