Ub3rnoob Posted January 9, 2021 Share Posted January 9, 2021 I think I may have a bad fuel pump relay but I cant seem to locate it, It isn't in either of the two fuse panels that I'm aware of, anyone deal with this before? Link to comment Share on other sites More sharing options...

Rampage Posted January 9, 2021 Share Posted January 9, 2021 27 minutes ago, Ub3rnoob said: anyone deal with this before? Yep... It is on the drivers side, under the dash, all the way at the top above all those wiring harnesses almost in the front corner. The fuel pump relay is usually the round body one and snaps into a spring loaded U- shaped clip. You can pry it out of the clip and pull it down a little and unplug it. Not easy to get to. Remove the cover panel under the steering wheel. Put your hand against the outer edge of the firewall and go up as far as you can and feel for the round one. Connector B46 green in the photo of the harness. B47 brown is the main relay. Link to comment Share on other sites More sharing options...
Ub3rnoob Posted January 9, 2021 Author Share Posted January 9, 2021 @Rampage Oh good lord, I'll take another look a little later today, thanks man! btw where did you find that diagram? Link to comment Share on other sites More sharing options...
Rampage Posted January 9, 2021 Share Posted January 9, 2021 You can get single sections of the FSM as pdf files at the following link. Left Click on a folder to open it and Parent Directory to go back. Right Click on a pdf file and Left Click on Save Link As or Save File As. Then select or make a folder to save it in. The Wiring Diagram you want will be the largest file size. The Harness is usually near the end of it. Index of /Auto/Japan (jdmfsm.info) If you go to the following site, you can download the entire FSM in Zip format. Subaru Factory Service Manuals (FSM) - Every Model - USDM/EU (sl-i.net) Click on the one you want in the chart and a new page will open. When you click on the download button (name of the file upper right) on the second page if a new window opens, close it, it is an add. In File Explorer, Right Click on the saved zip file and left click on Extract All. It will extract it to a folder with the same name as the file. BTW, I have file explorer options set to show file name extensions. Makes it easier to identify file types. Link to comment Share on other sites More sharing options...
GeneralDisorder Posted January 9, 2021 Share Posted January 9, 2021 Unless you have no power to the pump when cranking, the relay is not likely your problem. They virtually never fail. GD 1 Link to comment Share on other sites More sharing options...
Rampage Posted January 9, 2021 Share Posted January 9, 2021 (edited) When you remove the panel under the steering wheel, look for two green connectors (test connectors). Plug them in to each other and turn the Key to ON, no start. You should hear the fuel pump cycle on and off along with relays, solenoids and the radiator fans. The cycle will repeat until you turn the key off. If you don't hear the pump run check the connector at the pump for voltage. On that connector there will be two wires that should be hot. The small one is for the fuel gauge. The larger one is for the pump. Don't forget to unplug the test connectors.

moosens Posted January 10, 2021 Share Posted January 10, 2021 Once upon a time not very long ago I chased and chased and got my brother a former Subaru tech involved and after a solid half hour or so found the connector fried out AT THE PUMP. It’s the connector just under the mounting plate as you lift the pump assy out. Hey , it happened to me. Just saying it’s worth it to look at it before spending the chase time I did. Best of luck.

lmdew Posted January 10, 2021 Share Posted January 10, 2021 Load Pro will let you read voltage and Load the circuit at the fuel pump connector. Load Pro: https://www.youtube.com/watch?v=2DwgYI9y2qc Great Tool. You'd have to be all set and have someone turn the key for you as the ECU only cycles the pump for a short time prior to start.

Rampage Posted January 10, 2021 Share Posted January 10, 2021 2 hours ago, moosens said: It’s the connector just under the mounting plate Same thing happened to our 95. My wife called and said she could not hear the fuel pump run. I grabbed another pump and we swapped cars. There was voltage at the plug so I pulled the pump assy. and found the burned connector underneath. I hooked two wires to the pump, brought them out under the rubber gasket and remounted the pump assy. I hooked the two wires to the wires going to the US Mail roof light and drove it home. Then swapped the assy. 1 Link to comment Share on other sites More sharing options...
