i just replaced my 00 dx hatch with an ex floor harness to do power window conversion and now sometimes my car wont start...the fuel meter goes down and it wont start...its pretty much thinking theres no fuel in the car...but when i move around the wires around the fuse box and get lucky the fuel meter will slowly go up and now im able to start it...is it my grounds or am i suppose to do some wiring since i switched over to an ex floor harness.....
