Hello Ivana flores.
Sad to hear from We are a garbage place,
But I will try to explain how a internal combustion engine work.
First time and only time we work in u 1999 Volvo problem was a fuel pump.(car came on a tow truck and don’t start condition)
We never try to fix anything else.and u mil light (Check engine light) was on already plus abs light.A fuel pump is a frequently (but not always) essential component on a car or other internal combustion engined device. Many engines (older motorcycle engines in particular) do not require any fuel pump at all, requiring only gravity to feed fuel from the fuel tank or under high pressure to the fuel injection system. Often, carbureted engines use low pressure mechanical pumps that are mounted outside the fuel tank, whereas fuel injected engines often use electric fuel pumps that are mounted inside the fuel tank (and some fuel injected engines have two fuel pumps: one low pressure/high volume supply pump in the tank and one high pressure/low volume pump on or near the engine).[1] Fuel pressure needs to be within certain specifications for the engine to run correctly. If the fuel pressure is too high, the engine will run rough and rich, not combusting all of the fuel being pumped making the engine inefficient and a pollutant. If the pressure is too low, the engine may run lean, misfire, or stall.
And is nothing todo whit u mil light (check engine)
