NO START Diagnostic 2 | Mitsubishi Fuso 4P10

Round two of diagnostics for the no start condition that has come up on our truck. This time I dig more into the electrical and sensor side of things, and make at least one mistake!
Things like this sure can be frustrating, but the only way to get it resolved is to push through and keep systematically verifying things. Eventually, I should hit the cause.
Again, no links in this video, I appreciate your support!

Haha, was I the person. I watched this video when it was posted and was not able to leave a comment. When you have vehicle issues, it stops the house build! 😢 The worst. Watching your newest video now!

I’ve always got vehicle issues, if it’s not on this vehicle it’s on another! (Sometimes more than one at once!) 🤣

Good troubleshooting, Bruce. You DO have a 5v source. Any of your phone/kindle chargers put out 5v. I bought a bunch of 5 and 12v power supplies from Ebay back when things were super cheap and shipped free. Some were 12v in/5v out or 5v in and 3v/5v/9v/12v out and were about a buck apiece.

Never even thought of a USB for power!

Good job and its good you show how sometimes its can be a maze to diagnose. When you check your resistance did you check your reference voltage and ground from the computer? Than start with thing you know it already bad / more probable otherwise you can look for chimeras. You have def : temperatures sensor fault, start with that. You can put a resistance or old part / switch part or a potentiometer to give a good signal and test. Its already broken so you will have to repair it anyway and there are a posibility that is your problem.

Only problem is I don’t know what the correct resistance is for the DEF level sensor (not temp). I have new sensors on the way for the exhaust, so hopefully that was what was causing it.

One low-budget suggestion: You should be able to confirm whether or not the injectors are firing with a stethoscope. I have a Lisle that works great for isolating bearing noise. Will need something fancier to see if they're firing at the right time, though.

One of the next things I’ll be doing is pulling the connectors off and sticking LED’s in them to see if they all flash…

You are brilliant Bruce! I could never figure out all the crap you do. I did have to adjust my cab tension bolt also because I could barely budge my cab over but it is custom built with a lot of added weight too!I thought I was just getting old and weak...

Have you tried with the doors open? Makes the biggest difference!

He probably cheats with a complete service manual for the beastie. Bruce is no dummy. ;)

LOL, if I could cheat on this one I would!!!

I think with the injector pipes off and the system open then pressure is lower? Can you get hold of a scope to probe the injector pulse?

I have a 2007 Fuso FG 4x4 that has “issues.” Zeus also has a slow battery drain that I can’t figure out. Sometime he won’t start… I’m cheap, so I give the starter a couple light taps with a hammer and he fires up.

Kill switch and or float charger is an easy way to save your batteries 🙃. Starter is a bit more difficult to fix, but could be just a loose wire on the solenoid.

Bruce, I have an EGTsensor for you as well as a dc power supply for 5v reference

I had pproblems with my sensors also and I am gonna guess that is your problem and that is the way they designed this system to disable starting to protect the crappy emissions system.

@BruceandKrista 25 күн бұрын

I hope that’s what it is - just wish they would give a code that says start inhibit due to “X” !!

What's up Bruce. I see you have the Duonic transmission. How's it been holding up? I'm thinking about buying a Mitsubishi canter with the same transmission 2017. How many miles you have on her? Any problems with the transmission so far? Oh and good luck finding and fixing the no-start issue.

@BruceandKrista 21 күн бұрын

So far my ownership only entails working on building the truck, but the twin truck to this one has been collecting miles for the past few years! There is a recall on the transmission, so check with a local dealer if it’s been done on the truck you are looking at.

No start no code is usually immobiliser?

@BruceandKrista 24 күн бұрын

Immobilizer shows a light on the dash during cranking if it’s active… no light… 😔

@paulluggar5964 24 күн бұрын

Ok, check for fuel squirting out of injectors. Then check if fuel has water in it? All basics, sorry if you already checked. 👍

@BruceandKrista 24 күн бұрын

Did that in the previous video - have fuel all the way to the rail…. Computer reads fuel pressure as in range.

@paulluggar5964 24 күн бұрын

But check it's coming out of an injector or bleed pipe....👍

@BruceandKrista 23 күн бұрын

At over 5000 PSI, and with the effort involved in removing injectors, I’m thinking that will be my absolute last resort 😎

Hey, look, dont judge me, i know its potentially the stupidest suggestion so far..... but.... hows the battery in the key? I figure NORMALLY a vehicle shouldnt even turn over if the chip in the key isnt transmitting, but i've heard of stupider design decisions in some of these trucks. Is it possible that the "immobiliser function" still allows the starter to crank but doesnt issue the ignition command? I dont have any examples of a immobiliser system doing it that way, so i can't back up my suggestion. But at this point i think you just need heaps of potentially stupid theories to start whittling down every possible issue

@BruceandKrista 24 күн бұрын

Yup, I wondered if it was the immobilizer, but if the immobilizer is preventing the start, it shows the lock light on the dash when cranking. Changed the battery anyway, no luck!
