View Full Version : ? about stock sr injectors

08-09-2002, 01:43 AM
I was looking at my friend's red top today and his injectors were side fed and I realized that mines were top fed. Anyone know y? probably just different year? I might of thought that whoever had the engine b4 me might have installed it back onto the fuel rail wrong. http://forums.freshalloy.com/ubbthreads/images/icons/confused.gif

The S13 RWD SR20DET comes with Side Feed 370cc High-ohm injectors. They are usually purple on top. (sometimes dark green, and possibly others)

If your injectors are feeding from the top, then I wonder what sort of computer are you running??? Did you buy an entire engine setup including the computer? Maybe the previous owner put on a top feed fuel rail and bigger injectors.

I am actually using a stock red top ecu(62) right now and the engine seems to be running fine...just except when at start up I'll have to keep my foot on the gas pedal and then drive it around for a bit then it'll idle good without me helping it idle with my foot on the gas pedal. For some reason my car will die after I start up the engine and if I don't help rev up the engine. It'll start up for like several seconds and then sounds like it'll choke then dies.

I also bought the ecu seperate from my engine,tranny,etc...when I bought the sr...I was missing the ignitor,engine harness, and ecu. I just checked the color of the injectors also and they're purple which I'm pretty sure is the stock 370cc's. Do you guys think there's a chance the previous owner may have changed injectors and installed it wrong? Is there anything bad about it if installed incorrectly?

do you have the black/yellow wire hooked up to 12v power? that's what turns on your IACV. maybe it's not working and therefore causing hard cold start.

Oh ok I know which wire is that...let me check up on that and I'll let you know how it goes...thanks

Just wired that black/yellow wire and still the same thing...hard cold start. http://forums.freshalloy.com/ubbthreads/images/icons/confused.gif

I've been driving around a while ago with the black/yellow wire hooked up and it's making my car run like sh|t.

Anyone have any ideas about the injectors? http://forums.freshalloy.com/ubbthreads/images/icons/confused.gif

Side feed injectors can't be installed in a way that would make them appear to be top feed. Either the previous owner replaced the injectors with top feed along with a new fuel rail, or maybe, well, can you provide a picture of your setup? That might help to clear things up.
