Hi just got the car finally got below freezing and the car won’t start. It was 24 degrees Fahrenheit out when I took the photos. ignition on not running. I don’t know a lot about these cars but I am a somewhat educated mechanic. Just not completely sure what I’m lookin for.

Replace your coolant temp sensor.

K ordered the coolant temp sensor was like 27$. They asked if it was a Mitsubishi motor or Chrysler I said Chrysler but I’m Not sure. how do you tell if there is a difference or if it even matters. If I’m mistaken the 420a was the Chrysler motor but they also asked if it was turbo’d so I don’t know if they got the right one sent.

Right off the bat, if you have an AWD, that means it's a turbo. And if it's a turbo, that means it's got the Japanese 4G63. The coolant temp sensors for those are fairly cheap, but depends on the brand.

The 420A is the Chrysler engine, correct, but that only comes naturally aspirated (without turbo).

Ok I swapped out the sensor and it still don’t start. :/ guess I’ll start with fuel pressure and work froM there.
