URGENT: Need electric help, injectors not fireing

[ZaX]

Hi guys

we are working on one sr5 to gt conversion and we have a problem with electrical installation.
Car: SR5, loom
Engine: 4A-GE MAP with all the sensors,injectors, ecu, loom, distributor from AE86 GT.

Car cranks, but it won't start.
Sometimes it's starts with the fuel from the cold start injector.
When I put little fuel in intake manifold it starts and dies.
We have spark on distributor/spark plugs.
Fuel pump is OK, we changed 2 pumps.
Injectors have 12V on connectors.
Injectors are grounded to manifold (4 brown wires). Manifold and head are grounded to chassis. Engine block is grounded to chassis.
ECU is bolted on to the chassis, ECU has 12V.

Instrument cluster is not connected with check engine light, so I can not perform diagnostics.

Any ideas?
