Not sure where to post this since there isn;t a "General Problems" type forum (yet)

Has anyone else had this problem. All of a sudden 2 days ago My gas guage reads very weird. Full is still full but when the tank is empty the gauge reads exactly half full. It's not like the gauge goes down to 1/2 full and then stops working. The gauge is acting as if the 1/2 full mark is the empty marker. The gauge goes down half as fast as it should so when I have 1/4 tank the gauge shows 3/4. weird huh??? Anyone else have this problem. I guess i need to take it in for Warranty. That will be REALLY fun. Can;t wait to see what they say. Thanks

yeah take it in. there's nothing i can think of that could make it do anything like that because it still has precision (not just readin what it thinks would be cool)

mine tends to hang in the mid range and then drop like a god damn rock!!! it's prolly just a sending unit, not sure how friendly they'll be though since you've pulled the fuel pump...i thought you were going to say you were getting redicilous gas mileage and in that case i was going to be a pest and tell you to stay off the boost and nitrous but then again what fun would an EJ22TN be w/o the TN??

hehe. True.

Bad story: I My family was in town all week in three different hotels for my graduation so I totally lost track of how many miles I drove. On my way home from graduation, I noticed my Fuel pressure gauge was jumping around and was idling at about 25psi. I couldn;t figure out what was wrong so When I got home I opened up the hood and everything looked ok. I Went to leave later that day and got about a mile down the road when My car went into limp home mode or something (Flashing CE light) and wouldn;t accelerate at all. I pulled over and was under the hood for about 30 minutes taking things apart and trying to figure out what the hell was wrong. I finally pulled the dipstick after trying to start it (unsuccessfully) and there were bubbles on the dipstick. I was like OMFG!!! I blew a head gasket but I couldn;t figure out how that would affect my car the way it dead. I then re-pulled the dipstick a couple minuted later and it looked fine so I dodged a bullet.

After trying everything possible to figure out what could be wrong, I said to myself "I have to be out of gas! There's nothing else it could possible be." I called my mom, had her bring me a gallon of gas and the damn thing started right up. So now I am relying on my trip meter to know when to fill up. At least now I know I am average almost exacly 21mpg (mostly highway. ouch)

wow that hurts...how much time do you spend in boost?? i mean DAMN i get 20 with city driving and 30-33 on the highway...that's super bad mileage.

Don't feel bad... I used to get 17mpg during city driving when I just had the intake on my RS. When I had the turbo on, I was always sorta lean, so I got around 20mpg around town.

Best I've ever done on the highway was 29mpg with my old intake on. Haven't measured with the turbo or recently (stock).

I'm sure it will get much better once I get my fuel pressure under control. I'm idling at almost 50psi right now...

My empty light came on the other day when the needle was sitting at around 1/2 tank. Weird!

OK guys.......here's the story. On Thanksgiving my car started bucking and hesitating. My fuel gauge read half a tank. I had just install my turbo and was freaking out! My fuel pressure gauge was all over the place. Then finally my Ru stalled and would not start again. I didn't have but 10psi fuel pressure, so I thought my new hi flow fuel pump crapped out on me. So my brother-in-law and I pushed my poor Ru all the way home, and I started to pull my pump out so I could put the stock one back in. I pulled the unit out of the tank and looked in. It was bone dry. And then I relized that when I was pulling it out I had to lower the fuel level sensor arm cause it was stuck all the way up. The tank read half full cause Subaru uses two fuel level sensors, one in either side of the tank. It take an average of the two signals. The right side was all the way down, and the left side was all the way up. It hasn't happened again since then, but I alway reset my tripometer every time I get gas to be sure.

whoa james that sucks!! damn 2 level senders...bet it uses a series resistance total to keep em reading right....that's crazy stuff.

So did you bring to to a Dealership to warranty it? What did you do. that must be my problem.

No. I haven't had anymore problems with it. I think when I installed the hi flow pump I tweeked the level sensor arm, and that's why it stuck. I think it's gonna be fine.

 

[Imprezinator]

OK. I'll try to fix my level sensor. That's probably it. It was a pain in the ass to get in and out so I won;t doubt that I tweaked it.

just did a fuel level sender on a new civic the other day and the damn fuel pump assembly is actually SPRING loaded to be held against the bottom of the tank and it's is the shape of an L...i'm suprised i didn't break the old one off trying to figure out HOW in the the hell to get it outta there...good luck eric let us know the results.

You need to come work for Chrysler dude, they're all like that!

 

[LVSUBARU]

They're all like that at Benz also...... But you know: Chrysler...... Mercedes, they're both the same now!:happynow:
