has that motor been recently swapped in? if so...have you swapped your fuel send and return lines?...you said in your video you ddint know why you didnt have fuel pressure...andn that it cuts off after 12 sec....like you fuel is pressurizing youre fuel rail...then gettin block at you re fuel filter casue its goin the wrong way...your fuel pump is designe to run at a constant volum/pressure which is why you need a return line to keep that fluid moving.....swap thos 2 lines and see what happens...
