Good afternoon.
I have an issue where I'm not getting ground to my injectors on 04 Civic EX. I HAVE 12v to the power wires but no ground or pulse. Have good fuel pressure at the rail and spark to the coils. There are no OBD2 codes coming up either. I also noticed that when I test the crank sensor connection that I have 12v to the power wire, continuity to the reference wire but no continuity to the ground. I've checked all the ground point visually and with a multimeter and they are all good. Any help would be great

The grounds for each injector come from the ECU. Check continuity between the injector clips and the ECU and make sure you have no breaks in those wires. If wires are good, the ECU could be bad. Also, do you have a green key immobilizer icon on the instrument cluster ??? If it is illuminated steady, you will not have fuel delivery.

It comes on for a few seconds and goes out when the fuel pump doesn't get its signal. What is the best way to test the continuity between the clip and the ECU? Thanks for any feedback. This is driving me crazy

I have good fuel delivery at the rail but I'm unsure if the chip disables the injector. I tried with both spare keys and still the same thing.

Ok. Figured out this was a bad Cam position sensor. Tested it using a paper clip into the back of the reference wire and the touched the paper clip with a voltage light connected to the battery ground. Replaced the sensor and I now have pulse to the injectors. Noid light confirms the pulse.
