If your 1988 Volvo 240 is stalling after running out of fuel, it is important to have the fuel pump checked to make sure it is not damaged. If the fuel pump is damaged, it will need to be replaced.
In addition to the fuel pump, you should also check the fuel filter to make sure it is not clogged. If the fuel filter is clogged, it will restrict the flow of fuel to the engine, which could also cause the engine to stall.
Here are some steps you can take to troubleshoot the problem:
1. Check the fuel level in the tank. If the tank is empty, add fuel and try to start the engine again.
2. If the fuel tank is not empty, check the fuel pressure. The fuel pressure should be between 28 and 35 pounds per square inch (psi). If the fuel pressure is too low, the fuel pump may be damaged.
3. Check the fuel filter. The fuel filter is located in the fuel line near the engine. If the fuel filter is clogged, it will restrict the flow of fuel to the engine.
4. If the fuel pump or fuel filter is damaged, it will need to be replaced.
