I have a 2017 Chrysler 300 base model with a 3.5 L V6. The other day we were driving down the freeway and we lost all power to the engine lights ran and radio ran fine. Now the car won't turn over. So far we've replaced the battery, ignition switch, clean ground lead to the engine, replace the camshaft position sensor, and checked every fuse. It tries to turn over but acts like it's not getting fuel but the gas tank pumps hum and pressurized like they should. I don't know what to do next?

 

Sorry meant 2007 300

 

You should get some professional help I think.

 

Have you checked the TIMING BELT? This is also an interference motor and a broken timing belt at road speed will destroy the motor.

 

if the starter does not turn the engine over, and everything esle electrical does, I have to say it's a blown mega fuse in the engine compartment, or a broken wire
