A year, make, model and engine size would help.

Most late model GM cars it will be the grey or larger grey wire that supplies power to the pump and the purple wire that supplies power to the level sensor.

SOURCE: wire diagram and color code for fuel pump 2002 misubisji galant

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?

I don't think its your fuel. Usualy we connected the kill switches to the ignition or power to the spark plugs. Just to make sure you can buy a can or 2 of brake clean thats what is call. you can buy it in autozone cragens or any autostore. When it does that problem that it doesn't want to start. remove the plastic hose that goes to your intake and spray a little while cranking(trying to start) if starts than your on the right track if it has no change you should start looking power for your spark plugs

The wires should be grey, orange and black, purple, and a black wire. The purple goes to purple, grey to gray. The orange and black goes to the small black wire on your car harness and the black goes to the bigger black.

My Ford Windstar fuel pump work, relay, and fuse work also but there is no power on my fuel pump, any ideas?

Have you checked your fuel shut off valve. It is behind the taillight on the passenger side, open the door where the jack is and look toward the back of the taillight. Should be a black box with a red button on top, if its tripped then all you have to do is push it down you will hear it click and the button will stay down. I try to locate you a wiring diagram. Good luck

Check colors of wires coming off the fuel pump relay, they should correspond to colors of the fuel pump.

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.

What wire is the power for the fuel pump at the pump

there were some production changes in 1998 to the fuel pump wiring, so the connector can have 2 diff fuel pump power wire colors, the most common color is grey, but the the harness at the tank has just 4 wires, the larger wires at the four wire oval connector are the fuel pump 12 Volt and the other is the ground, it is black, the other 2 wires are the sending unit, also the connectors ( Chevy factory service bulletin) on this year had a problem with burning, so if you get a new fuel pump always replace the 4 wire fuel pump connector. I have attreached a picture of the connector
