Sorry. It was just a thought.

They will flow for a while sometimes even when clogged after sitting for a bit.

Yeah if they are dropping to 6ohms then something is going bad, it wants to see roughly around 3.8 ohms per bank... that's estimating 11.5 on all three injectors. Drop one to 6 and you get 2.9 ohms on the bank... Probably too low.

You had said new fuel injectors, I guess you meant new to you?
Maybe you can use some good, old injectors and some of the new?

When my one bad injector shorted out my entire injector circuit, i was able to swap the one bad one with one that tested good albeit used and VOILA the car started again.

I hate to say the weba, but maybe putting back the old injectors might help??? At the very least, you can inspect the wiring for the injectors to insure wiring didn't get pinched between the LIM and the UIM??? I know this sounds like i'm grasping at straws here but everything needs to be looked at especially something that has been changed and seemed to work fine before your problems.

New doesn't mean good. Even if they are brand new. I just had a brand new bad part trying to find an electrical problem on my truck.

weba, sounds like you have done all of the logical troubleshooting. Then it is time to go back and re-check all of the "known" good parts. That is how I found mine.

Injectors sound like the next thing to start with. I have "known" good 3100 injectors that were great when removed in 2009 if they could be of any help.

I got another set of injectors from Rockauto (brand: Standard) , and now the car runs smoother than I can ever remember it running, seems like the issue is gone. Also exhaust sounds different.

Also, almost month without car in fall, sucked.
