| you shouldn't have to wait months for an ecu upgrade.. and you don't need to put everything back together and start it (especially with the wrong chip) to find out if an injector is bad, or an o-ring is pinched. install the rails and hookup your fuel system. keep the upper plenum and everything else off. turn the key so the fuel pump turns on but doesn't turn over, check for leaks by looking into the lower plenum. and there's no reason your new nismo's should be faulty.
