for a injector to be on constantly then either the wiring loom to the injectors is damaged and shorted out or one or more of the injectors is damaged
if the ECU or other sensor input was demanding the fuel then the injector would 'click' or pulse on and off as this is the normal operation
So I'd suggest the next step is to check wiring loom for damage
if thats OK then I'd pull the spark plugs to see if you can identify which injector is on all the time
do you still need help?

if the mass airflow sensor is faulty then this too can result in the injectors overfuelling
The main thing is when measuring the resistance of the AFM (pins 2 to 4) while moving the flap the resistance changes in steps which many people see as a fault.When measuring the output voltage, the voltage should change smoothly from about 0.3 volts (flap fully closed) to about 4.25v (flap fully open).If the voltage changes suddenly at any point of the travel of the flap then the carbon track inside the AFM needs cleaning or the wiper needs to be bent slightly so as to travel along a new section of the carbon track.

it should be at the top
in the tool bar with the bold and underline buttons
