Correct Procedure For Testing Injector Ohm's - Third Generation F-Body Message Boards

I did a search but couldn't find the guide that tells you how to test the Ohm's on the injectors.

I want to run a random check on all of my injectors and need the details.

Engine running or off? Piggyback the connector or unplug and test injectors directly?

Hot or cold?

Details!

Engine off, unplug the connector. Its easier to test them cold but you will get a better test if you do it while the engine is warm. Eletrical devices tend to fail when they get hot. Wear gloves so you dont get burned on the hot intake parts.

Thanks!

So to my understanding, 15 ohms is what I'm shooting for? Would the reading be the same for the 9th injector?

the 9th injector is a solenoid valve not a injector, it either opens or closes and there is no pulse to run it. The ohms on that coil should be 3.5. here is a video on how to ohm check injectors
