When it is a fuel issue, most of the time it has to do with fuel pressure. Make sure the fuel pump runs, primes up and turns off when the key is turned to the run, on position. There may be something wrong with the fuel pressure regulator, may want to change out the pressure regulator. Also make sure the fuel filter has ben changed, it could be plugged up.
