Shifo:
Your English is pretty good. I see a lot worse from some Americans on here! Anyway, I don't believe anyone has mentioned yet that the in-tank fuel pump is connected to a very short length of rubber "accordion-like" hose before it reaches the metal line that runs out of the fuel tank. This piece of rubber hose can deteriorate and cause problems such as those you describe.
Good advice from the others regarding checking the ground wire and for voltage in the power wire at the top of the fuel tank. Bad grounds lead to all sorts of problems with the fuel injection systems in these cars (and their sensors).
The test I like to use to check the in-tank pump is to run the fuel tank down to less than 1/4 full, then with the engine off, disconnect the fuel line that comes from the tank at the rear of the main fuel pump (under the car, left side, simple hose clamp). At the fuse panel, connect a jumper wire from the in-tank fuel pump terminal (fuse #4, I believe) to #13, or another terminal that gets power when the key is turned to "on". Aim the fuel line hose into a gasoline-safe container and have an assistant switch the key to "on" but do not start the car. The in-tank pump should come on, and you should get a good strong stream of fuel from the hose. If you don't, but you hear the pump running inside the tank, the accordion hose is bad. If you don't hear anything at all, the in-tank pump itself is bad. There should be some information regarding the replacement procedure for these pumps in the archives. Good luck.
