i have an 83zx NA i bought the car in march and everything was working fine until i took off the intake and exhuast manifold then i installed a MSA header and i bought an intake with no EGR and i also bought a JSK Fuel rail then i put everything back together when i try to start the car it wouldnt start i know i am getting spark and i smell fuel so then i took off my fuel rail on the ON position injectors 1-2-3 does not spray any fuel but on injectors 4-5-6 keeps on sparying so i took 4-5-6 injector plugs and mix it around and it also keeps on sparying fuel on any injectors when i plug it. thank u guys in advance oh yeah i also smell alot of fuel in the oil if that helps..also when i unplug injectors 4-5-6 it it takes forever to start and it also back fires in the intake manifold
