The check engine light is on. Have replaced fuel pump & filter. Tried jumping TE1 & E1 at diagnostic port but it will not flash any codes? pulled plugs seems to be running on lean side by plug reading. Tried clamping off fuel return line to make sure pressure regulator was not stuck open, no help. Not really wanting to sort to parts replaceing by chance. Anyone know of another location to try and get engine light to read the codes that diagnostic port?
