- My model of MX-5 is: __NC1
- I’m based near: __Kent
- I’m looking for technical help or recommendations on: __fuel gauge / sender
I have a 2007 model year NC1 2.0 Sport with the following symptoms:
Fill tank - drive 200miles, fuel gauge slowly drops to 50%.
I think wow my new ECU/remap is efficient.
Car runs out of fuel.
Gauge still at 50%
Take battery negative off
Put battery negative on
Fuel gauge now correctly showing empty with warning light on
Refil car - drive it for 4 days watching the mileage , same thing gauge stops a little higher this time at 195miles
Car still has a little fuel so before I run out I do the negative on/off trick again. Fuel gauge now shows empty with light on.
Feels electrical - I have just changed from standard ECU to ME442 and this didn’t happen in the last year I owned the car before this change but I didnt think the fuel gauge / sendor routes through the ecu ?
Suspect bad earth somewhere?
