Hello, my name is ***** ***** I will be happy to help you out. When you say that it wont start after sitting a few days, do you mean that the when you turn the key to the start position it just cranks cranks c4anks cranks cranks but not fires up? Or does nothing hapen like the battery is dead?
You can try the key trick and see if it will display codes. If so, let me know what they are. Another thing that you can do is get the vehicle to an auto parts store. They will connect their scan tool and check the codes for you. Most auto parts stores will do this for free.
Ok, then no codes at least by using that key method. See if you can get a scan tool.
No codes is not necessarily a good thing. No codes could be because the PCM is dead. Just FYI.
