Just watched your video and I have to say thank you for a video well done! I had a no start issue with my jurassic period Allis Chalmers. I had done a lot of what you showed already, but not the brake fluid into the carb trick, that is simple but effective. In the end what I did is clean the regulator and carb inside and out very well, propane lines too. Fired right up and got rid of my stress issues too! Thank YOU!!

[@StanFlahautAFD]

It was brake cleaner not brake fluid.  You have to be sure it is the flammable type too. If you use the CFC kind it doesn't work. Use starter fluid and be sure to stay away from the throttle body when you start it in case of flames from a back fire.

[@twotone87200288]

hey buddy, thank you for sharing. I actually was working on this same lpg regulator at work the other day. The issue I had with this particular one was with the diaphragm. apparently after awhile, the oil they put into the propane to give it its smell can clog up and keep the diaphragm from working properly.

[@carlosmafla9177]

Andy Freeman Haha same happened to me like two weeks ago

[@andyfreeman660]

the first thing to look at before you get any tools out on a duel fuel Toyota, is the truck switched to LPG if it's switched the GAS (petrol) it will crank but not start. you would be amazed how many people get cought out on this one ( myself included)

[@AndrewSmith-pp6ir]

And the switch gets bumped half way between gas and lpg sometimes which gives no start either

Unfortunately, price of solenoid was more than half the price of the regulator. So might as well replace the whole thing. But still up to the customer if he wants just the solenoid. In this case he opted for the regulator.

[@travisjohnson2753]

Thankyou! This will make me a hero at the shop!

+Travis Johnson when you're spraying brake cleaner into the intake always have a fire extinguisher on hand as it may backfire. Something that I should have said in the video. Thanks for watching and always be safe.

[@gigglegasn20]

That's a very common problem on Toyota forklifts, usually I would just put my hand on the solenoid and crank it and you will feel it if it works. If you're not getting power to that connector it's most like the relay located under the fuse box.

[@micheldupras7854]

Hi Jay, what if the test light doesn't light up when you check the power going to the solenoid on that connector when cranking? Bad wiring?

[@forkliftgeek10]

Bad relay, wiring, fuse or rev switch on positive side. If this was a dual fuel check if the switch is flicked to gasoline.

Did you replace the regulator or just the selenoid only? I thought just the selenoid was suspect?

[@johnblack4636]

Good job bro and thanks for the video;-)

[@andyfreeman660]

depending on the Gas regulator type the slow run solinoid is powered from a sensor in the distributor. if you have high gas flow to the carb ( mixer) the engine will crank but not start and the main valve seal inside the regulator.

[@forkliftgeek10]

+Andy Freeman the type of regulator would depend on the model of the forklift. the regulator you are referring to would be more likely in an 8 series. As far as high gas flow, yes it would produce the same symptom but exhaust would smell of unburned propane and adding external fuel source would not get the engine to start.

[@JW-qd4ig]

Hey forklift geek, Thank you for the fun interesting videos. I appreciate solid diagnostic work. And the explanation is spot on. I have a toyota 7fgcu15 with a no start, I diagnosed it to a (what I thought was a faulty shutoff solenoid) but rather a no power to the shut off solenoid issue. Do you know what else is on that circuit? It powers the solenoid through the ignition switch, but without a schematic I do not know where the solenoid connecting wires come from. Thank you

[@forkliftgeek10]

kzbin.info/www/bejne/mITZgKNjr7efg7M This one is a 7 series, but not all 7 series are wired this way. Some of them, the lock off is powered by a rev switch and the input is from the distributor.

[@JW-qd4ig]

@forkliftgeek10 I just watched that linked video. I will definitely look into that. I bypassed the main solenoid (in the regulator) to feed it voltage so it would open. Then that is when I discovered it would run, but this video could definitely be the final culprit or at least similar to the problem that I am having. Thank you again for the explanation.

Hello، my forklift don't start and hydraulic system not work also i Do not have current to my starter relay and when i took wire direct from positive battery to positive relay it's start but hydraulic system don't work. Can you help me please

[@WarrenStarCat]

This is good info, but we are dealing with a newer generation Regulator with dual solenoid lockouts. Getting an intemittent, NO START after the rig sits for a while. Same as yours it will try to run with starting fluid. Also breaking the flare connection coming out of the big lockout solenoid path, bleeding off some pressure and re-tightening may allow it to start. The Attending Forklift is also Puzzled by this one. S/N is 41051 Model 8FGU25. Any suggestions are helpful. Star

[@forkliftgeek10]

Sometimes the main solenoid (big one in the middle) gets stuck or the solenoid is already weak. When it is not starting try tapping on the solenoid and see if it starts.

[@WarrenStarCat]

@@forkliftgeek10 Thanks for the info. 10-4

[@WarrenStarCat]

OK Excellent. Tap on the secondary lockout on the REG when cranking and it start right up after prolonged NO START. Good Technique. Thanks. New Reg should solve this one.

[@mattsan70]

I'm confused - you didn't show that the solenoid was getting a good ground to operate it - just +12v on both sides of the coil. to me that suggests a relay up stream is faulty more than anything on the regulator

[@forkliftgeek10]

Yes I did. At 4:58 in the video, my test light is clamped to the battery positive so when it is lit from the connector it means I have a good negative. Transferring my t pin to the other side of the connector and have the test light lit verifies that my coil is not open.

[@scubastevesdestiny]

Hey there. I have a tusk forklift. It is made by Komatsu. I just purchased it this morning and drove it on the trailer as well as off the trailer. While backing it off the trailer it hit the ground pretty hard and I drove it into the shop. I shut it off and it never started back up after that. The guy mentioned he cleaned the regulator to get the machine back running again. I have to assume that somehow the regulator is failing. It seems to be forcing a enormous amount of propane into the system when I turn the key key on. It acts like it wants to start but it just won't do it. Do I need to replace the entire regulator? It's blowing the excess propane out of a small vacuum size line off the side of the regulator that goes to the intake tube.

[@forkliftgeek10]

You could try the rebuild kit

[@jesuszaragoza6554]

Hey if the truck didn’t start with brake clean, what would be you next step?

[@rodneyleboeuf164]

If it didn’t start with break cleaner then that would suggest a ‘no spark’ problem. Such as spark plug problem, ignition problem, coil problem.

Hi, how much does solenoid costs in average range?

[@andycarpenter5561]

@forkliftgeek I'm having a minor issue with my Mitsubishi propane forklift. Seems lately I have to stomp the gas pedal to the floor to get it to start. Could that also be the solenoid or should i look at injectors?

Your mitsubishi would have a different fuel system than a toyota.

[@FleetTech97]

Hey man I have a Toyota. I sprayed starter fluid inside and it just cranks and tries to start but never catches. It’s got spark but it looks a little weak. Could it be the distributor cap? It’s got new plugs in it. What should I look fir on the cap ?

[@forkliftgeek10]

Worn contacts in the cap. The cap is not the only part that produce a weak spark though. The rotor, ignition coil, ignition module, and cables are all suspect.

I personally like to convert over to the Impco fuel system if the customer wants to replace the Aisan system from the factory. They run better with less problems and are cheaper to replace in the future.

I have a cat gc18 no start, LPG i have changed the vaporizer and the lockoff, I also changed the oil pressure switch and I have 9 volts to the lockoff and no start, if I jump over voltage directly to lockoff the forklift starts and runs a few times, I also had battery checked by Napa and swapped starter with new and no fix, any ideas?

[@solden49]

So I have a propane floor buffer that is doing the exact same thing. It was running perfect until I dis connected the hose from the vaporizer to the carb and turned the propane valve on. I put the hose back on and now and it still will not start. I have bought a new vaporizer and solenoid and it will not start. Any ideas if that made sense?

Great Job, I have one 5fgcu20, gets spark with key start, has good compression, cap, wires double checked, will only stumble on start, fuel is controlled by vacuum only on this one, big clue is it wont run with starting fluid in air intake. does this sould like distributor or exciter/coil, I got this job to help these guys out and got it started by jumping the relay the guy before me cut the neutral saftey switch out of the harness, so i was lost with wires dangling and off the start relay, figured most of it out without schematic, got it to start with jumper to relay, started everytime one pop, so i fixed the hydralic cylinder for side shift, installed new key switch, repaired altenator lower mount bolt broken in cover, hood hinges repaired, rewired as best i could they way it was running and now it won't start only stumbling with fuel open, Any Idea?

[@forkliftgeek10]

+Gary Castle pull out the hose from the regulator to the mixer. When cranking the engine there should be no gas coming out, if there is then it's flooding the engine. You could also check the butterfly on the governor, I've seen it before that when the engine vacuum increases it pulls it shut due to a broken spring. Ignition wise I usually use an ignition tester and set it to 30kv. If it's not able to jump that gap then I'd check for high resistance in the secondary circuit.

[@garycastle1477]

thanks for reply, good thing to look at, I checked the two units out the bottom unit looked new and shinny, had small amount of black dust inside that side, the upper had some waxy stuff but not clogging anything and the vacuum seemed to activate the switch to open valve to let LPg thru. The broken spring you mention is that in the upper or lower unit of this regulator mixer ? I have gotten spark from plug but its a very small bluish white spark that is not that strong cause the shock wasn't that bad! The plug wire 4 is bad and is getting replaced asap, but others were ok and stronger. Would that spring stop it from running on starter fluid? This is why I think its ign. THANKS FOR REPLYING. Really Appreciate it. Gary

[@forkliftgeek10]

Top unit u are referring to is the lock off and the bottom unit is the regulator. The mixer is on top of the intake manifold. On the mixer side (carburator) there is another butterfly which is spring loaded. Shoot me your email so I can send some diagrams.

The forklift uses gas only

[@forkliftgeek10]

A no start, would always fall into 5 possible causes. Fuel, air, compression, spark and timing. In your case it would more likely be fuel related. I would start with figuring out what and how fuel is provided during cranking.

I’m desperate for help. I recently purchase a Toyota 42-4FGC25 lpg forklift. I purchased it at an auction and it ran perfectly fine. I transported it my shop and I can’t get it to start. It has spark. The forklift was at sea level and I’m now at 4700’ elevation. I’m assuming I have a fuel mixture problem.

Any help would be greatly appreciated. I purchased a new battery so it should have plenty of voltage. Thank you.

[@honi9]

wondering if you can help? I have a forklift which is a Henley husky 12 which has a ford 4cyl 2711e convert with a beam 120a propane system. The problem I have is that the forklift runs fine when shescold and just been fired up, though when she gets hot after say 10mins she begins to struggle to rev properly like she is struggling to get fuel. you can put full throttle and she just sits all lumpy at idle revs struggling to do anything. then out of the blue she will pull through and rev normal for a few secs and then die off again. if I let her cool down for 15mins she will fire up again as normal until she gets warm and then do the same thing again. bare in mind shes an old girl so the engine runs a little hot anyway so im wondering if its too much heat causing this as the regulator we have the beam 120a is so hot that you can barely touch it... Im wondering what you can advise?

[@forkliftgeek10]

+honi9 when it's acting up you could try what I did here and spray some carb cleaner or brake clean into the intake and see it runs any better, if it does then you are probably right that it's lacking fuel. Be careful though in using an external fuel source as it might backfire and if you sprayed too much into the intake it might catch fire.

[@forkliftgeek10]

+honi9 does the regulator have a primer button? Sorry not familiar with beam regulators.

[@honi9]

ForkliftGeek why is it only doing this when the thing warms up after 10mins running though. plus why is the regulator/mixer (beam120a) so bloody hot to touch?surely the coolant feed into themixer shouldn't heat it that much? could that be the problem? is it getting so hot the diaphragm is going all to shit with the heat. then when its cool the diaphragm is fine again? this is about the level of my grasp on the situation...

Good day Sir, about the positive side of that solenoid,,why is it blinking when cranking, is it the engine timing? What if theres nothing on positive side,what some alternative ways to test or check? Salamat po:

[@forkliftgeek10]

The blinking is the voltage fluctuation from the battery. Whenever a load is applied to the battery(in this case the starter) the voltage drops. If there is no positive supply you could do a bypass test and provide your own 12v supply.

Hello Sir I have a problem with toyota 8FGU25. The engine fail and the aceleration is up nd down every time, I can see two error code E-03-1 and E-01-3, Please help me to solve this problem.

[@forkliftgeek10]

E03-1 is an intake pipe pressure sensor open. Check your connections on the map sensor. E01-3 is a rich condition. Go with the E03-1 first. Check also for a vacuum leak.

The engine has to rotate fort the solniod to pull in

[@tobybrewer2439]

Got a s50ft no fuel new regulator getting fuel to the solenoid but not past would that be the problem

[@forkliftgeek10]

Make sure the solenoid is getting power and ground

[@tobybrewer2439]

You the man broken ground wire thanx so much

[@SergioCruz-ji3jy]

I'm having the same problem but with a Nissan it cranks but won't start any ideas what it could be?

[@forkliftgeek10]

If it cranks with normal speed then one or more of the following would be missing. Spark, fuel, compression, air (being sucked in). If all of these are present then it would be timing( ignition or cam/crank).

[@MrSfbsnyder]

if you have spark and no error codes, lp regulator is over pressurizing

[@ayerimosfox]

Will this solution also work for a conversion kit for automobile use?

[@forkliftgeek10]

As far as testing if you are having a fuel problem, yes.

[@danieloriaku6624]

I suppose so, since it's all based on the same principle.

[@albertososa5791]

What about when you have changed the entire regulator but the forklift wont start

[@forkliftgeek10]

Cranking no starts would have 5 possible causes fuel, air, compression, timing and spark. If it was fuel related, it either is lacking in fuel ir in excess. The regulator is only one part if the system. The mixer is also a possible cause and injectors(if it is equipped).

[@albertososa5791]

@@forkliftgeek10 ok but we spray starter fluid on the air filter are and it starts no problem but when we turn it of and try to start it up again it won't we have to spray it again to start it

[@forkliftgeek10]

Then I would suspect a vacuum leak. Other possibility would be a broken hose from the regulator to mixer or mixer to lock off.

Where can i go to school to learn forklift repair?

[@forkliftgeek10]

If you are in Canada, you need to be employed as an apprentice first before being accepted into school. Don't know about other countries though.

[@busfairnitrometh]

Im working on a 8series Toyota forklift with a code e 09-1 and will not start. Any ideas

[@forkliftgeek10]

+busfairnitrometh 09-1 is ignition signal abnormality. No spark?

[@joepacheco4038]

Broken wire tach sensor

[@1176hambone]

All of that just to find out that the whole damn regulator needs replacing? No shit.

[@muhammadattique6230]

Good 👍
