Engine Mechanical problem
1989 Mitsubishi Lancer 4 cyl Front Wheel Drive Manual

Hi,

Good day!

I'm from the Philippines, I learn lot of things from this website.

I have a problem with my car right now, Car wont start unless I pour a gasoline on a carburetor then stop the engine once the gasoline on a carburetor empty then when I try to start again car wont tart anymore. To start again need to pour again the gasoline on carburetor. Before I encounter the same problem, but after I replace the gasoline filter and pour some gasoline on a carboretor the car start and working perfectly. Now, Its happened again. Can you help me guys what should I do?

Do I need to replace the fuel pump?
How do I know if the fuel pump is really the problem?

I already replace the spark plug and cleaned the distribution cap for possible corrusion.

Thanks in advance and more power to you guys.
