I bashed my fuel tank which which compressed the tank and affected the fuel flow to the pump,and the car refused to start. After working on it, the fuel guage reads abnormal. Any suggesion on how to fix pls?

 

The MAPPS sensor(s) are involved, and not like old style tank floats. See attached from shop manual.

 

Thnks. But does it mean i should change the whole compartment or just the sensors. Everything seems normal, only the abnormal reading. Right nw i have 20liters but the reading is almost full tank. The car is just 4months old with me.

 

You may be able to put the existing sensors back into correct position, or they may have a chunk of trash in them, etc. Just thought you would like an idea of what you are dealing with. The older units were not as complex.
