After some unusual readings (indicated fuel level too low) the gauge sits down at zero now, reporting low fuel alarm each time I start the engine.
I wonder what will happen if I continue to drive - will fuel management system stop the engine after certain number of kilometres to prevent total out of fuel? Janusz www.yahodeville.com |

Eventually the ECU will start to make the engine misfire, then it will cut out and only allow you to drive a mile at a time to protect itself.

The solution is to fix the sender |

I have an early Puma I guess. 115 km on 'empty' and still going on without misfire.

1. check wiring only two wires with multimeter may open cct
2. fuel sender may be open cct Click image to enlarge |

Thank you! I was just looking at the same diagrams.
As far as I understand, the fuel level sensor is resistor type. Do you know the min-max values of the resistor? If known, I can plug proper resistor into the connector at the tank and see what the gauge shows. Or there are easier ways to check it? Janusz www.yahodeville.com |

As the follow up to the story. I have removed suspected gauge and investigated the sensor. It is encoder, not resistance type, so will not show any resistance (open / infinity). See the pictures.
