Hyundai Accent Crdi 2010 problem

Hi, I'm new, my car stops to bend to the right, take it to the scanner threw injector (they told me that it was impossible because it only stopped by bending right) took it to the consequence and repaired it said it was a cable that came out from the fuse box and if I followed the prob. It could be the oil pump or a hard injector for a month without any problem. And now the car stops or boards with low revolution pulls, stop treading in accelerator and continues. Please if someone can help me since I meet these two problems
