i have a 2017 dodge Durango citadel 84k miles
crank no start I've changed
1.keyfob battery
2.aux battery
3.fuel pump
4. fuel sending unit aka aux pump
i don't know what else to try does anyone else no of what it could be or ideas of what i could try or do

 

Find out what is missing. Are you getting spark? Fuel pressure? Injector pulse? Is the Security light in the dash on?

 

spark I'm told yes pressure and pulse is good security light no and any code reader that i connect to it does not show anything

 

When you say code readers do not show anything, do you mean they don't connect, or do you mean they say there are no codes? Have you checked to see if your ASD relay is operating properly?

no codes come up it was one that was for the batter in key fob i changed it but its nothing that comes up as for the ASD i have not im sure the mechanic probably has i will ask him though
