Hello to all, I am a new first time corolla owner and have a question about it.
It's a 99 with the 1.8 1zz engine....It has a misfire that happens at all times,I've checked spark and all 4 wires are getting spark.checked the fuel injectors and number 4 injector does not have a signal so it's not injecting fuel.I checked voltage and I get 12volts to the b/w wire and I also have continuity in the black wire from the injector harness all the way back to the ecu.I went as far as to bypass the harness and run a separate wire from the ecu to the injector and still nothing.it seemed to me I had a bad ecu so I got ahold of another one same numbering and all but still nothing.I'm at a loss.the wiring diagram dosent help much because I have power and continuity.any help or leads would be greatly appreciated!!!!
