ok so we jus got done doing a s13 SR swap ina 89 240sx. everything is connected and wiring is complete. but when we went 2 start it, it would not start. there is spark, and fuel but there seems 2 be a problem with lack of vacume 2 operate the pressure regulator. so fuel is not being dipursed in the combustion. we took offf the regulator and pluged the fuel line derectly 2 the rail and started it and it start up for a bit when we would fluctuate the vacume by blocking it off. there is really low vacume form the manifold.

anybody got any clue 2 whas going on!!! cuz we don konw. all we know its a vacume issue. PLZ help we have been on this matter 4 2days now. thank you
