If the car has been run completely out of fuel, this may suggest the fuel may have possibly been burned up. The fuel pump relies on the fuel in the tank to keep it cool and lubricated. When the tank is run completely dry, this will cause the pump to generate an immense amount of heat and in some cases cause it to burn up. If this is the case, this may cause the car not to start due to a lack of proper fuel pressure. I would recommend having a professional from YourMechanic come to your location to diagnose and replace your fuel pump.

What Happens to a Car When You Run Out of Fuel? When the tank`s left to run completely empty, the engine will start to draw in air along with the last dregs of fuel. This air could stop the engine from starting again, as it throws the fuel-air mix needed for combustion way off kilter.
The gas in the tank will not only power the vehicle, but it also serves a few other functions, like cooling and lubricating the pump. Regularly running a vehicle out of gas will cause the fuel pump to overheat and eventually fail.
The most common reasons a Honda Accord won`t start are a dead battery, an alternator problem, or failed starter. Search our network of RepairPal Certified shops near you to speak with a technician about your issue.
The fuel injectors may clog.
Your fuel filter is responsible for filtering out all that bad stuff so that it doesn`t make its way into the engine. But when your fuel level gets too low, those impurities can get pushed through your fuel lines and clog the fuel injectors, the tiny nozzles that spray gas into your engine.
Prime the fuel system by turning the ignition on (Run position) for 30 seconds, but do not start the engine. This allows the pump to prime the system. Turn the ignition off, and then crank it for 15 seconds. If it does not start, repeat the first task and this one until it starts (cycle the key).
When you run out of gas, the fuel pump will still activate and try pumping but it won`t be nearly as loud because it will just be spinning in instead of trying to push fuel so it will be such quieter.
If you do run out of gas, your engine will sputter and stall as it gets starved of fuel. In this case, your catalytic converter, which is part of your vehicle`s exhaust system, can get damaged and you may need to repair or replace it.
Once your car runs out of gas, your car will shut down as if the key was never in the ignition. This is dangerous because by this point if you haven`t been able to pull over to a safe spot, your car will stall exactly where it is.
Why won`t my car start but the battery is good? If your car won`t start but the battery is good, the most common cause is a faulty starter – though it could also be to do with your fuel. You may have insufficient fuel to get the car going.
The most common reasons a Honda Accord key won`t turn are a binding steering column/lock, an ignition switch issue, or a problem with the ignition key.
Debris blocking the suction strainer or foot valve is the most common cause. A blockage in the intake line can cause the water in the pump casing to overheat and literally boil out of the casing causing the pump to lose prime.
Just because you hear the fuel pump run does not mean it is pumping the correct pressure to the injection system. If the pressure is real low or the filter is plugged solid, then the pump may not get enough fuel to the fuel rail. The only way to know is to test the fuel pressure at the fuel rail test port.
Electronic Control Unit (ECU)
The ECU is the brain of the operation. It uses engine RPM and signals from different sensors to meter the fuel. It does this by telling the fuel injectors when and how long to fire. The ECU often controls other functions like the fuel pump and ignition timing.
The fuel tank pressure sensor is part of the fuel pump assembly and is mounted on top of the tank or inside the tank. It`s part of the evaporative emissions system (commonly referred to as “EVAP”) and reads pressure in the fuel system to detect evaporative leaks, such as a loose or faulty gas cap.
The basic operating system for an electric fuel pump is relatively simple. When the key is turned on, the powertrain control module (PCM) closes the fuel pump relay, which activates the fuel pump for about three seconds to pressurize the fuel injectors.
Another key indicator that fuel has gone bad is if the car suffers from operational problems. That could mean failure to start, a hesitant ignition, a rough-sounding idle, or loss of power while driving, especially when accelerating. The state of gasoline can also be determined by its look and smell.
Assuming the same annual rate of U.S. dry natural gas production in 2021 of about 34.52 Tcf, the United States has enough dry natural gas to last about 86 years.
For many it`s the most frustrating, forehead smacking mistake a driver can make, but it`s not exactly rare. In fact, over 800,000 people per year end up empty or close enough to stop driving.
The battery can be fully charged but still not be able to start the vehicle if it is failing or has a dead cell. Other likely issues are the fuel pump, ignition switch, battery cables, starter, or a clogged fuel filter.
In fact, most sensors are responsible for actually making the changes to critical systems such as ignition and fuel systems. Since any engine requires the correct air to fuel ratio and ignition timing to start, having a faulty sensor that can`t adjust these symptoms on the fly can cause the engine to not start.
A Bad Crankshaft Position Sensor
The crankshaft position sensor monitors the position and rotational speeds of the crankshaft. Without the crank sensor, the engine control module (ECM) wouldn`t know when to fire the fuel injectors and ignite the spark plugs.
Normally, just running out of gas will have no effect on the battery unless the battery is very weak to begin with. If it is weak to begin with, the extra running time for the fuel pump to get fuel up to the engine MIGHT be enough to draw the battery down enough it would fail to start the car.
