Hello and welcome to just answer, my name is ***** ***** master tech here to help. I cannot see or hear your vehicle so I rely on your input to my questions so I can help you better. I read your question and ready to answer. No the Evap or any evap codes will not make the vehicle not start as it is a separate system , the only thing you may experience is a rough idle under some conditions,Check the rubber vacuum hose to the purge valve fo leaks. Is there anything else I can help you with?

Customer: replied 8 months ago.
maybe I worded my questions wrong as you did not even touch on all the other issues like what is ecp light, where are all these things located, what are the other codes , are they easily replaced
Expert:  Peter Bagley replied 8 months ago.

Ok that code P0441 is for incorrect purge, and yes those are correct possibilities to it's cause and this is why you need to have a shop scanner run an active test on it to check all aspects of that system to isolate the problem. Also with that scanner you will be able to activate each vsv to actually see the area at fault.
