E30 Overfueling - What could be causing it ?

[Nadia]

Hi Fanatics Any ideas ! What could be causing my E30 87 model to fuel constantly - injectors are staying open- computer box has been changed, engine is getting flooded with fuel- 90 wiring loom.
Tried so far -changed airflow,computer box, fuel pressure regulator,fuel relay. Thanx:hammerhead:
