Details on your Subaru would help.

Under the fuel rail mount tabs going to the intake. Highlighted below.

I have a bunch of fuel injector rails - Red injecotors, late 90's. Today I pulled 8 for another USMB member. The rails and Injectors were removed from the intake. I removed the Injector cap screws. I tried to push them out. They were stuck. I took a soft wood board, put it on the Injector and clamp against the rail and pulled them together. The Injectors popped right out. The softwood protected the tip of the injector. Nice.

Auto or Manual. Auto's are very heavy, a lift is ideal.

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.

Up high under the driver dash kick panel.

Only thing on the passenger side is the fuel rail and injectors. Nothing to do with filling the tank.

Always nice to remove the half shaft from the hub in the yard to make sure they are not rusted in. It also give you a look at the seals. Not a for sure check but if you turn it an listen closely to the bearing you can get an idea if it's OK or BAD.

You can hook up a multimeter to the connector. It's either OL - Open or 0.0 - Closed for ohms. Yes it does input to the ECU, slight impact on idle RPM. The two connectors are right on the back of the engine as they come up from the trans. Little 2 pin connector. Gray and Brown if my memory is correct. One for Reverse and the other Neutral.

Lots of work, glad you got it. Happy 2021!

1+ Autoparts Store. And get a reader, they are cheap.

A few times I just walked into the dealer Parts Dept with the o-rings so they could match them up.

Hope you had a Great Christmas in this strange 2020. Stay Healthy and Safe as we move into 2021! Happy Boxing Day.

On replacement T-Belts I try to change them out at 80K. Cheap insurance. I've never seen a T-Belt fail. Most often the toothed idler gear goes first.

www.car-part.com Great source!

Check the rear diff and make sure the half shafts are fully seated. I had more than one Subaru where the half shaft uncoupled from the rear diff, but was only about a 1/4" out. Felt like the clutch was slipping in the manual trans.

On my 2000 Impreza OBS the connector was on the passenger side under the plastic trim down by the taillight.

If you can unplug that harness and then see if the short is gone. Nice.

Hope you have a lift. I've done many on my back, its not fun!

No low oil sensor that would impact the start. Sounds more like a fuel delivery problem. Did you hear the pump run when you turned the key on? Might want to check fuel pressure as well. If my memory is correct, your fuel pump has a metal cap on it and sometimes the cap/oring fail. Search the USMB.

Yes, lots of extra work to convert. Get a 95 2.2 the best and drop it in after changing the T-Belt, seals... It will run for years! Lots of info on the swaps here on the USMB.

There is an 05 Outback and well as an 08 Impreza being parted here in COS. They are in the Craiglist USMB tab.

Push Unlock 2x. No way to reprogram that I know of so a single push will unlock all.
