‘99 IH 4700 shutting off & no start

Hey guys. I’ve had issues with my truck shutting off. Dt466e. I had replaced the cam sensor last year with one from advance auto for the 7.3. That turned out to be an issue. I replaced it with an oem from international. Over the summer it would shut off while driving. Most time you could just start it back up. The times it would not start back up I would swap the starter relay and ecm relays under the hood and it would start. It would do it again and I’d swap them back. I replaced both of them with oem relays. It’s been fine ever since. Last week it would not start. Key you make the click bit not start. Swapping relays didn’t help. It eventually started and I assumed it was the starter, I haven’t replaced that yet. I was headed out the other morning and it shut off again! Swapped relays and it started. During the day it would shut of momentarily (like a miss - felt like I let off the fuel and got back on it).

Could those relays be bad again? Is there something that could be making the relays bad? Any other relays I’m missing?

Any help is appreciated!
Thanks!!!

I can tell you this about the DT466E cam sensors. I went through a couple before I could get the dam thing to run over a month at a time...

On the no start it sounds like it could be an intermittent cable or battery connection problem causing low voltage to the relays.. Might put a load tester on the batteries also...

What would explain the swapping of the relays that makes it start?

I plan on cleaning all the battery/start connections when the weather gets better. Do you think this is one issue or two separate issues just occurring at the same time?

Thanks!

That could be as simple as moving the cables when changing relays. One corroded terminal will cause an intermittent connection and will still look good from the outside.

Low voltage doesn't arc across and weld together like a higher voltage of 120 volts for example. I'm sure you've heard of folks with dirty battery terminals that carry a hammer in the car. Sometimes the car will start and other times it won't so they just pound on the battery terminal and viola, the car starts.

The click you get when trying to start means low voltage at the starter or solenoid usually caused by bad batteries or wire/terminal connection..

I've seen battery posts rounded off and pounded down flush into the top of the battery before the battery finally quits. It's much easier to remove and just clean the post in the first place.. Intermittent electrical problems are akin to witchcraft, if you're not careful it will drive you crazy.. Don't ask me how I know...

Thanks for the input, I’ll check those relay plugs this week and see how they look, maybe th terminals are loose or corroded. Would the starter relay cause it to shut off though?

The relay, not by itself but low voltage could very well cause an engine stall.. I'd still be looking at the cam sensor tho..

No response as to what the problem was in over 2 weeks.. I think threads like this are the reason most everybody has left here.. Sad...

I agree, it's also why the same things get discussed again and again. Lack of what the solution was.
On the positive side, maybe that did it and he's been busy hauling loads?
