!990 Accord quit on me and troubleshooting fuel pump and main relay. All wiring diagrams from Haynes manual and online drawings show a yellow and black wire at fuel pump and they indicate voltage should be on these two wires. My voltage test is 6 volts to ground on yellow and black as ground or body ground. My pump has a third wire green with red tracer and I have 12 volts to ground. No wiring schmatic shows a green wire at pump. Main relay has 7 numbers but only 6 numbers have terminal, number 4 has no terminal but appears to test correctly
