I have an integra GSR. I hooked up my new injectors, and wired up the SMC. set the SMC to about 30% correction(my turbo is not on yet, just trying to get ahead of the game)… fired her up, and she ran STRONG and fine for about 20 seconds. then the RPM dropped, and it was idling really weird, then it quit. now it won't run. I crank it, and it's TRYING to kick over, it keeps stumbling, but it just won't kick over. what's up? do you know?

I double checked all my connections at the ECM, and it's all good. also, when I was wiring my clips and box up, as long as I have the resistor pack wires connected to the positive wires leading to the injectors, does it matter which way the injectors are hooked up? I mean is it like a light bulb, how it doesn't matter which terminal on the injector the positive wire is hooked up to?

 

I'm pretty sure it does matter what side of the injector the positive wire goes on, because the voltage is pulsed DC not AC (like a lightbulb). If an injector operates like a solenoid valve (which I think it does) than reversing the current flow through it would close it rather than open it.

If your question was which side of the injector to wire the resistor pack on, that doesn't matter.

 

ok, I finally got some codes from it. it has a 71, 73, and 74 code. these are random misfire codes? could that mean that I have the injectors hooked up wrong? how do I know which terminal on the injector gets the positive wire? my stock injectors have a + sign on them in the same spot the DSM injectors do. the only thing is that when my car is hooked up sotck with stoick injectors before the new clips and all, the positive wire goes to the side of each coneector that does NOT have a + sign. what's the deal?

 

The positive wires are the yellow/black. The RED, YELLOW, BROWN and BLUE are the signal wires. You should place the resistors on the yellow/black wires.
After you make sure the wires are hooked up right, leave all of the injectors disconnected and one at a time, hook up a light bulb to each clip and see if you are getting signal to the injector (while cranking the engine. might need help). If you have signal, now using an ohm meter, check your resistance on the injectors. Should be close to 2.6.
If you are getting signal, and your injectors are showing resistance, hook up your clips, disconnect your ECU/backup fuse for a minute and try to start it up.
If it still doesn't start, gp to the sparkplugs...

Is your problem fixed?

 

I actually had it too lean. the SMC made the MAP voltage so low, the ECM didn't even know what to do with it.

hell of a thing.

 

No. That is dumb.

 

So you just made it more rich? Did you get your turbo yet?
