Does it turn over at all? Check that you've definitely reattached all your earths and your fuses are still good.
See ya

Re: 3SGTE wont start
Which 3SGTE are we talking about? GEN2, 3, 4 or 5? Is it a swap or factory GT/GT-S/Turbo?
Spark means the ECU has power, the engine is seeing signals it needs to do this.
The fuel pump is controlled through a relay that is controlled by the key during initial start up then the ECU controls the relay once it sees the engine is running. Does the pump run when you turn the key to START? You can disconnect the starter relay to make it easier to determine.
The FP and +B may not work if it's been a swap as it's not a direct plug and play for some set ups.
The gearbox has a large ground strap that it needs to complete the circuit for almost all engine functions.
