so it turns out that the injector closest to the drivers side(not sure which number that would make it) is not firing. now what?

now what=just ordered new evo 8 injectors. yay.

Are you sure it wasn't just the harness coming off the injector??

um yes? i was sitting there watching it as i plugged/unplugged the clip

nice d00d. New or used?

oh im sorry, did you say something? you're still on my ignore list...used.

Woot for almost running?

How many miles do you have on the car?

its been running forever, never stopped running. 122k miles. need upper/lower seals and the injectors will be ready to go on.

O hay wait. Are you still driving the car with one crapped out injector, or did the replacements arrive? Or did I wave back to some totally random person on Centerville Road today? :eek:

hahahahahahaha im driving it with a dead injector and that was me you waved to.

Have you tired to swap the injector from cyinder 1 to cylinder 2? I don't think your problem is the injector. I think your problem has to do with the injector resistor box, little silver box, mounted below evap purge and the egr valve, on the firewall.

why do you think that? pulling the clip from the injector did not change the way the car ran as opposed to the other 3 injectors. either way i'm putting in the evo injectors because from what i've read they flow closer to 600cc and have the advantage of being an OE part. i just need upper and lower seals for them.

Did you switch the injectors to make sure it was just the injector? Or did you just pull the clip? What are you tuning with, and were they stock injectors?

i didnt switch the injectors yet because i was waiting for all the hardware for the new ones to pull everything apart. im using an safc and they are RC 550cc injectors in there now. I've heard plenty of horror stories about these injectors so thats why i'm not opposed to thinking one went bad.

Even still, swapping them would tell you alot. It's not really difficult and can be done in about 15 mins. Swap 'em and see what happens, if it's still being problematic, you'll have some direction and newer injectors to run them against, or you'll limit your problem to injectors. Might as well eliminate some of the options in the mean time.

i agree with you. i just dont want to be pulling them apart twice so thats why im waiting to do it, thats all.

Fair 'nuff, keep us posted. Good luck.

thanks man. i called mitsu today cause i was gonna stop by and pick up the seals i needed and those idiots wanted to charge me $5 a piece. they are such bastards, i told them i was gonna buy them somewhere else cause thats ridiculous lol

The only thing you have done is verified that there is power to the other three injectors, what about cylinder one? This shouldn't take more than 20min. tops, and you don't have to take any injectors out.

You'll need a multimeter, pull the injector plug off of the number one cylinder injector, There are two wires ones blue(that's the power wire), the other is green(that's the ground wire) Probe the blue wire, (key one, engine off) there should be 12volts. If there is, than switch your multimeter over to ohms, ohm out the injector. I don't know the spec off the top of my head. But if you ohm out one of the good injectors first, you can get a good idea of what number you want to see. Three, if you have power at the injector 12volts, and good ohm reading on the injector(should be something like 10-20ohms), than you need you verify the ground. The green wire off the injector harness is a straight uninterrupted wire from the injector to the ECU, So if you have power, and good ohms, than you can ohm out the green wire between the injector and ECU. To see if its possibly broken. Or possibly the ECU internal injector driver is faulty.

EDIT: Resistance of injectors is 2-3 ohms. They are low impedance.
