Fuel Gauge Not Lighting All The Way UP

Yeah, I've been doing the same thing. It's just kind of annoying since I always seem to forget to reset the trip computer.

I tried some Lucas Oil Fuel Treatment two tanks ago. I'm approaching 40k miles, so it was good to add it through the fuel system anyway....but it did not fix the problem. The problem is still the fuel sender and I have the original dealer I bought my car from that is going to replace mine. I still have to work out who's paying for what with Nissan though.

It shouldn't cost you anything from your extended warranty

I got my sender replaced without question and they seemed to know all about the problem. It was all covered under warranty, no questions asked.

Got mine replaced yesterday and the dealer picked up the charges in my case. Not quite sure if it's fixed; when I filled up after leaving the dealer, I still had 1 light not lighting up. Once I got to my buddies house, I restarted it and that last light was then lit up.

Fuel Treatments like Techron Etc.. wont do a thing because the problem is in the Elec Sending Unit itself.
if the light goes on and off, its the first syptom of the problem.

I had the low fuel sender unit replaced last Friday. It does appear to have fixed the problem I was getting at low fuel levels. However, I still have the problem with a full tank not lighting up all the way. I think the other sender unit will also need to be change out.

why didnt they change both of them? being lazy?

I've have been fighting this issue with one particular dealer and Nissan USA for over a month; and neither would acknowledge any problems with the car. Just getting this second dealer to acknowledge, yes...we see the problem just as you do...was a start. In the end, I the consumer, has been ultimately right the entire time. So as long as the second remaining fuel sender gets replaced, then I will be OK. But to answer your question: I presume they were hoping the problem was isolated with one sender unit and the attempt to keep their costs down on the repair work.

Thought I'd come and update after a long while. Mine's a 2010. It's been 4 times since the original post that I've had to take the car back over the last 2years. It will work for a few months then the senders will take a dump again.

This is what happened to mine. They replaced the cluster the first time with no effect, then replaced the senders which fixed the problem temporarily. Like I said about they've failed 3 more times since then 2 years ago.

Um, no. After the third time getting the senders replaced mine started to not light up the top light after a fill up. After parking the car and letting things reset the top light would illuminate so I decided to let it ride. Eventually it failed to the point where after the fuel level reached 3/4 the meter would go totally dead. I'd get the low fuel warning and the 30 miles to empty warning. When it would drain down to 1/4 tank the meter would come back.

I got the car back 2 weeks ago and it's working for now. Nissan was involved this time (I called them)and essentially all they did was warranty another set of sending units and test all the pin outs in the harness. I encourage you to call after the second time you have this issue because it stated in the lemon law if you go to arbitration you've had to make contact with the manufacturer in the 3 attempts to fix it. That way you have the steps in place should you decide to go that route. As you might expect I dont feel really confident it's going to stay working after 3 previous sets of senders. As much as I like the car I may consider persuing them buying it back. Also I've asked them to address the hatch not lifting past the latch when you pop it open either (stuck hatch issue). I think it may be worse on the NISMO because the size of the spoiler. That hasn't been resolved either.

Why?

6MT

Because people should be concerned about the two bottom lights on the guage. Not the top ones. Besides, most people don't fill their tanks up right to the top. So the result is that those lights don't light.

Dead horse thread.

Fair enough.

But I would counter that so long as the problem continues to arise, even in nearly-new Z's, then it's relevant and worth discussing.

Totally agree, there are far bigger problems in life than a flaky fuel gauge. And yes, there is much gnashing of teeth over a fairly trivial problem. But that is, IMHO, the gist of every automotive forum I've ever visited.

However, in my case the gauge actually appeared to get stuck. I drove 100+ miles with all-but-the-last-dot lit. Had it not 'magically' started working again, I could have eventually run out of gas with the gauge reading "Full-1". I was curious if anyone else has experienced this, as that is a bit more concerning than just a 'won't-hit-F' problem.

I wonder if a Miata fuel gauge would solve the problem . . .
