Your question is too broad. Are you having a problem with any particular circuit?

Yes, The fuel gage and fuel pump wires. There are three wires and they are all black. It looks like they could be connected back together nine different ways. I received the vehicle this way. The fuel pump gage works when you click the key to the start position. But when you start the vehicle the gas gage shuts down or quits working.

Your talking about the wiring at the fuel pump connector. The connector terminals letter is in the diagram. The purple wire is voltage for sending unit/fuel level gage. Gray vwire is voltage for the pump. Black wire is ground. If you check voltage on the purple wire use a digital multimeter, the voltage maybe only 5 volts max, a 12 volt test lite may not be the proper tool. That voltage comes from the computer.
