2001 Toyota Rav 4. Went to pizza wouldn't start. Replaced fuel pump, checked battery, fuses,relays are all good. Replace spark plugs. It ran great driving and it died and couldn't and would not start. There is no power to the fuel pump. Also with the key out of ignition the instrutment lights flicker with the door opened or closed, the shift indicator lights and the oil light just flicker non stop unless unhook battery. What is going on? Anyone else have or had this problem?
