Rodeo fuel pump rewire

Usually on these it is the fuel pump sending unit. But here is how the wires connect. Here is what you need to do about the different wire colors. First disconnect your negative battery. Drop the fuel tank and replace pump. Remember to have a splice kit in hand. Ok now here is how you connect the different colored wires. Black goes with black. Gray goes with black and orange wire. Purple goes wit blue and yellow. And the last wires goes together. I hope this helps.

Fuel pump wire color

The gray wire goes from the pump relay to the pump. The black white wire is the ground for the pump. The purple is for the gauge on the dash and the black is ground for the sending unit. I don't list a white wire being used.
If the colors on the truck don't match the tank, you'll have to test them to verify each circuit.

P0463 Fuel Level Sensor Circuit High Input


Do you have the fuel level sender in the tank or do you have it out of the tank. It is muck easier out of the tank and better results are given. If the unit is still in the tank, you can ohm the sending unit. The wire colors to the resistor are light blue(pin 6) and gray (pin 1)

The only way to test if the sending unit is functioning is to take your ohm reading/add more fuel and see if the reading changes. There are no specs given from GM.

If the code comes back, the sending unit in the tank is no good. The only reason that the code would reset after filling is that the resistor on the sending unit losses connection.
Unfortunatly it is a common GM problem....

Just put a new sending unit in it and all will be well.

Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

Faulty gas gauge

Most of the time its is the sending unit in the fuel tank. The test for it is to use a variable resistor that is hooked up to the wiring at the fuel tank and watch the fuel gauge if the gauge works ok thats makes 100% sure its the sending unit. At 245 ohms the gauge should read full, 180 ohms for 3/4 full, 160 ohms for 1/2 tank, 100 ohms for 1/4 tank and 42 ohms for empty. The color of wires at the fuel tank is purple wire and black wire. You can also use fixed value resisters. If the fuel gauge the wires from the sending unit to computer then to gauge for bad connections, shorts, broken wire and bad grounds. If the wires test ok that only leaves insterrment cluster or computer which even most dealers can't test eather one but the insterment cluster would be a more common problem then the computer. But about 95% of the time it will be the fuel level sensor in the gas tank that causes the problem. Good luck.

What are the color of the wires going to my fuel level sensor at fuel tank

hello, not sure of the colors but if you are having problems with the fuel gauge its most likely the sending unit on the fuel pump. I have owned about six of these Dakotas and every one of them had this problem at one point in time. Best thing to do is get an aftermarket fuel pump and replace the whole thing about $170 for the pump with sending unit . Hope this helps Good luck

Fuel sending unit

Hey nflplayer_7,

Smart move. I've got the schematics and I only see two wires.

The Black wire should be a frame ground.
The Pink Wire goes to the instrument cluster

Get back with me if the colors are different. I'll trace them for you.
