Cm2350 injector coil resistance
Does anyone know the stock resistance of the injector coils? The higher my fuel pressure gets the more of a skip I get so I've got an injector that's acting stupid or two but it holds fuel pressure like a champ barely loses anything so it's not a leak down issue so I'm thinking it might be possibly one of the injector coils just failing.

So I'd like to see if I can check the resistance of the coils and possibly find it since plugging off fuel injectors won't find it.

You can run injector performance test to check which injector is failing. Then move injectors to other cylinder. Don't forget to change injector codes in Insite. If failing follows with injector so injector is bad, if same cylinder fail look in to ESM or injector harness or valves.

The performance test passes all the injectors but when you do a fuel leak down test the engine starts skipping and jumping around all over the place but when you turn the key off turn it back on to watch the fuel pressure fuel pressure doesn't move more than like a thousand PSI in 5 minutes

Ok . You can measure all 6 injector coil resistance to compare. Any out of line will give you the answer.
Do you monitoring relief valve leak during the test?

Replaced relief valve this winter do to losses doing leak down test now she looses about 500-750 psi in about 4-5min
