I have a 1984 FJ60 and recently installed a fuel injection system from a 1988 Fj62 into it. everything with the computer seems to be working properly and no codes are showing. We installed a fuel pump (MSD) by the fuel tank and it's pumping out 70psi at the engine bay. The fuel stops at the fuel pressure regulator every time i test it, ive replaced the regulator and it still wont pass it, ive even applied vaccum with a special pump to the regulator and no fuel goes passed the fuel pressure regulator. not all the fuel lines have brass rings on them but i figured this would be ok for the testing part. And the car does have half a tank of gas.
