Does any body knows where is located the fuel pump relay?Because the Hynes book I have it isn't acurate its location;the Hynes book indicates its location under the dash board close to the computer but it is not true.
Does any body has a blue prints more acurate?
My second question is why the two left side injectors are not receiving signal from the computer,right side are ok, since the four sparks plugs are firing right.
Please help. Art.

Cool 90 Legacy info

A friend of mine has a 90 Legacy and is super knowledgable about it - here's his website - he's got a link to email him if it's not under his modifications section already

Well that site would be mine

I'm not sure about the fuel pump relay....my chilton's manual sucks as well. I can probably find out though.

As for the injectors, how do you know the injectors are not recieving signals? Have you tested them, do you have a check engine light?

I would tend to guess they are working properly. Check out my Notes & tips section on my site, I have the procedure on how to pull the ECU codes, to see if you have any problems.

Got any questions, just holler

Hey guys, so I am having a fuel issue myself and suspected it was the relay. If you take off those two screws on your glove it will drop down and you can pull it out. From there, poke your head under the dash, straight up you will see your fuse relay.

--> Legacy777! Great site! I love your sub. I have some pics of my car (Though it isn't running at the moment) that I would love to send you!

The fuel pump relay is under the driver's side dash to the left of the ECU, as close to the fender as you can get.

1 relay will be white (this is the blower motor relay).

The other relay will be green (this is the fuel pump relay).

I just tore both relays off the bracket they were on because they were hard enough to get to as they were. Makes for a little easier access if you go through the little square patch with your left hand and under the dash and behind the ECU with your right hand, and feel your way around.

They are both the same type of relays, and the green relay is for the fuel pump.

Here are some pics to help you out:
Take off the rectangular service cover right here:


The fuel pump relay looks exactly like this one:

This is the blower motor relay which is white, the fuel pump relay will be green.

This is where the fuel pump relay is located:


It is way back there behind the bundle of ECU wires sitting on a bracket. It might be easier for you to break it off the bracket and bring it to the little rectangular service area. At least that is how I got access to my blower motor relay after it crapped out on me.

That is definitely the right relay. However mine (1990 legacy wagon) was under the dash as I described. I guess if you can't find it in one of the spots, go looking in the other! However I would try the glove location first, seeing how your car is the same year as mine and it is much easier to get too.]

So I need some help! I just replaced this relay thinking it got shorted out, but it did not fix my problem. Is there any way to check if my fuel pump went out? I know there are a number of electrical components that are involved with the fuel pump also and I don't want to replace the pump unless I know it's the problem.

Any help you guys have would be great.

You can listen for the fuel pump priming when you switch the ignition to On. Also you can pull the fuel line at the fuel
filter to see if fuel is being pumped.
