What are the reasons why a diesel vehicle cannot start after running out of fuel and refueling?

Here are the specific reasons why a diesel vehicle cannot start after running out of fuel and refueling: 1. Electrical circuit failure: The vehicle may have stalled due to a low-voltage power interruption while driving. 2. Electrical component failure: Typically, issues with the ignition coil, capacitor, or electronic ignition module. Symptoms include the vehicle starting initially but stalling shortly after. 3. Fuel system failure: Damaged fuel pump, ruptured fuel line, clogged carburetor fuel inlet, or empty fuel tank. 4. Sensor failure: Faulty throttle position sensor, air flow sensor, intake pressure sensor, crankshaft position sensor, or camshaft position sensor. If any sensor malfunctions, it can cause the engine to stall. 5. Other failures: Engine timing system disorder. Incorrect timing system calibration or engine valve issues.
I remember when driving a diesel car, I also encountered the problem of not being able to start after refueling when out of fuel, which was quite annoying. Most of the time, it's because air got into the fuel line, blocking the fuel like a small bubble stuck in the pipe. The engine can't suck in fuel, so of course, it won't start. My own solution is to bleed the air: find the bleed screw on the fuel pump or filter, loosen it, and pump a few times manually or with the electric starter until the fuel flows out without bubbles. But don't crank the engine too many times in a row, or you might drain the battery. Also, an aging fuel system or leaks can easily let air in. It's best to keep the tank full and not wait until it's empty, and after refueling, check if the filter is dirty and replace it if necessary.
