Hello, Eddie here and I will do my best to help. Do you happen to have or have access to an OBD II type scanner? I would like to see if any codes are being set. Is the check engine light on by chance when it is running? thanks.

Expert:  Edward replied 6 months ago.
I've looked and I can't find out why this P0455 would make it not run. Let me opt out in case another expert has seen this problem. When I opt out another expert can assist. Thank you.
