ICM under the cap fires the injectors. Nice build!
If there is 12 volts at the injectors, then I would say that the ECM grounds them to fire. I can't remember for sure. I know that it has to see the signal from the ICM to fire the injectors.What tells the injectors to open other than the ecu ? No power from the comp ? Would this be an bad esc module ?
There’s a way to test it with a multi meter just got dark and cold on me I’ll get back at it tomorrow I’m almost sure that’s what it is .If there is 12 volts at the injectors, then I would say that the ECM grounds them to fire.

I have checked injectors by using jumper wires to pulse power and ground to them. I just unplug them and used a 12 cordless tool battery. Not sure if this test will tell you enough though.
Thanks man I’ve got some time in .ICM under the cap fires the injectors. Nice build!
