The engine will run with voltage down to 9.0. Normal voltage running should be about 13.5 after the glow plugs release. I wouldn’t trust a Dorman CPS. Get a real International CPS. Is your IPR magnet in place with the tin nut tight?

Yes the IPR magnet is in place and the tin nut is tight. Now that I think of it the IPR is a freaking Dorman also. Should I change both IPR and CPS. I found the loss of charge. I had a blown fuse that wasn't energizing the exciter wire to the alternator.

Did you see if the oil pattens from the injectors on both banks are the same now? Have you tried unplugging other sensors? They all share a reference voltage so if any one of them are acting up, they can drag the others down. The EBP is the usual culprit, but MAP, oil temp, air temp all can be faulty. Change the CPS to your original if you can.

Supposed to be whose? Anyway, most of us remove the springs. I’ve never seen any hard start issues. Can you explain why that might be so or direct me to an article that backs that up?
