1993-2.2-AT-Legacy -HELP?! FPump? Not Alternator, Fuse?


Recommended Posts

Help!

Here's the story.

1993 Legacy.

For a day, anytime between 1000-1500 RPM, the brake light and battery light would come on.

Then, driving home, BANG! Windshield wipers go nuts, car dies. No over heating, no steam, no smoke, (no history of this either)

Walk to NAPA, get replace blown fuse to roll windows up just in time for rainstorm.

Tow car home.

Think: What could it be? (did i mention this story isn't about me but I get roped in?) (Meanwhile, I'm thinking, "Welp, there's the story for my car... guess it's getting loaned out while roommate's car is dead)

Asked around - voted alternator.

Go to AutoZone, get old Alt tested... bad. ok..... cool... replace alternator, charge/ check battery...

Try again:

Key in, Turn key, "RrrrrRrrrrRrrr" "RrrrrRrrrrRrrrrRrrr"

Dang

Call Mechanic brother in next state over

"Dude might be a fuel pump - but check all the fuses first"

Go look for fuel pump fuse / relay

Absolfnknlutley no idea where it is.

Find Fuel Pump door, open it up, turn key to see if we can hear it turn on - nope.

Pull Fuel pump out in well ventilated area.

Before we buy another or whatever....

WHERE IS THE FRIGGIN FUSE/ RELAY or whatever?!

Is there an easier way to test it?

Is there something else this problem could have been?

Help! I want my car back from my roommate.

Thanks

Amanda (aka bluesoob, (oddly, the roommate's legacy is blue)(but not blue anymore - a green outback- how rare! yah one with stickers and a yakima rack on the roof! Really? Never seen that one before.)

So it cranks but won't start. Is the battery charged?

Did you check all the fuses in the underhood fuse panel? There's a Fusible link in there too (looks like a wire with a black shield) that can blow out. It'll be fairly obvious, but if not remove it and tug on both ends. If it stretches and falls apart, it was burned out.

 

The fuel pump only primes for a second or so when the key is turned, and you're not likely to hear it through the filler.

 

Fuse number 16 in the dash fuse panel is for the fuel pump relay, which is under the dash next to large relay with 6 large wires going to it. The ECU grounds the fuel pump relay. It should click once the key is turned to ON, then click again about two seconds later.

The big relay is the main relay and is turned on by the ECU. That should click when the key is turned to ON.
