Ok so i went to go start up my SR20DET as i just built a new one and when i went to start it and begin the break in process it was only firing on two cylinders. So i did the obvious checked for spark- Good, checked plugs- Good. So then i went to fuel and what I found was the injectors for cylinders 2 and 3 were not firing. I had a new tune on an untested ecu so i switched the ecu with a known good one because i know some rom tunes end up frying injector drivers and had the same problem. This harness was not changed and had a sr20 in it running great before. I will begin to start tracing down from the injectors this weekend till i find the problem but wanted to know if anyone had any ideas on shortening that process. Thanks guys!
