Also check your Fuel pressure. I know you said you looked at the sock/pump w.e check the pressure.
Check voltage at injectors. Put your ECU in another SR car and see if they have any problems. Do not place a working ecu in yours, you may fry it.
Also make sure you have the correct firing order on your spark plugs.
Ignition timing must me set at TDC on cylinder one. Make sure you are tdc cyl 1 exhaust stroke also.
