I got my passat b3 as a gift from my grandfather for getting drivers license. A week ago, when I was about to go to the city with my passat which previously was just fine, the engine would not start at all. The following day car was working and I have driven about 50 kilometers. After that day same thing happened: I was trying to start the engine like 5-10 times. One time it would turn on but the engine was coughing and after I pressed on gas it would shut down immediately following with more engine coughing.
I though that it might be something with fuel filter and pump as they were changed 10 years ago. So I changed fuel filter yesterday and tried to turn on the car. However same problem persisted. I could turn on the car in first time but after I presses on gas, engine immediately turned off. Today I changed fuel pump and same thing happened. Engine started in first time following with shut down on gas press. After that I could't start it any more.
I am 100% sure that battery is charged and operating correctly.
VW Passat 1990 1.6 liter gasoline 53kw.
Do you have any ideas what could be wrong?
