Only reason I ask is -if- the lines were crossed during reassembly, your Sporty will never start .. Ask me how I know this.
Recommend, as a sanity check, reviewing the lines:
At the fuel pump:, viewed from above, -> towards back of vehicle:
1) Fuel Tank pressure sensor,
2) Fuel -Return- line,
3) Fuel -Pump- line,
4) Fuel Pump / Fuel level connector.
Would follow the line that leads from the back of the fuel filter, down to the frame rail, note (which) line it is connected to,
Make sure it matches up with the (same) line at the back of the vehicle .. Note: viewing at the back / the fuel tank access port, the (top) line running is the rear Brake line, so count (1) down to match up..
( If this is review, Thanks for reading anyways.

)
If all good, you could try -disconnecting- both battery cables, and (re-seating) both the MAIN and FUEL PUMP relays,
And check the engine Coolant Temp (ECT) sensor wiring, follow the top radiator hose to the thermostat block, sensor on right side - a bad ECT sensor or wiring connection will cause the ECM to read (-50), that also can cause a no start condition,
Some things to try,
