    test light

    tak a test light to the injector plugs to see if they are getting power and then take it from there

    are the injectors even shooting out fuel? They could just be bad. I know it sounds like a long shot but that has happened to me before when I put a ZC into a friend's car. The motor came with crapped out injectors.

    Well before you take the injectors out to see if its shooting fuel. Try to find a stethoscope for automobiles. It looks just like a doctors one but it has a metal needle looking thing on the end. You put it on the injector and listen for the fuel shooting.

    But take the easiest way first: the test light on the injector plugs.

    a test light will only show if they are getting a pulse/power, it won't be able to tell you if the injector is clogged.

    Mike, You didn't touch the wiring for the injectors did you? All you needed to wire in was Vtec, Knock, and 2nd o2 so i'm leaning towards the injectors just being crap.

    Well I meant take the easiest approach first wihich would be the test light to check for power. Instead of pulling them out to see if its shooting.

    ok i tested the wireing with a light tester and the light came on so i took the fuel rail off and pulled the injectors off and looked at the tip of the injectors and they were dry but the fuel rail was full of gas so i am guessing that the injectors are bad but do tell me what are the odds of all 4 of them being bad at the same time?

    you can use LS injectors if you need, but if you got fuel in the rail and the injectors still arent working, check each fuel injector wire going to the ecu, Honda PGM-FI has the injectors powered all the time, the ecu grounds the circuit to open the injector, thats why your test light lit up because they have power when ever the key is on.

    even if the regulator was bad there should still be enough pressure in the system to shoot some fuel, maby not enough, but some.

    having the ECU bolted down or not does not make a differance, if you bolted it down and it ran it may be because some of your wiring connections are bad and you temporarily fixed the problem by moving the wiring around

    Injector Cleaning

    Is there a DIY way to clean your injectors without them being installed..? What I mean is, a way to clean them without something in a can, as in soaking them in some solution or likewise..?
