I move my car to garage few weeks ago, I put off bampers, exhaust system and few little things. When I put back all parts I tried to start my car - nothing! I tried to switch 30 and 87 connectors on fuel relay. I hear fuel pump working, but car didn't start! I just see on front panel sensors of abs, accumulator, brake fluid and they are not turn off, when I turn a key. What it can be?
