Default Ls400 troubles need help!! - Doesn't start

Hi all
im all the way from south africa, and over here we import our lexus motors. So i have one that was built into a nissan hardbody.
Now i have a problem after parking it, it doesnt want to start anymore.
The fuel pump and pressure is correct, but seems as though the injectors dont pulse( if that is correct)
If i do throw fuel directly into the throttle then she starts no problem
Please help guys!!
oh yeah its the 1uz-fe vvti motor and also has the original toyota ecu, no aftermarket system

Suggesting you scan for trouble codes to get an idea what's wrong.

If it runs then maybe bad fuel pump or no injector signal.
