1992 Nissan Maxima 6 cyl Front Wheel Drive Automatic

92 nissan maxima. Changed two injectors seals and o-rings replaced intake gasket (due to hesitation on two cyl.) Replaced intake. Now the injectors are dumping mass amounts of fuel into cyl. So much it stops the engine from cranking. So I pull the spark plugs disconnect the wire on the coil then crank it and the fuel gushes out. Changed the pressure reg. Any clues would help.

Well ECU comes to mind pull connector off injector on 1-3-5 Wht/Grn is power on 2-4-6 white power. The other wire ground put DVOM across key on read voltage? Also key on do injectors click? When intake replaced check to see in a ground wire may have been left off.
