Did you test the injectors through the valve cover not just the pig tail? Also looked like your other pig tail was spliced too.

Sounds like you are making progress!
You can try switching solenoids on the injectors to see of the problem follows that solenoid. But your issue is likely elsewhere. This is just something you can try if you can't seem to find the problem.

Yep I'm getting very close thanks guys. So what's going on now is the front 2 injectors arnt getting power. But the ground side switches are working. And I tried jumping the power from the back 2 injectors and it killed the system. It all started with a bad connection from the idm. Now I ohms check the front 2 injectors. One was 3.2 ohms, the other was 4.7

Ok guys iv narrowed it down. The front 2 injectors are not getting power. And I have a clean connection to the idm. Bad idm ?? 1st injector was 3 ohms 2nd was 4.7 ohms. But this morning they were both 2.9 ohms

What do you mean by "front two"? The forward-most on each side, that is, 1 and 2? Or the two associated with the passenger side forward connector, that is, 1 and 3?

I just did and she's good and I used my volt meter to check the wire and its good. So I'm thinking idm or an injector is making the idm shut them down. What do you think

Did you check continuity from the IDM harness to that injector harness?
