No power to fuel pump relay on solenoid side. (small wire) My diagram shows it coming from a 20a fuse. All my fuses check OK under the dash and in the underhood fuse center. Where should the power come from?

Might be a break in the wire check to see if the wire is still good

On a 2005 hyundai sonata I have a no start condition. Fuel pump works fine but getting no power to it. Fuel pump fuse is good. 2 things I can't find. A fuel pump relay and a fuel pump reset switch?


If you have a four cylinder, the fuel pump doesn't have a separate relay, but rather its relay is built into the ECM relay. This relay is behind the center portion of the dash bolted onto the right side support bracket there. It's powered by one of the 30A slow blow ignition fuses in the underhood fuse block.

If you have the V6, there will be two separate relays on the above referenced bracket. The fuel pump relay should be the lower one of the two. For this relay, power originates at the 20A fuel pump fuse in the underhood fuse block.

Hyundai's online schematics are an excellent tool for this task. Simply register for an account at www.hmaservice.com. When inside, go to the ETM (Electrical Troubleshooting Manual) link in service information, select your year and model and MFI fuel system. The first page will show you the relay and additional information. If you click on the connector number for a component, it will bring up a separate window, in which you can click on links at the top to show a diagram of the connector, a picture of the component/connector, and a diagram of the wire harness in the vicinity of the connector.

Hope you can read it, the load side of relay gets voltage from fusible link. The load side of relay is that line with arrowhead, showing open switch on left side of relay in diagram.

No power to fuel pump or to pump fuse at fuse block


You can get wiring diagrams from autozone.com -- they have parts of repair manuals online. I have the smae problem but the person I got my 88 fox gl from wired up a switch going to the fuel pump that you have to leave on while driving. I"m probably giong to fix this soon. It looks like the wire powering the fuel pump relay comes from the ignition switch. So if the pump side of the relay is good, but aren't getting power, you may want to see if your ignition switch isn't providing power on one wire, going to the fuel pump relay.
