you are so new. headwork? ?why???
anyways, if this is SR, make sure your orange start wire is connected, your wiring to the ECCS relay is correct ( yes, you can have power to injectors and still have bad wiring to eccs relay)
make sure your cas is installed correctly and your @ tdc for #1 cylinder (sparking #1 and not 4)
make sure fuel pump is coming on, and make sure your plugs are not fuel fouled up.
if you dont have an FSM in front of you (even S14 AUS) then your going to be hunting and guessing
