I need to know if the pump is getting power but all of the diagrams I have found do not tell me what color wire is power for the fuel pump.
Expert:  Pete replied 1 month ago.

You have a white wire that sends power to the pump directly from the relay.The green wire at the pump is the pump ground which grounds to a metal body point to provide constant ground.

There is a plug that has 5 wires running to it. None are white. There is a blue wire that is hot the rest are not. There are no white wires. It's a 2007 optima lx 4 cylinder. I need to know how to check if there is power getting to the pump. Checked relay, and fuses.

Just to be sure this is a 2007 Kia Optima with the 2.4 liter am I correct?

Customer: replied 1 month ago.

Expert:  Pete replied 1 month ago.

Where is this plug your finding these wire colors at?

Customer: replied 1 month ago.
On top of the fuel pump.
Expert:  Pete replied 1 month ago.

Unfortunately all my info shows is a white wire leading all the way from the relay to the pump itself.My info isnt matching your models info here.

I will open your question up for others here to see if someone else can assist further on this as there may be others here that may have more info on what to check or do with this issue.I hope you can get this resolved with ease.No need to reply to my last post here unless it is a last resort as it will keep your question locked to me and others will not be able to view it.If you feel you want to continue to work with me on this feel free to reply at any time but keep in mind in some cases it can be difficult to fully diagnose or help repair this without seeing your vehicle.

Thanks Pete
