Default Re: SR20DET fuel issue's....Please help....I dont ask much.....

JGY topfeed fuel rail......
JWT POP upgrade tuned for 50# MSD's , 7800 rev cut, 15*BTC , Z32 MAF, and the usual other shit as in speed cut and etc.....

I found out tonight that the voltage on the injector harness was 10.3V at initial turn on and dropped down too is 3.4V per injector, and its making a good ground (seeing as how the ground is made by the ECU) But my injectors are not spraying, I figured they might be fuct injectors so i hooked up the stock fuel rail and injectors and still no spray, I'm thinking i got a bad ECU, meaning the ECU is not sending a output signal to pulse the injectors, but I have spark and the spark works off of the same timming.....

My timming is perfect, and I cant think of any wirring issues I have other than the tranny harness not being completely hooked up..... Compression was 175 all around as well....My last SR was at 140 so the compression on this one is better....I can check continuity but I dont see the point after seeing that the stockers didnt work either....I happened to find a loose conection in my relay harness (its an S14 with an S13 SR in it) and thats why i wasnt getting any power to the injectors....And yes a test light will work and slowly dim at initial on position.....Whats sad is I work for nissan as an apprentice tech, and i have access to the Nissan scanner but it does not read my ECU because the car has to be running in order for you to check work support (monitor all the systems that are electrical) I have an over abundance of information but none of it is seeming to work......I hate life at the moment.....

I dunno man, I'm trying not to give up but its getting rather discouraging.....
