Ground issues

[moondog]

I have changed my injectors and fixed my fuel line quick disconnects thanks to the menbers here :banana: Now my fuel gauge and the dash lights on the far left side went out when I hit a bump. they came back on briefly and now the gauge shows empty and the gauge lights on that side don't work. I think it's a ground issue but I don't know where to start looking. any help is welcome. 1988 4.0
