Hello, I have a Titan in my shop and I'd like to know if anyone knows what's causing this problem: two injectors aren't receiving ground pulses on the last two injectors on each side. I've already checked fuses, connections, and continuity, but I can't find the problem.

Any information would be greatly appreciated.

Thanks and greetings, comrades.

It's a Nissan Titan V8 5.6
