The fuel pump relay is behind the left side of the dash. I know there are a lot of other relays up there also but that is all my data tells me.

Are some of the gauges working or are they all out? If the fuel and temperature gauge is out then there may be a problem with the regulator in the dash.

...the easiest way i found to get to those relays is to remove the screws which hold the fuse block and the whole thing is one piece your can just slide it down and it comes out....its a b&*%$ trying to identify them correctly with the fuse box still up there....

Fuel pump is the last thing to look at, and subary relays are fairly robust.

You need air fuel and spark for ignition.

Do you have the other two?

Can you explain your thread title a little better, that would help.

A little compression helps to ;^)

A check of that may show some goodness or???

slow down, you are doing many things that do not make sense.

Put back the original ECU. They rarely go bad.



You only test one thing at a time otherwise you will never get it started.

First thing first, check to see if you have voltage at the fuel pump at the back of the car.

No spark, you need to use an analog meter to test for a AC heartbeat at the cam and crank postion sensors, especially the cam. This would keep you from having spark. how are you testing for spark?

Check the engine temp sensor also.

I would also do a compression test.

While the fuses may be good you should check to see if voltage is getting to them also with the ignition on. Some fuses feed to other fuses.

Get yourslef a haynes manual. you can trace back the fuel pump wiring much easier that way.

Good luck im going to bow out of this one.

I think voltage for the fuel pump is supplied through the ignition relay so you might try tapping on it to see if that changes things.

I think it is under the dash near the steering column. I don't have access to my data right now.

so i traced poer to the fuel relay
relay was bad, then followed power to pump
pump was bad, rusted solid,
now i have fuel pressure,
working on the no spark issue
coil is not getting the signal to fire
so im checking the cam/crank sensors in the morning

It appears you are making good progess. I suggest you check the ECU for any trouble codes. I assume power is getting to the ignition at least.

If you are in need of any spare parts I have a wrecked 97 outback sitting at the shop and you can pick what you want. I have the suspension for my wife's car, but the entire ignition and fuel system are still in the car. I'm right here in Richmond, so if you need a part you can come and get it or I can pull it for you. You helped me out in the past, now I can help you.

Call me if you want 804-393-0516

I'll get you a picture this afternoon or tomorrow. She looks rough since the drive train and wheels have been removed. She's up on some logs as I dismantle her, but she's got good doors. and interior. The fuel system is still there and the hood is good.

My name is Mike Johnson and you sold me an engine a few years ago for my wife's loyale. I came out in my lifted GL turbo, tan in color.

If you need any other info just let me know. I also have the MAF and a new radiatro for the outback inside my shed.

Mike
