Also what size are they?


Thanks.

 

Saturation, I do not know of any Peak and Hold Injectors on Asian cars. (we wont mention TBI) Some Nissans look different on a scope pattern though.

You will have power on both sides of your injectors if you use a multimeter to test for power, your meter leads act as a ground through your meter so your meter makes you think the ground side is hot, the injector is a coil, actually a solenoid, this solenoid (coil winding) has resistance, the fact that is has resistance is what keeps the circuit from burning up when the ground is given within the ECM via the injector driver (transistor / resistor combo, this combo is also what makes the blown driver repairable).

This fact of the meter (very high resistance) showing power on both sides gives many techs the fits but they arent thinking of the meter giving a path to ground (very low current, not enough to power up the injector). On your Honda, your saturation injector is concidered to be ground side controlled, all that is needed to make it work is giving its circuit a (very low resistance) ground, its powered up, the solenoid magnetizes attracting the pintle upward, allowing fuel to squirt for 'X' amount of milli seconds, then the ECM releases the ground and the pintle closes with the assistance of a return spring and fuel pressure pushing down on the pintle also.

Depending on the design characteristics, part number used on each vehicle compared to which type of driver is used in the ECM, there may be a need for an external series resistor to increase resistance to each injector solenoid coil thus lowering the amount of current allowed to flow through the injector toward the ECM and killing the driver itself. This style is also ground side controlled.

I was bored, sorry for the extra theory, I may need to came back here some day and copy paste this crap for someone else actually asking for some theory. All of this ground side control of course assumes that the key is on and the engine is running, we wont get into what makes it squirt for 'X' milli seconds. But to flow test all you need to do is remove it from the car, power one up with a hot and a ground on a bench flow tester, add some fuel flow and off you go for 'X' amount of seconds. Doing it on the car manually is called a fuel pressure leak down test, a bi-directional scanner on newer ECM's can do this test. OK ENOUGH CRAP ALREADY

Sizes are measured in CC's that they deliver under a standard fuel pressure / volumn / voltage / time formula, I do not know anything about that part of your question, sorry. For performance, you buy bigger CC injectors and a power fuel controller (Power FC) and map it yourself (beware of injector resistances please).

 

what? 1994 honda accord is peak and hold style

indeed, peak and hold 240cc injectors.

 

uh 235cc I believe but same difference

I'm pretty sure it's 240cc... but like you said, basically the same thing.

 

Thanks everyone, thats what I needed.
