2002 Sportage, just replaced the motor, old one still running but had 300K and someone gave me one out of a wreck with only 56K. Driving along and suddenly no power, thought I had run out of gas fuel gauge read 3/4 tank, but hey they can be wrong. Put gas in it and nothing, it'll start but quits almost instantly. If I remove the top vacuum line and spray starter fluid in it will run so I know it's a fuel problem. New fuel pump and filter, tried replacing the fuel pump relay. haven't checked the fuel pressure regulator yet but reaching out to see if anyone else has had this problem.
