How many ohms should the fuel injector check?

Question edited to what I think you thought you were saying :>D

All questions need 'year make model' please as first 3 words.

If you manual says the specs are 11 to 14 Ohms and your is 18 Ohms, if it out of spec and creating too much resistance.

Its telling you the P.C.M /computer is detecting a problem with fuel delivery on injector #2.This dosen't mean the injector is is bad it means its not getting enough fuel .It could be a lot of reasons but the first thing I would do replace the inline fuel filter from the tank to the engine this can restrict fuel flow to the regular witch will drop the fuel pressure to the injectors .The filter likely clear up the problem bot fuel pumps don't last for ever and clogged shorten there lives.

DTC P0202:Fuel Injector #2 Control Circuit .You could have an open in the wiring or in the fuel injector coil windings ! Check for voltage at the pink wire . The other wire comes from the PCM , a transistor inside the pcm turns the injector on an off by grounding the circuit . You can test this by hooking up a test light to battery positive an the other pointy end touch to a T pin probed into that terminal at the PCM . With engine cranking the test light should flash . You should also ohm check injector coil ! the resistance of each fuel injector should be 11-14 ohms.

Testing Fuel Injectors Fast

Did you check voltage and ground for the other injectors to see what your losing, voltage or ground? Do an ohms test on all fuel injectors, see if reading is close to the same? I'm just wondering if you have a faulty fuel injector? The ohms reading should be close to the same for all fuel injectors. #4 may have a problem? Did you try disconnecting #4 injector for a second, to see if others would start working?
Can you check for applicable trouble codes? To check codes, yourself, at the least, you need an obd2 code reader.
Are you missing anything else, engine cranking you have good spark at all the spark plugs? You used a gage and you have proper fuel pressure, engine cranking?

If you have fuel coming out of the lines when you are cranking the engine then your fuel pump is working. You should only get a small burst of fuel when you first turn the key on and then nothing while the key is on, the ECU only tells the fuel pump to turn on when cranking and when it can see cam and crank sensor signals while the engine is running. The small burst of fuel you may or may not have experienced is only to prime the fuel rails. To test your injectors, you can buy what is called a "noid" light. They have them at most stores that have a good tool/automotive section, such as sears. You unplug one injector with the engine off, plug the noid light into the injector connector (harness side going to injector). Then start or crank the engine over and see if you can see the light pulse on and of very fast. You may need two people due to limited visibility while cranking the engine. Repeat this for the rest of the injectors. If you have an "ohm" meter, you can ohm check the injectors by disconnecting each one and touching the pins inside the connector cavity on each injector. The ohm reading should read between 5-20 ohms. I hope this info helps!

There are multiple ways to test fuel injectors. The quickest is with an ohm meter, but it's less accurate than using more sophisticated equipment. With an ohm meter connected to the terminals of the injector itself, the meter should read about 14 ohms. Also, you'll need a test light to check the circuits going to them. With a test light connected to ground, disconnect all fuel injectors and crank the engine. One terminal at each injector connector should turn the light on. With the test light connected to the positive battery terminal, crank the engine again and check to see that there is a flashing light at the opposite terminal.
What sort of problem are you having that you want to test the injectors?

Check the resistance across the injector terminals with an ohm meter. The resistance should be pretty low, a few ohms, but all manufacturers have their own specifications. Check what the other injectors read for ohms, then compare that with your suspect injector-if way out of range of the others, it is probably bad.
If you put your finger on the injector connector with engine running, you should or might be le to feel it pulse. If you can feel or hear the pulsing, it is probably good, barring any mechanical damage to it. When it pulses, because the computer momentarily grounds that injector's circuit, the injector's pintle on the bottom is raised, allowing fuel under pressure to be sprayed out.

use a digital volt meter,put it on the ohm scale check number 2 fuel injector should be 11 to 16 ohms if not reads zero fuel injector faulty.if numbe 2 fuel injector okay.use noid light hook it to fuel injector electrical connector with fuel injector disconnected and see if pcm is firing the fuel injector noid light should blink when cranking the engine.if light steady pcm not firing 2 fuel injector,if noid light dont light up.there is a open in the wiring connector 2 fuel injector 2. if fuel injector okay,check spark plug, carbon foul you have a bad ignition coil or wire if you see oil on spark plug you have worn piston ring or leaking valve guides allowing oil to foul out spark plug.do a compression test check compression to see condition of the cylinder.

Be sure to check the injectors for a short. I found #1 injector bad when I disconnected the harness from it and the engine fired up. An ohms check verified the short, should be about 12 ohms, mine was 2 ohms. I also saw a response that indicated that the ECM controlled the injectors on the positive side of the harness. This is in error. The ECM controls the injector by grounding the negative side with a quad driver.

the first thing to check is the fuel filter. but i will assume you have replaced it already and you have opened a line at the fuel rail and got fuel their. you put some gas in the intake and it started then died. that is why you know you are not getting fuel to the engine . you now need to measure the injector resistance. remove the connectors from all the injectors then with a ohm meter set to 2k ohms test the two pins on each injector all 8 of them they should be with in 1.0 ohm of each other. if you find one with low reading it is shorted and will need to be replaced.
