Where would this be located? I think it may be the problem. I can’t find it in the fuel rail under the driver side. The only other issues may be fuel pump or fuel pump module, but I was thinking of starting with the cheaper option first. Any ideas what it could be the cause of check engine light? Thank you for helping.
