Hello,
I had my fuel tank seemed to be empty, and I tried to start the car 3 times, of course it could not start,
during that time I recognized the problem, and soon brought 5 liters of gasoline and filled the tank, started the vehicle , and as soon as possible filled the tank to about 27 liters of gasoline..
but after that I started to have difficulty starting the vehicle or sometimes she could not start even , I hear the sound of the fuel pump running each time I put the ignition on the on button ..

sometimes I could start it only the second time I run the ignition, even so I still have it difficult to accelerate as when it was normal ...
please if you have any help...
thank you

Hi,

There is a chance the fuel pump was damaged or dirt from the bottom of the fuel tank was picked up and is not restricting fuel flow.

I need you to check the fuel pressure to see if it is within the manufacturer's fuel pressure specifications.

Here is a link that explains how to check the pressure:

You will need a fuel pressure gauge to do this. However, most parts stores will lend one to you for testing.

I attached the manufacturer's fuel pressure specifications below for you. Try this and let me know what you find.
