try the noids, if they don't flash, just swap in the stock ecu, and see if they flash.

the commander should also say 13brew I believe, it's been awhile since I drove my car, but I know it makes reference to the fd specifically

yeah hook up the noids and crank the car over. The wires may have no breaks in them, but if the ECU isnt making a circuit through them, theres your problem. *knock on wood*

You busy tomorrow fucker? I'll get the light and the beer. https://www.nopistons.com/forums/pub...#>/biggrin.png

unless you plug the noid lights in and crank it over, you wont know for sure. If they dont pulse you only have a few things that coule be at fault.



So youre getting continuous power to the injectors?!

if you are SURE youre getting power to the injectors then its a ground problem. But without using those noids i dont know how else youre gonna test it by yourself.

Thanks for your help. I'm gonna do all that. https://www.nopistons.com/forums/pub...#>/biggrin.png https://www.nopistons.com/forums/pub...#>/biggrin.png

It does say 13BREW.. That I'm sure of.. I guess I never thought it could be the ECU.. As it was unopened.. Ever..



So if I get the lights, and there's no pulse (which I'm pretty sure there won't be) where should I go from there?



Oh, I owe you guys all beer. https://www.nopistons.com/forums/pub...IR#>/smile.png

sidewinder makes a good point. You can't be sure of anything yet really. Just becouse you have 12v+ with the key on, does not mean it has to be there while you crank it, a short, or bad connection somewhere could cause you to loose 12v when you crank. However that is a SLIM possibility..



Here is a question,,,, are you sure your injectors are the right ones? right resistance?? if they are wrong, then possibly putting the grounds together are correcting the resistance problem. Just a thought.......

They are stock injectors.

if you get no puls with the noids, I would do this.



with a meter go from the positve injector wire to ground, have someone crank the car and make sure you have 12v+ constant.



if you do go from injector - to the battery positive, crank, and check for the meter to go from 12,0,12,0



if it does'nt, I'll say try the ecu swap, or consider my injector theory

Yeah... it all makes sense. I hope to learn more with the noid light..



I know the injectors are right.. They are clean stock 550's. https://www.nopistons.com/forums/pub..._DIR#>/sad.png

Thanks I'll try those.
