Car always stalls regardless of fuel amount

Welcome to 2CarPros.

If you are running it very low, it could be picking up dirt from the bottom of the tank. Have you ever replaced the fuel filter? Have you ever checked fuel pressure? If you haven't, that is where I would start unless it starts running normally after a bit. Also, let me know if the fuel gauge eventually begins working.

Here is a link that shows how in general to check fuel pump pressure:

Here are directions for testing fuel pressure specific to your vehicle. You can do this without a scanner but the directions include one. Also, the attached pictures correlate with the directions and the manufacturer's specs are included in the directions.

ON-VEHICLE INSPECTION

1. CHECK FOR FUEL PUMP OPERATION AND FUEL LEAK

pic 1

a. Connect the hand-held tester to the DLC3.
b. Turn the ignition switch on (IG).

NOTE: Do not start the engine.

c. Turn the hand-held tester on.
d. On the hand-held tester, select following the items: Powertrain / Engine and ETC / Active Test / Control the Fuel Pump / speed.
e. Check fuel pump operation while operating it with the hand-held tester.
f. Check that there is pressure in the fuel inlet hose.

If the fuel pump does not operate, replace it.

g. Check that there are no fuel leaks from any part of the fuel system.
h. Turn the ignition switch off.
i. Disconnect the hand-held tester from the DLC3.

2. CHECK FUEL PRESSURE
a. Discharge fuel system pressure.
b. Using a voltmeter, measure the battery voltage.

Standard: 11 to 14 V

c. Disconnect the negative (-) battery cable.
d. Disconnect the fuel hose from the fuel main tube.

e. Install SST (pressure gauge) using SST and a fuel tube connector as shown in the illustration.

SST 09268- 41048 (90467- 13001, 95336- 08070, 09268-41500), 09268-45014 (09268-41200, 09268-41220, 09268-41250, 90467-13001)

f. Wipe up any gasoline.
g. Connect the negative (-) battery cable.

h. Connect the hand-held tester to the DLC3.
i. Start the engine.
j. Measure the fuel pressure at idle.

Fuel pressure:
304 to 343 kPa (3.1 to 3.5 kgf.sq.cm, 44.1 to 49.7 psi)

- If the fuel pressure is greater than the standard value, replace the fuel pump.
- If the fuel pressure is less than the standard value, check the connection of the fuel hose and the fuel pump.

k. Stop the engine.
l. Check that the fuel pressure remains as specified for 5 minutes after the engine stops.

Fuel pressure:
147 kPa (1.5 kgf.sq.cm, 21 psi) or more

If the fuel pressure is not as specified, check the fuel pump or fuel injector.

m. After checking the fuel pressure, carefully disconnect the negative (-) battery cable, and remove the SST and fuel tube connector to prevent gasoline from splashing.
n. Reconnect the fuel tube to the main fuel tube.
o. Check for fuel leaks.

If you find the pressure is low, I would first replace the fuel filter to see if that changes things. Here is a link that shows in general how to replace a fuel filter.

__________________________________________

Here are the directions specific to your vehicle for fuel filter replacement. Now, you will need to remove the fuel pump on this vehicle to access the pump. However, there is an access port to the pump so you will not need to drop the tank. While you have the pump out, check and make sure the float leveler is free and not stuck on anything. All of the remaining pics correlate with these directions. Also, these directions are for fuel pump replacement, but you need to remove the pump to access the filter, so it is relevant.

I have a feeling the filter is the problem. Let me know if you have questions or need help.

Take care,
