Sorry to resurrect this thread. So just bought my M35 VQ35 Stagea recently and wanted thoughts as to whether the sender is the issue or the gauge.
Bought car and at the time, fuel gauage read 1/2 tank and didn't move much from 1/2 tank after about 100kms of driving
Parked the car for couple of hours, came back and car was hard to start but i didn't think much of it when it did start.
Car then reads 1/4 tank. Drove for about 6kms and car died. Ran to the closest servo and filled up with 5L jerry can, car now reads 1/2 tank again and looking at the estimate kms to empty it reads 188kms!!
Filled it up again at servo and filled up another 73litres and car now is reading full...
Hard to work it out I guess but thoughts?
