The fuel warning light doesn't come on at all

The electronic switch on the top of the fuel filter housing is the fuel filter warning switch.
To reset the warning light on the cluster you need to do this:
1. With the ignition switch off, disconnect the fuel filter warning switch connector.
2. Turn the ignition switch from off to ON.
3. After more than 3 seconds but less than 60 seconds have elapsed, reconnect the connector.
4. After approximately 3 seconds have elapsed with the fuel filter warning switch closed, the
system confirms the deletion of the illumination information by turning off* the warning light.

Since you mention nothing about trouble or warning lights, or about how long this has gone on, I would start with inspecting the air intake (has something been pulled up into it blocking the passage?, is the air filter completely plugged?), and then the fuel system, the fuel pump & filters, expecting the pump to be weak and near complete failure if you find no other valid reason for your vehicle to run this way.

The only other thing that doesn't trigger a warning light that I can think of is the exhaust system from the Catalytic Converter, and components behind it. If the converter is bad, the exhaust pipe behind it will rarely get hot as the converter is plugged.

You can eliminate the fuel pump issue by testing with a pressure tester. A heat sensor or just checking out the exhaust up close without getting burned will tell you if it's the exhaust system.

Beyond that, you'll need to start testing sensors.
Good luck !

1) Try the other fob.
2) Driver door latch mechanism needs repair/replacement.

Hello
If it was a fuse problem none of the gauges would work or the warning lights. The problem is caused by a defective fuel gauge sending unit that is located of course inside the fuel tank. To rpelace this part requires the fuel tank be dropped out of the car.

emmission light.
there is a small vapour leak in the fuel sytem of your car.
this doesn`t mean your leaking liquid gas -only a small amount of fuel vapours.
the emmission system of today`s vehicle are very sensitive, and when the car`s computer monitors this, it will display this information thru your dash warning light.
yor car is still safe to drive, but eventually you will have to fix this problem in order to pass a drive -clean -emmission test. See your service repair shop for further diagnostics..

Yes it does have a low fuel warning light. Mostly when you have 10 liters remaining in your tank.
