You got to get fuel to injectors before worrying about timing. Keep cranking and pumping the manual pump with the lines loose enough at injectors to allow them to leak. Once you start getting fuel out tighten that one down then crank some more to get out of next one, tighten it and, on a healthy engine, should be able to get it to crank with 3 working.

Vac pump is not timed to anything, just the injection pump.
