I am working on a 2010 frontier I havent had alot of time to run diagnostics yet I am gonna do it wed. I did check all the fuses all are good thier is no codes related to engine when i check the bcm thier was a c1735 i didnt have to time to run that down yet but I'm not convinced its the switch it turns over but wont start i sprayed it with starting fluid still no start i havent check spark yet im guessing it has none they did tell me that it did this before but it started after sitting for a bit but now it wont start at all if someone could point me in the right direction i would appreciate it thank you.
