Very confusing problem accord with H22
Alright so long story short my motor in my 93 accord (turbo JDM H22) starting loosing compression in cylinder#1 so i pulled that motor out and replaced it with yet another good H22 last week. i just got everything back together and the damn thing wont start. it turns over but wont start. before pulling the motor i made sure i labeled all of my connectors on the wiring harness (even though this is like my 10th swap lol). I tested for spark i have good spark on all cylinders but when it comes to fuel this is where it starts confusing me, i have good fuel to the fuel rail and injectors but the injectors dont seem to be firing or atleast not correctly. I tested each injector plug with a NOID light and instead of a normal steady pulse i get a sparatic pulse where the light sometimes lights up, sometimes doesnt, sometimes light up bright sometimes dim. Ive swapped my injector resistor box with a known good one from my friends H22 accord and it didnt change anything. the only other thing i know that could possibly control the injectors is the ECU itself which is a chipped P28 tuned on chrome by Scotty at Mainstream performance. Everything worked perfectly before i pulled my old motor (except for the lose of compression in 1 cylinder). i havent made any changes other than the motor itself. i made sure i disconected the battery before messing with the harness, and im not getting any codes. Also i have triple checked the timing on the motor and it is dead on. all connectors are getting the right voltage and continuity
