Did i ruin my injectors..?

[skyline084]

This is for a 97 honda accord..
I did what this guy did on youtube to attempt cleaning the injectors.

Fluid was spraying through all the injectors when I was doing it, but only one injector will not open/spray while on the car.

Is it possible that my injector burnt out while cleaning?
Now fluid won't squirt through the injector either
There's only one that isn't working now

Depends on the impedance of your injectors. If you have ones that use a dropping resistor and you ran straight 12v to them you have likely destroyed them.

okay yea I've heard that tossed around.. thing is 3 of the 4 still spit fuel .
So wouldn't they all be toast if that were the case?

Pretty sure Honda uses high impedance. It's probably just a bad injector that needs replaced.

I'm pretty sure they're low impedance b.c now the car is running like complete s*** and will only fire on 2 cylinders, sometimes 3.
I get a solid spark out of each ignition wire though.

If you got fluid out of all the injectors, then the injectors should be fine. If they are low impedance, then the only reason it wouldn't fire on the car is a power supply problem to the injectors, a problem with the dropping resistor, a problem with the ECU, or a bad ground.

Well I get a constant 12v to all injectors, and the signal was somewhere around .8 for all of them.

Apply 12v directly can mess up your injectors, so careful if you try doing that test on youtube.. got another injector, problem solved.
