FLSC

Please give advice if u can because im running out of ideas and money!!! Background... 1992 SC400 with a performance cam 216000 on the clock. It would not start so I began my journey down the rabbit hole... changed fuel pump, fuel ecu behind seat, ignition coil mounted on the motor, new battery, turns but will not start , bought a new EFI relay 1(round one 4 pins), took it out with key on, replaced heard a click, fired right up?????? What in the hell do I do next? Please give me your advice as this sight has helped me diagnose and eliminate most of the ideas I have come up with
