2002 INTERNATIONAL 4300 DT466 NO START COLD......STARTS AT 50* BUT NOT AT 40*.....

MY LITTLE INTERNATIONAL 4300 WITH THE DT466 HAS ALWAYS BEEN A VERY GOOD STARTING, RUNNING AND DRIVING TRUCK....UNTIL A COUPLE WEEKS AGO WHEN THE TEMPS DROPPED BELOW 50*. ONCE IT HIT 40* IT WOULDNT START BUT IF THE TEMP CAME UP JUST TO 50* IT WOULD START LIKE IT ALWAYS DID. ALL THE PIECES OF THE PUZZLE POINTED ONE WAY UNTIL.......WELL, YOU WILL SEE! HOPE YOU ENJOY!

[@MrTruckerf]

I admire your ability to diagnose and remedy tough problems. I hate electrical issues. I have seen you say you like them because they can lead to getting a good deal on an easy-to-fix truck. TRUE!

[@mattcat231]

Before i begin, let me tell you that you are the MVP of the year in my book, just for showing how to shut off that aweful beeping!!!! I never knew this!!! THANK YOU!!!!! Literally just went through this on a friend's 04 international box truck, had to give it a spritz of the ole magic in a can on any cold start, no matter the temperature. I also noticed the RPM's dropping out on my scantool, so out came my DVOM, powers and grounds check, found the entire ECM system to be lower voltage than battery voltage, so i found that fuse, which had the holder replaced with crimp on female spade connectors and they disintegrated upon moving it. An inline fuse holder, some solder, self sealing heat shrink, and tape in a can later, that thing runs SO much better, starts every time, and now get 8mpg over the 5 it was getting!

[@j.c.smithprojects]

if i was smarter, i would have picked up on the issue in the first crank with the scanner on. after reviewing, it was right there in front of me. live and learn.

[@mattcat231]

@@j.c.smithprojects There's many ways to get to 10, and it doesn't matter how you get there, as long as you do. 5 possible things wrong, 4 things checked, 1 middle of the night idea equals 10, you got there, and that's what matters!

Mr JC Very informative video. Stay safe

[@cbforme]

Excellent explanation and fixing of a problem and bringing us along multiple days. I knew there was a fuse in the battery box that would burn out for a no start but didn’t know that fuse was for the ecm.

[@Ezrider359]

First step in diagnosis is understanding how it's supposed to work when it works properly. Without understanding that first any diagnosis is a uphill Battle. Iv seen that same issue on freightliners a few times battery box is a prime place for corrosion.

[@MetallicAH2O]

At the dealer, we found lots of problems with that ECM power/ground harness. We got in the habit of hardwiring the three plus connectors that international put throughout the whole length of the harness making it essentially one whole fused harness running directly from the battery box to where it needed to go. I believe there were connectors at the battery box, the flywheel housing, and the engine bay and all were prone to corrosion, poor pin fitment, general damage, and bad crimps leading to all sorts of weird issues.

[@pedrotheswift5937]

And today I learnt something... great bit of Teaching JC!

[@ericcorse]

A good fix that was relatively pain free. This ought to help some folks out.

[@americanoverlander1116]

I have two of these trucks. An 03 and an 05. The power you're getting from the battery to the ECM and the IDM is referred to as clean power. It is power that is distributed pre-fuse box. The connection you found is critical. Also check your ground connections.They run from the battery, to the starter and from the starter ground lug to the engine block and the frame. Corrosion will corrupt the continuity and give you the same type issue that corrode fuse connection did. A steel brush clean up goes far on those connections.

[@richardhoneywell7411]

Dear J.C. Smith projects. 👍👌👏 Very well done again and as always. Congrats for finding and fixing the problem. 2) Please kindly allow me to suggest to not have so many keys on your keychain. The weight pulling on the ignition switch is able to wear the lock out respectively destroy the ignition switch. Even more more if it is one of the newer infrared keys/switches/locks (please don't ask me why I know, sigh). Thanks a lot for making teaching explaining recording editing uploading and sharing. Best regards luck and health to all of you.

[@j.c.smithprojects]

the keys you saw were on a carabiner. there are keys for multiple properties and multiple trucks that i drive on a regular basis. i use the carabiner so i can remove the keys im using at the time and lay the rest to the side. i dont like hearing all those keys jingling as i drive. since i wasnt actually driving in this video, i didnt remove them.

[@haroldlauber6389]

Good to know lesson

[@toddwalther9177]

In my experience if the engine is warm and won't start but will when cold it would most likely be the high pressure oil pump. The corroded fuse and cables in the battery box has caused a few headaches for me. I would imagine it is more common for truck that live in colder climates that use salt.

the green crusties never sleep. constant issue.

[@tinkeringtrucker5196]

Really enjoy your videos JC. I am in the market for a Class 6 or 7 truck for trailer towing. I see quite a few International trucks for sale and remember a comment in one of your older videos about Max Force engines being problematic. Looks like International got in some hot water a while ago with how they were going to attempt to meet the emission requirements. Are there years of International trucks you would recommend I avoid? Keep up the great work!!

I have the same issue usually after it rains tho , have you encountered that ?

[@eddiepatterson5025]

Where the fuse is where you clean it the pigtail itself. Could you take like a ziplock bag or something similar to cover it and use a zip tie to close it up to protect it from the outside elements Do you think that would help it from corrosion problem some. Just wondering if that would help from getting corrosion as much?

[@j.c.smithprojects]

that fuse is in a weatherpack connector and a full cover. it was likely left outside of its holder for some time.

[@dustinuselton1092]

Have you by chance had a dt466 not turn off with the key? All gauges shut down and powers off but truck keeps running. Changed both relays under the hood a few in the fuse box on pass side. Still doing it. It’s an 09 Durastar MaxxForce

[@j.c.smithprojects]

either the ecm isnt shutting down or its running of of oil instead of fuel. i would start with a pinout of the ecm. check powers AND grounds. find out if the pins that supply power are still energized with the key off. i would have to look at the schematic to be more helpful.

[@dustinuselton1092]

Thanks so much. But yeah sometimes if I punch the accelerator when it does that it will shut down sometimes it doesn’t shut right off.

everything expands and contracts due to temperature. the load put on that fuse and terminals along with ambient temperature was enough to cause it make and break connection because of that expansion.
