[QUOTE="jarance, post: 111504, member: 21"] you have a almost broken wire in the fuel guage. Hence it will come in intermittenly. For an e36, there are two fuel level sensors. I am not about yours. If one of the wires is broken, the fuel guage will shows empty because both of the fuel level sensore are wired in series. Most of the problem of the loose wire is cause by the wire becoming loose when the stopper or damper for the fuel pump become brittle and break. This will caused the fuel pump to become "lowered" and start to pull the fuel sensor cable and cause it to become loose from it terminal whenever your car goes over a bump. To rectify, check the resistance of each fuel sensor. the resistance should be about 10 to 150 ohms depending on the amount of fuel in the tank. if you have two fuel sensors, the resistance should be about the same for each sensor. Note. The fuel sensors are located under the rear seat. When you found or determine the faulty sensor, you can dismantle or remove the fuel sensor. check for loose wire by trying to pull the wires. or if you have an ohmmeter, check the resistance from the fuel sensor to the terminal. You can replaced the faulty wire by cutting the affect wire and reconnect with a slightly longer wire by soldering. ps.. make sure that you use wire that have insulation sheath that is resistance to petrol.
