I replaced the ecm and pcm everything was fine for two weeks now im right back to the p0341 and no tach. I’ve replaced both crank and cam sensors and still the same problem truck is causing me a headache

I’ve changed the cam sensor and the crank sensor but the code keeps coming up, I have also chased down all the grounds and cleaned them along with connectors.. I have 5v to the orange at every connector and or plug I’m at a loss for words right now
