Doesn't the 350 actually have two sending units because of a "hump" in the gas tank? I'm not sure about the 370.

I believe we have 2 as well.

Which makes having this issue even more pathetic :icon14:

I still maintain it's just a problem with how the data is being output, and the fuel sender's themselves don't have a problem. I guess I could hook up to the OBDII port to verify this, but I don't really care too much. I just enjoy watching you guys suffer. :rofl2:

made me my appointment for monday next week ill see wat they say and wat they do.

The computer buffers the data it receives from the sender and averages over a period of time. You can sit there parked and watch the value creep up slightly with an OBDII monitor. The sender just outputs a voltage, and in some cases I guess that voltage doesn't quite swing the expected full range for one reason or another, whether mechanical or electrical. The CAN bus connection and the computer part seem fine.

I was referring more to the actual display. Do we know at what % (or voltage) the display goes from full to 1 dot unlit and vice versa?

Only the actual sensor uses voltage, once it hits the sender part it is on CAN bus so now it is just a value. The display is also connected directly to CAN bus and is just reading the percentage value given by the sender. I would guess that the display gives a full reading at anything above 95% full. If you want the next time I fill up I'll bring my OBDII reader and see what percentage it shows for me in a working car.

It would be interesting at least. I would agree that about 95% or higher should show up as "full", but maybe it needs to be at > 99% instead. It'd be stupid, but not too surprising.

so just got my car back from the stealership and they change the whole guage cluster and guess wat the last led still dont work so they want me to bring it back in. i told them about how ppl say its the fuel sender but they wanted to change the whole cluster first. well will see wat they say when i bring it in today again. i dont mind its all under warrenty but only thing sux is i gotta get a rental car and pay for insurance so i lose 9 dollars a day

Well obviously they aren't very bright and don't know how to diagnose a problem. In this case all they have to do is fill the tank or have you bring it in completely full, (several gallon change is ideal) and plug the computer into the OBDII port and look at the reported fuel level percentage. If it shows full, it was a bad LED in the gauge cluster, if it shows less than full it is the sender.

Same here, had to pay for a rental car. They had me come in at a quarter tank to change the fuel sender.

A couple of weeks ago I drove my Z out of my garage with 1/3 tank of gas and went out to dinner with my wife and 10 miles later with no warning my car stalled out leaving me at the side of the road. The car was completely out of gas!, no f*cking warning at all! I drove it to my dealership the next day and they ordered a new fuel pump and sender. Your definitly not alone with this issue.

They change my guage cluster twice there now finally changing the fuel sender

Oh crap, you can monitor fuel load with the OBDII port? I want my car back to see

Just got the z today. At first they said next week thursday I was like wtf i drop the car monday but later in the afternoob got my car back. They said they replace the fuel sender both of them and the problem was the thing holding the fuel sender was long and it was getting stuck somewhere so they installed the new sender which is shorter. They said this is a known problem but not much ppl come in to get it fix so thats why there is no recall yet. But they said the recall should come in soon for the senders. Im just glad I got my car back before I leave for iraq. Didnt want to have my brother pick up my car at the dealer dont know where u would take it lol.
