2005 Cadillac STS v6 Injector #4 misfire now an open?
 

Hello,

I had an Injector #4 misfire condition on my 2005 Cadillac STS v6.

I replaced the injector with a new one and now it is showing a P0204 Injector Circut Open?

Some have mentioned the connector may be bad and I do not see any obvoius wire breaks?

I also measured the ohms on two new injectors and they read about 13 ohms, do not know that this proves anything.

Any ideas as to the issue?

Thank you!
