Just did my fuel pump on the 2001 isuzu rodeo. Well 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.

You will have to ask the dealer about wiring diagram of the new fuel pump. You can also tell me the fuel pump details and I can help you.

2012 old post with these facts a clone pump can be connected. (not OE FIT pumps.)
here are the true facts (out of factory book)
2001 USA ? Rodeo , non sport
who's pump , brand and partnumber.?????

2.2L only, you never said what engine in any posts.

F1 pump conn. wiring
pin color function
1 blu-yel sender for fuel level. PCM ensor Ground. (special)
4 org/grn sender same. ( actual sensor out to fuel level via PCM)
2 blk-org pump 12v power.
3 black, pump ground 0v.

so with your unsaid pump, must wire 1 to 1 with above. or boom.
that it is, 2 of the 4 pins, the 2 that make pump RUN.

Fuel pump wiring for aftermarket GM fuel pumps

When replacing fuel pumps in chevy or gmc trucks and suv's the aftermarket fuel pumps come with new plug and wire connectors. Which requires you to cut off the old pigtail and connect the new pigtail to the vehicles wiring, the reason the manufacturers of the new fuel pumps did this is to fix problems with the old style connector that was on the factory unit.

Where is the fuel pump relay on a 1991 gmc jimmy

Thye fuelpump relay is located to the right of the brake booster. this is for a 1991 gmc jimmy (s-15)

I have enclosed a diagram to help locate the relay.

The most common reason for no fuel pressure on these trucks is not the relay but rather the fuelpump itself. the pump is located inside the fuel tank.

There is also a problem with the wiring to the fuel pump, you will need to locate the top of the tank and then off to side of tank is wiring .
This wiring comes off the top of the tank, you will need to check and there is connector problems..
there is one or two ground wires that come off wiring to top of tank which run to frame, check to make sure the grounds are good. if you end up with a bad pump you will see a notice to rewire a new fuelpump connector. hope this is helpful. good day.3_4_2012_1_29_16_am.gif

I need to replace the fuel pump and the parts house sells it with wiring. Do you have a diagram of how to run the wiring?? It is for a 2000 chevy blazer. Need it asap.

Grey is the power to the fuel pump.
Purple is the power to the fuel level sensor.
One black wire should go to the frame (fuel pump ground).
The other black wire should go to a connector and back to the fuel guage.

I have a 1999 gmc 1500 with fuel module problems there are 2 pumps and i have the other pump. the differance looks like 1 of the plugs on top. i have the plug i would like to make work. they are both 4...

hi, if you bought a new fuel pump assembly you are one of many who had problems with the connectors. so your not alone. the fuel pump manufacturers changed the plug configuration to solve a problem with the existing plug, the plug being replaced is the square plug on the left. the new pump assembly came with the new pigtail and you need to cut off the connector(close to the plug so you have enough wire) and ****-connect the new plug onto the trucks wires. the wires will be color coded to match the old wires, they maybe dirty and oily so you will probably have to clean them to tell the difference. also the pump should come with a diagram to help solve the wire problem.

Fuel pump does not come on. car wont start

Then you must have a wiring problem at the rear tank electrical connector or at the fuel pump.

Fuel Pump & Sender Connector - Description & Operation
The fuel level sensor consists of a float, a wire float arm, and a ceramic resistor card. The position of the float arm indicates the fuel level. The fuel level sensor contains a variable resistor that changes resistance in correspondence with the amount of fuel in the fuel tank. The PCM sends the fuel level information via the Class II circuit to the Instrument Panel (I/P) cluster. This information is used for the I/P fuel gage and the low fuel warning indicator, if applicable. The PCM also monitors the fuel level input for various diagnostics.

CAUTION Fuel Vapors can collect while servicing fuel system parts in enclosed areas such as a trunk. To reduce the risk of fire and increased exposure to vapors: - Use forced air ventilation such as a fan set outside of the trunk. - Plug or cap any fuel system openings in order to reduce fuel vapor formation. - Clean up any spilled fuel immediately. - Avoid sparks and any source of ignition. - Use signs to alert others in the work area that fuel system work is in process.
Removal & Installation

  1. Remove the fuel sender assembly.
  2. Disconnect the fuel pump electrical connector.
  3. Remove the fuel level sensor electrical connector retaining clip.
  4. Disconnect the fuel level sensor electrical connector from under the fuel sender cover.
  5. Remove the fuel level sensor retaining clip.
  6. Squeeze the locking tangs and remove the fuel level sensor.

    Fig. The fuel sender assembly consists of the following major components: fuel tank pressure sensor (1); fuel line fittings (2); fuel tank fuel pump module (3); fuel strainer (4); fuel level sensor (5)
To install:
  1. Install the fuel level sensor.
  2. Install the fuel level sensor retaining clip.
  3. Connect the fuel level sensor electrical connector.
  4. Install the fuel level sensor electrical connector retaining clip.
  5. Connect the fuel pump electrical connector.
  6. Install the fuel sender assembly.

its possible that you need check the next wiring diagrams:


Fig. Engine and Fuel Tank Sensors(c) (2000)


Fig. Fuel Injectors(c) (2000)


Fig. Fuel Pump and Relay(c) (2000)

There are two ways to do this; One: you can find the wire that is behind the brake booster or around the fender on the drivers side near the back. It will be a red wire that has an end on it that looks like a plug, but its not plugged to anything. This is what this wire is for, so you will need to hook 12 volts to it, and you will hear the fuel pump come on. Allow it to run for about 10-15 seconds, and unhook it. The engine should now start & run fine. Second: you can purchase a spray can of carb/choke cleaner at a parts store, remove the air cleaner hose going to the intake/throttle body. Hold the throttle wide open, and spray about 4-5 seconds directly into the throttle body. Move the can back, and start the engine. It will run for a few seconds, and stall again. Repeat this until it runs on its own.

Hope help with this.
