My 90GT won't start at ALL. When I turn the key to START my car looses ALL POWER. No cranking, no solinoid clicking, nothing. Even the DOOR AJAR bell stops. I've replaced the battery. Same problem. Even the radio looses it's settings. The dome light, and engine bay lights are REALLY dim all the time. All connections look secure. After reviewing the CHILTONS, I think it's the starter relay. Does this sound resonable? ANY help/suggestions would be appreciated. I don't believe it's the charging system or the starter (no previous problems starting the vehicle) Thanks in advance.
