oh. my bad

so I just checked them and there was ~7ohms of resistance... they arent getting power... I'll check out the wiring diagrams and try to find the issue..

I had a connector not connected... ::) some douche told me it was a dead end lol.. ----... now I have continuity from the ecu to the injector.... time to try it out... ;D

and......... Nothing. :-[


any other ideas?

b18c, neptune rtp, 1000cc injectors, basemap, no codes, wiring checks out fine... good fuel pressure...

try adding some fuel from 1k rpm and down. I had to do that when I went with bigger injectors

so do you have 12v at the injectors now? With key on all the injectors should get 12v and the ecu connects the other pin to ground to fire them. Just checking wasn't sure from reading this.

and here was a diagram jd made for wiring in the resistor box using a distributor plug instead of the 'dead plug' that distributes power.

also do the screw driver trick to see if your injectors are opening or not. maybe they are and like the guy above you just don't have the thing tuned right.

resistor box is wired right..

I am not getting the power to the injectors though.... what relay or fuse should I check??

Im 99% sure its my main relay... of to honda I go... they actually have one in stock :S

pull the cover off and heat up all the solder points with a solder iron. Just reflow them is all you need, I added a little new solder for good measure.

Did you follow the manual on testing the relay? It's pretty simple to test.

You could also just jumper past it and see if you get your 12v then.

Re: Not getting Fuel (methinks)
 
I feel like a dunce, I went and got a new relay and it didnt fix it.... so i popped out my handy test light and went to town, wasnt getting 12v at the resistor box... was inside the firewall... I had a loose connector on the harness. ::) ::) ::) easy fix lol
