smoky corrado vr6 inj problem ?

[myles 0]

lads have a problem here that i am looking for a bit of guidance on.i have an overfuelling problem with my vr6 corrado.

 

removed inlet manifold and i ascertained that no 2 injector was pumping fuel into the cylinder as soon as the ignition was switched on. i switched around the connections with injector 1 and the problem went with the connection. injector is fine but connection is the problem.

 

there is 12v at the injectors when ignition is switched on , including the faulty connection on no2 injector.

 

what is my next course of action ?

 

ecu maybe ?

 

all help greatly appreciated !!!

you should have 12 volts on each injector, and the ecu switches the earth to actuate /trigger the injector to open, so if you have a faulty injector earth wire shorting to ground that will pump fuel into tha cylinder, try checking the earth side of the injector connector with the ecu disconnect and injector disconneted, check top see if the wire has short to ground, with both disconnected.

ECU is kaput I reckon..... dead injector driver.
