Sometimes not always when I try to start fuel gauge, voltage gauge, and fuel pump will not work. Jeep turns over but will not start. Bypassed fuel relay to start fuel pump comes on still won't fire. If I unplug and replug in wiring harness under steering column it will fire sometimes. Sometimes it takes 40 times. I've cleaned, used wire dryer and WD40 sometimes works. If it starts it does not die. About crazy. Male and female sides of harness looks good.
