ka keeps eating injectors... why?

[0danxQ]

ka with 210k miles on motor

i've changed the o-rings i've replaced injectors with new injectors prolly 4 times these past 3 months

replaced my ecu already in december and seemed to correct the problem

could it be the fuel rail?

what do you mean by "eating" injectors? do they stop working all together? leak? are they becoming clogged? Provide more info so we can help you

On same cylinder or different cylinders. 3 injectors on my KA went bad within 3 months, so I had to replace them one by one. One original injector is still there and works fine somehow.

they stop working all together one at a time. most of the time its cylinder 3 so i'm not sure why. I've noticed it the happening these past few months but this has been going on for 2 years.

Check for excessive heat around the engine... Before installing new injectors make sure they ohm out around 11ohms.

Maybe a wiring issue? Inbetween the ECU and injectors? Maybe find a used fuel rail with injectors in it already in working condition and just replace the rail anyways?

ecu--injector = good and the new ones ohm out fine until they give out maybe a few weeks later... i just dont want to have to replace the fuel rail unless i really have to

its either the fuel injector driver, fuel filter, or the fuel pump. in my case it was the fuel pump, after about 6 months of similar issues to yours, fuel pump crapped out. been good ever since i replaced it with the walbro unit.
