Hey There are some good posts on this forum about the GDI and fuel pressure/pump try searching. Generally it seems like you are having a fuel delivery problem. First try and change the fuel filter, it is located after the fuel pump by the back right side tire. You can get a replacement at Jurawans, Bobbys, Faiz etc. Jurawan and company have a generic for about a 100. Some ppl say not to use it but i know many ppl who have used it and had no problems....New is about 600 from Diamond.
If that does not solve then you need to check the rear (in tank) fuel pump's pressure and the high pressure (on engine) fuel pump. The high pressure value is generally about 4.8- 5.5 MPa depending on the driving condition and the GDI engine. Most ppl use 5.0 as the estimate. You need to carry it by an electrician with a scanner to get those readings. The low pressure is given on the facebook site in this post, i won't quote it because i never remember it but it seems right.
If the high pressure is off then you can adjust the pressure, do a search on this site and you will get the procedure.
