Why does my gas gauge show empty when there is gas in my 1997 Dodge caravan sport?

SOURCE: gas gauge reading empty even when tank is full

Usually if the gas gage does not work yes it is true it may be the sensor if it is electronicly controlled. the sncor will more than likley be in the tank. here is how to remove your gas tank.

1. Before servicing the vehicle, refer to the precautions section.
   
2. Relieve fuel system pressure.
   
3. Drain the fuel tank.
   
4. Remove or disconnect the following:
   
   • Negative battery cable
     
   • Fuel filler and vent hoses
     
   • Fuel tank skid plate
     
   • Fuel tank wiring connectors
     
   • Fuel supply and return lines
     
   • Fuel tank
     
   • Fuel pump assembly
     Fuel pump assembly mounting
     

1. Install or connect the following:
   
   • Fuel pump assembly
     
   • Fuel tank. Tighten the bolts to 27 ft. lbs. (36 Nm).
     
   • Fuel supply and return lines
     
   • Fuel tank wiring connectors
     
   • Fuel tank skid plate

Youre gauge is controlled by a plunger in the fuel tank which is attached to the sensor and the fuel gauge. it sounds like when the plunger goes down half way its either getting stuck down lower then it should. Needs replacing. Any mechanic can do this install for you.

Hi, concerning the left turn signal, this is caused by a faulty or defective flasher relay switch. this is easily replaced and once replaced with a new relay, it will fix this erratic flashing issue you are having. Now, concerning the gas gauge issue. the reason for the non response here is because of a malfunctioning sending unit that is located inside the actual tank. it is part of the fuel pump assembly and it will need to be replaced.

OK, this is concerning the dead radio issue. i would first check the fuse to see if it is ok. if the radio fuse is fine, this will more than likely be an internal circuit issue within the radio itself and, you will have to replace the factory radio. most factory radio systems tend to get really hot and this is not good. it usually ruins the internal circuit board in time, completely rendering the radio useless. i would still make sure the fuse is good. it could be as simple as a blown radio fuse. i will post a step by step guide below that will help you replace the flasher relay.

FLASHER RELAY SWITCH REPLACEMENT GUIDE--

Step1 Locate the fuse box under the dash on the driver's side of the Caravan. Look near the emergency brake. The fuse box cover has two finger screws that you should loosen to remove the cover. Inside you will see a collection of fuses and in the upper right corner a few relays. Step2 Find the turn signal hazard flasher relay in the upper right corner of the fuse box. It should be easy to spot as it is the biggest of the relays in the box. Remove the relay and replace it into the socket from which you just pulled the bad relay. The placement into the socket is tight and can be difficult, but be patient and take your time. Step3 Look to make sure it ended up in the correct position. Close the fuse cover and tighten the finger screws. Start the Caravan and test all the light functions. Make sure that the turn lights blink and that the hazard lights work properly.

Please rate and god bless:)

SOURCE: gas gauge malfunction and engine light stays on

This is a common problem with Malibu's. It is due to cheap metal in the fuel gage that corrodes. Chevrolet knows about this but they refuse to issue a fix. The check engine light staying on and the faulty fuel gage are related. This is a defect and they need to recall this part! Raise hell with the dealership!
