Hey guys all 4 of my injectors stopped firing simultaneously while driving, I have 12v power to the injectors which means it’s not getting signal from ecu. Fuel pump primes and runs, I’m getting good fuel pressure to the rail, pulled rail off and tried to see if injectors would fire and they would not. So I swapped wiring harnesses, swapped Ecu, swapped main relay, checked all fuses, checked all grounds, and everything is good I even swapped injectors thinking maybe something happened and they all fried from a short or something. I am at a loss for what to do and what it could be. I was told maybe to check the wiring coming off the ecu however if I’m not mistaken there are 4 seperate pins for the 4 injectors so it wouldn’t make sense for all 4 to go bad simultaneously. Anybody got any ideas? Car has spark and air, it starts with some starting fluid but only stays running for a few seconds due to injecores not firing. Bone stock d16z6 on hondata

 

Have you attempted to clear/reset the ECU and re-upload your calibration ?

 

i swapped ecus with my friend to see if it was the ecu and it still wasn’t firing so it’s not an ecu issue.
