Buy a cheap test light/probe and use that at the fuel pump plug to check for power in that circuit.It could also be a relay thats at fault so check that for power in and power out,same test tool.There are not many wires at the pump plug but as long as only one has 12v its not a power supply problem.Does the car run at all?

What is the color of the wire by the ignition for the fuel anable


A 2002 grand prix 3.8 liter has a fuel pump that is controlled by the PCM. The PCM supplies power to the fuel pump relay. That relay energizes and allows current to flow to the fuel pump.

In order to help with your problem it may be better to describe the problem to give a better idea of what information you need.

Just change fuel pump an still won't start.


This will take several tests so when you have time let me know and we will begin. If your advanced enough I will lay out a few tests.
1. When you turn on the key do you actually hear the pump working?
2. Make sure the connection to the new fuel pump is tightly put together and saftey pin is put back in and if still possible to access wiring still test for power to the pump with wire tester or ohm meter in the connection union.
3. If not check all fuses under the hood and inside the car, make sure they are good whth a test light or ohm meter.
4. Have the fuel solenoid checked or basically purchase a new on they are not expensive anyway.
5 have scanner put on the car make sure all the Cam Sensor,,Crank sensor, Throttle Position Sensor etc, we are looking for any item caught in live data or engine light is on.
6. Make sure battery is connected tightly and is fully charged (FULLY CHARGED) a weak battery reaks havoc on an electrical system. I am fully positive doing the 6 stages you will find your problem I assure you, and you can get a cheap 40 dollar OBD scan tool code reader at autozone or where ever you may shop.
After before all this make sure the security has not been triggered during your work with the new pump!! if it has cycle the remote with full lock and unloce 1 with the key cycle it un and lock with remote is first then lock with remote and open with key. should solve this problem for you.
anything else just ask. thanks the fixya team

I have a 03 Hyundai accent I just replaced the fuel pump I have no power to the fuel pump I've checked the fuses and the fuel pump relay it won't start I'm not sure what to do next


Do you have a test light? If not, go buy a cheap $5 test light-one with a lead to clip to a ground, and with a needle type probe.
Pull the fuel pump relay out of the terminals it is plugged into-you need to check if the power feed for the pump is still available at the relay. Clip the test light lead to a ground and touch the test probe to the positive battery post-to check that your ground is good- tester should light up. Now touch the probe to all of the terminals that the relay plugs into. One terminal should have power with key off. If no terminals have power, you have lost the power feed for the pump. Double check all your maxi fuses in the power distribution box. Either a maxi fuse or a fusible link will be the power feed for the fuel pump relay.
If the power feed is there at the relay, try a new relay. If still no pump, a shop will probably have to check your fuel pump circuit.
Did you check for power at the fuel tank while the key was held in crank? When the engine is cranking, the fuel pump wire should have power. When the key is turned to on, the fuel pump should have power for about 2 seconds, to pressurize the fuel system. Then when key is turned to crank or start, the fuel pump should stay on.

Need color code on new connector


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.
