question about injectors on ka24de

[jpnissans13]

whats the voltage that supplies them. and the resistance. because i have a feeling that #1 injector is acting weird. its like on and off. more off now.

Thanks!

12v positive is constant . the computer pulses 12v negative when it wants injector on. if you read voltage with the two wires at an injector you wont get 12 volts because ground is pulsed.

I have a spectrogram program on my computer and an attachment that looks like a jumper cable end that you hook around a plug wire and the other plugs into the computer and it reads the intensity of the current as it fires each time (you can only do one at a time). anyways it may work for an injector, it will measure each pulse. some of the programs are free online and you can order the clamp thing that reads it for pretty cheap offline as well. plus its pretty cool to watch.
