wiring diagram of fuel injectors?

[BustedS13]

so, my number one injector isn't firingand after playing with a voltmeter, i found that no current is going to it. SO, i need a diagram or some insight on where the wires run.... any help would be greatly appreciated, thanks in advance!

it probably gets its signal from the pcm. get a noid light and connect it to your injector connetor if it does not flash u have an open. which means something is not connected... ex cut wire, loose connector.. 1. check your connetors to your injectors. as for the diagram i dont got nun.... oh and if the noid light does flash ur injector is dead ... the pcm may ground ur injectors .........






Funny how u get left hanging when u ask about electric... lol

you had zero? are you sure the injector isn't shot? You should have 10.8 kiloohms running through it if it is in running condition. If it has nothing, then it isn't your wiring but the injector itself.

well, i didn't look at the voltmeter, my dad was on that end... but i swapped injectors and the problem stayed in the #1 cylinder. i get spark, plugs are fine, but the voltage on the #1 plug is diff from the other 3.

There are a couple of things to look at when dealing with the injectors.
Intake air leaks, Bad O2 sensors, faulty injectors themselves, exhaust fuel leaks, bad or incorrect fuel pressure, fuel starvation, or an ailing MAFs.

Clean out the injector plugs from all of the corrosion with a battery terminal anti-corrosive of sorts.

As far as getting deeper into the injector issue, the injector circuit may be open or shorted or maybe even the ignition secondary circuit. A faulty injector can and will eventually lead to more issue like 3 way cat issues and more...

The ECM color code from the injector #1 is W/B...or white with a black stripe.

so.... does the wire run from the injector back to the ecm, which i'm assuming is the cpu behind the passenger kick panel? if so, i can get this shit fixed in like an hour....
