definitely thinking fuel pump now. the reading is always zero. got plenty of pressure. exhaust smells of gas , bad misfire at idle and long term fuel trims near -20 at idle. plugs are clean but I'm thinking that it's so rich that its washing them clean. also, bad MPG. it must think that the pressure really is 0 and is trying to compensate and can't compensate enough.
anyone else want to weigh in?
