With this year id be concerned abt ignition inputs such as crank sensor, when it wont start see if the car is losing spark
There is no spark once it dies , but it will have spark after 30 mins to an hr

On both the 3.4 and 3.8 its a bypass ignition so during cranking the module alone controls spark without any input from the pcm, all it needs is power/ground and a crank signal.. the cam sensor is a 1x signal thats only there for injector sequencing so it will not give you a no spark
