Can you see the fuel injector/s spray pattern, does it look ok? I have seen spray patterns that looked good to me, but, the fuel pressure was half of what it should have been. For TBI 9--13 psi. Did you try adding a little gas to throttle body, to see if it came closer to starting, like a small cap full? Any applicable trouble codes? I would want to see if vehicle is running rich or lean. Could be other issues.
