Other Fuel System Pump problems of the 2012 Kia Motor Sportage

Hi I came home on lunch one afternoon the car drove perfectly fine no issues what's so ever. About an hour passed and it was time to go back to work so I put the key in the ignition and they car never started again. It sounded to me like it wasn't getting any fuel so I thought I'll change the fuel pump. . That's when I learned that there was a fuel pump from a polaris artticat snowmobile that was used by the manufacturer which ok I thought was funny at the time but finding a replacement part was a nightmare. . I finally found a replacement part which I just had to get a whole new fuel pump and assembly but when it didn't start after that I didn't know what to do. I took it to vip and had them take a look they called me back the next day and said they had no clue what was wrong with it and that I needed to come grab it and bring it to the dealer where I bought it from. That's when I learned the engine somehow stopped getting compression and that blew up merchants said I needed a new engine that's $7,000 and when I went to find one that's when I found out it's discontinued gee wonder why so then I go to kia and tell them now I found out there's all these recalls out on kia Sportages but my VIN# doesn't match now how does that work so now I'm out a car and $7,000 and still paying on a car I don't have any more. So how am I to fix a discontinued motor and a polaris artic cat snowmobile fuel pump. By the way I've had the car less than 2 years and only put 30,000 miles on it ridiculous.
