Other Fuel System Pump problems of the 2015 Kia Motor Soul

My 2015 kia Soul was operating fine until 1-7-2021. At about 45 mph the oil light came on , then the engine light, then a pounding sound and then the engine blew up. I had it towed to myrtle beach kia, the dealership where I bought the car. They submitted the incident to their engineering dept. Which approved a new engine. On 1-18-21 the kia service man called to say that the new engine has been installed but that the car doesn't run right. It needs a new fuel pump at a cost to me of about $900. I talked with the general manager who checked with the service dept. And he said that the warranty only covers the drive train, plus they found no evidence to show that the fuel pump was affected by the engine incident. I paid the $896. 40 for the new fuel pump and picked up the car yesterday. Does this sound right? the car runs fine. . . There's an engine incident which is covered by the warranty or the recall. . . Now I have to pay $900 to get my car back to where it was???.
