Im having a problem on mine, same engine i checked for spark and compression all check out fine i also bought a new lpg vaporizer and didn’t fix the problem. Sonit cranks no start. any idea what it could be Thank you 🙏🏼
Did you check if you are getting lpg out of the injector? This system uses a throttle body injector. To see if you are looaing fuel spray a bit of brake cleaner into the intake tube while cranking and see if it starts, if it does you are loosing fuel.
Very technical, that's how you know you know what you are doing. Genius! I'm not technical at all but I figure them out. Btw. Your tech needs training, that's basic stuff. Lol. Just a FYI a warmed up k21 or k25 will run with 1 cylinder.
Ok...so if asked ...what caused the cylinders to loose their compression...i saw that you adjusted out the pushrods...but what caused this situation...I could see the adjusters getting loose and backing off ...but not tightening themselves up ...???
As this is a truck that was sent in by one of our field techs, I did not have any history about this truck other than what the tech told me. I also believe that this is not a natural phenomenon(or at least I've never seen then tighten by themselves). My best guess is someone tried to play mechanic when it started running poorly and misadjuated the valve clearance.
Nice job. I'm starting as a forklift road service tech in a couple weeks. Is a Picoscope an essential tool in this field? I know there's other ways to get to the same solution And I know how expensive one is!
It would be very helpful to have an oscilloscope. Like you said there are other ways of arriving at the same conclusion, it's just takes less time when using a scope in my opinion. Today's forklifts have more electronics and relies on sensors that are too fast for a basic multimeter.
As a road tech 2 basic tools Id never be without are a good decent multimeter, Fluke or Martindale etc ( not cheap Chinese crap ) and my PowerProbe.....my 2 best friends!! 😁😁👍👍🇬🇧 Best of Luck ☘
What are the average pays for road techs in your guy's area? Just curious and there's a good chance everyone here is from different states. I'll start, here in Ca. average roady makes $30 up to $45 hr.... forklift geek would be considered top tier with his technical skills with that scope.
@@MaintenanceMan00 good luck bud. It's a lot easier on the road you get a lot of down time. Hopefully they'll pay you for your drive time as well. ....and as far as tools if you do a lot of electric lifts you'll definitely need a fluke meter and for LP's a power probe will come handy as well. Oh and get yourself a set of 4 way angle wrenches for them hydraulic lines trust me on that one.
So I'm currently working on the Mitsubishi fg25n with this same k21. Initially had the E-43 code when I acquired the project and is currently a crank no start exactly like this. Itll pop over on starting fluid. And it seems to have fuel up to the primary injector. Is there a good way to test the injector? I'm basically new with this lpg stuff.
@@forkliftgeek10 I'll have a look at her again today and see if that can be done. It seems like the primary injector is bolted to th intake where the lp line is ran. Maybe a guy can see lp with the intake horn off?
@@gnarlytaco6604 you can take the injector holder out with the injectors by taking out the four bolts that fasten it to the throttle body. When cranking the injector would start to spray lpg.
@@forkliftgeek10 I'll give it a shot in about an hour or so. I'll let you know the result. I appreciate your help with this. There is little to no support for this unit out on the west coast.
Hello any chance you could help me with my Toyota Forklift 4y Engine I am having a problem I just replace my distributor today I got a new distributor from forklift World no I’m having a problem on the two wires that run to the distributor the negative side I’m not getting no negative and and my fuel pump I’m not getting no positive what could cost this problem
Ok. The ground for the distributor is through the body of the distributor. The other wire into it is not a ground but a signal wire to the rev switch which controls the lpg relay. The positive to the fuel system only goes through the fuse then to the select switch. Make sure the switch is flipped to use gasoline and not lpg.
@@bobbydavis8776 unplug the o2 sensor, if you still only get E25, E26 and E43 and no other codes you know your in the right ball park and can test the sensor....also check the ECM under the battery, prone for dirty corroded terminals, poor grounds and some failures where the wiring terminates in sensor connections etc.....once youve changed whatevers at fault youll need a tech with a laptop or do the " Cat / Mitsi pedal dance "!! 👍
Great video. Thanks for sharing
My no start issue was a bad lpg injector,, especially in cold weather,,,heated it up with heat gun , crank every time,, nice vid
Sir
Yale forklift 5 ton engine cranked but not starting
Thanks for sharing knowledge
What program are you using I use uptime catdozer and truck tool

Great job and so inspiring to look at your vids + you learn. When the engine clicking is that almost always the valves? And why the clicking sound?
The clicking sound is because there is too much clearance between the rocker and the valve.
@@forkliftgeek10 Ok thanks been thinkin of that for a while why it happen? :)
What scope are you using?
Picoscope
Can u check the cam and crank phase without an oscilloscope
Without a scope the only way to check cama.nd crank.timing is by visual inspection of the timing marks.
You live up to your name. I've been assembling Nissan forklifts for 9 years now and you could probably teach me a thing or two.

Can you tell me the lash clearances on a G424E?
I think that engine has auto lash adjusters
@@forkliftgeek10 Hate to hear that. I'm running out of ideas!@
Good job
What is that program you are using on the laptop?
Picoscope
Nice 🤟

You could take it out of the holder and see if it shoots out lpg.

Hello any chance you could help me with my Toyota Forklift 4y Engine I am having a problem I just replace my distributor today I got a new distributor from forklift World no I’m having a problem on the two wires that run to the distributor the negative side I’m not getting no negative and and my fuel pump I’m not getting no positive what could cost this problem
After placed in the distributor it was running fine for half off today
When you say fuel pump, you mean this truck is gasoline? You did not say what model you are working and different models use the same 4y engine.
It could do both gasoline on propane but I have it on gasoline
Ok. The ground for the distributor is through the body of the distributor. The other wire into it is not a ground but a signal wire to the rev switch which controls the lpg relay. The positive to the fuel system only goes through the fuse then to the select switch. Make sure the switch is flipped to use gasoline and not lpg.
The model is 7fgu25
Will run with one cylinder
Hello by chance you help tech over the phone thanks
What problem are you having?
