第一天，跑完1个半小时高速后，油表指针始终指示在中间位置上，当时还纳闷怎么这
箱油这么禁得起跑，但只是一闪念没想油表坏了，导致第二天早上汽车无法启动，显示
汽车无油。叫了AAA，给加了5块钱油，能启动了，油表指针向上爬了一点点略微超过中
间线。之后，开到油站加油，但是只能加22块钱的油，油泵就自己蹦起来了，不能再往
里面加了，但实际上22块钱的油根本不可能加满油箱，油表指针从中间点直接爬到了最
顶端（表示油箱全满状态）。有事，无法直接开去garage修理。
第二天，继续有事。
今天，再次无法启动，指示无油，油表指针在满格状态。叫了AAA，但是要至少1-2小时
才能到。
这有可能是什么问题？拖去修大概多少钱？自己能修否？

1. Locate the fuel tank of your car. There should be a wire near the tank
with a tan color – this is the “fuel sender feed wire”, which indicates
to the fuel gauge how much gas you have left in the tank of your car.
Disconnect the wire at the base to test it.
2. When the wire is disconnected and the node hangs loosely in air, the
needle of the fuel gauge should be reading above full. If the node is
touching the ground (with no flow of electricity), the fuel gauge should be
reading below empty. If these are not the case, you have either a wiring
problem or a defective fuel gauge.
3. Find a multimeter. A multimeter is a device that measures the electrical
current that flows between two points – it shows you the amount of
electricity at your disposal. Using the two points (the metal needles) of
the multimeter, connect one end to the wire (the tan wire – fuel sender
feed wire) and the other end to the ground (a surface with no flow of
electricity).
4. Differing amounts of electrical flows indicate the amount of fuel in the
tank, with a higher number of power (measured in ohms) indicating a fuller
tank. If the multimeter does not measure any output, recheck the wiring to
see if it is connected to the tank or that the wire is grounded.
5. If it still doesn’t work, chances are that you have faulty wiring. To
check for this, disconnect the tan wire involved with the connection between
the gauge, and check it (run a finger along to wire) to see if there is any
wear and tear along the wire. Replace the wires and make sure that
everything is connected and grounded properly to check it if works.
6. If it still doesn’t work, try replacing the tan wire. If you aren’t
sure which wire would work for your car, consult the nearest dealership to
get a professional opinion. At worst, when even replacing the wire doesn’t
work, you may also need to replace the fuel gauge.
