Hello, I have a 2007 Honda Accord and I replaced my original fuel pump with an off market new Walbro 255. However, my car delays when I attempt to start it and sputters when I accelerate. Also a lot of fuel comes up through the line. I assume that my spark plugs are the issue so I’m looking for assistance from anyone who knows which spark plugs I can use to solve my problem or to cut down the excessive amount of fuel that comes up.
P.S I’m a mechanical engineer which is why I made such assumption.
