You forgot to say "New battery from NAPA, not a sponsor." Oops, sorry wrong channel.

Indoors, out of the wind and weather? SWEET!!

that ecu is A PRIME candidate for dry solder joints

Thanks for the memories. That lift has 1980's GM code system. The words "Flash code 12" triggered flashbacks to when a bent paperclip was my goto scanner 😆.

When I used to work on aerial equipment we called those scissor lifts SKYJUNK

Back when I worked on construction equipment, all of it was old and worn out with things disconnected and jumpers around circuits. This was back before easy to access info found on the net. Giant PITA. Shuts off after 10 min, first I would check for a strong spark, a bad coil could short out and do this.

It needs some serious maintenance due to lack of years of maintenance. Lots of obvious items are neglected which indicates owner doesn't keep up on repairs etc. Wiring and ignition issues.

Went through the same diagnosing for the same problem on the same machine. All the same thought process and testing… bad ecu was the culprit. Thanks for the memories lol.

Thanks for sharing, I always learn something from your videos.

At this stage, would have 3 sticks of dynamite on hand, and politely told Bob to take cover. Would not apologise for my actions and would put it down to normal practice in extreme circumstances. A man's got to do, what a man's got to do. No codes and then what ? Try the fuel tank for gas ? Crusties on board, perhaps? Faulty coil ? The list is endless. Have a coffee break and clear the head. I'm under pressure and not even near the machine.

That is one mad system, i would strip the plugs going into the computer and see if there was any nastys. Also do the plugs stay in fully, a couple of cable ties round the computer to keep them from jiggling about. Oh and i would run away fast, i mean really fast :-D

Another day, another scissor lift with vague symptoms... this should be fun.

Corrosion in outdoor terminals will eventually give you problems...Clean ALL connections with Deoxit and then put dielectric grease to encapsulate the pins/connections...I have fixed countless problems this way...

Wow, Ivan. Nissan scissor lift??? Dang. Man i gotta wait for the conclusion!!! Lol. Great diagnosis! Many thumbs up!

I've seen a plastic bag in a fuel tank cause these periodic issues; when the engine runs, the pump sucks the bag around the pickup; when it cuts off, the bag falls off the intake, and it will crank again, Conventional fuel filters can also do this. I had to skim through this video, so I assume this is not one of those sky lifts with two new 12 volt batteries that some bright light connected the wrong way, so that the one battery you charged up is essentially neutralized by the recharging of the system after 10 minutes and the low voltage cuts off the system.

Zenith, the quality goes in before the name goes on.

Как здорово, что можно отыскать документацию на все, что ты ремонтируешь! Работа, превращается в удовольствие...

Ivan performs magic using science and logic!

I'd look for the shutdown timer.

Hopefully the ignition coil wasn't weakened being disconnected while cranking. Also with the weather seal not mating correctly could cause moisture and corrosion to find its way into the ECM. Have to wonder if the tie wrap was really there to compensate for another issue within the module harness connection. And tighten that alt belt!

I have been seeing your videos but today I have subscribe great videos keep them coming

Hell if you ain't becoming the master of the MEWP.

For the fuel pump, I'd check those taped up repairs on the control box cable, where the scissors had cut it.

Ivan I will wait for bonus footage LOL 😀

Go get em young man!!!!!! Wooiooohiooooo!!!!!!!

I remember counting the flashes, that's some old-school stuff, try disconnecting the battery and doing an ECM memory clear by grounding 203, if that doesn't work go to lunch and don't go back 😀

you can use silicone spray on those weatherpack seals. works wonders.

One thing Ivan's job will never be, routine and boring.

I can offer an explanation of the 10 minute limit of continuous operation. The appliance is a sky lift, and with gasoline operation (in Australia, something outlawed for use in enclosed spaces, due to CO emissions). It most likely has a time limit set on the ECM, for adequate dispersion of toxic gases (mainly carbon monoxide) with only a short time of operation (much less than 10 minutes) necessary to ascend/descend...

Reminds me of reading DTCs on my 86 Crown Vic with EEC IV. Have to use an analog voltmeter and count needle swings. My wife's 89 Probe with MECS II is more advanced -- just have to count flashes of the MIL. People with OBD II don't know how good they have it.

Hey Ivan, My guess...possibly a bad computer Gnd....gets worse as engine warms up, and rough crank ups might be all related? Other possibles: Faulty MAP sensor, or it's connections..(could cause rich, or lean, or all over the shop) Ignition system related...(could cause rough run, and da black smoking) saw one good spark, but you had to get a lot closer to the coil with your test light to get a spark after that? Faulty Throttle Actuator....or loose throttle plate...Perhaps the last screw finally came detached from the throttle shaft and the butterfly has shut off the intake completely?...No more rattles now, but might explain the erratic throttle behaviour prior to a complete shut down🤣 Hard one when almost all symptoms match the possibilities....can't wait for Part2..lol🤣👍🇦🇺

Don’t ya just love them jobs that seem to want you to stick around a while Ivan? That blinking check engine light reminds me a lot of them gm cars back in the nineties. Even has a throttle body injector.

Nice !

Very nice video, thank you. Find the missing wire for the temp. sensor.

I can't understand almost every car you are solving problems on has corroded terminals. It almost every time tells me "lack of maintainance". My cars never have corroded terminals, always clean and protected with Petroleum Jelly. For capacity checks i use a simple capacity tester which give me the CCA and voltage and health of the battery.

liquid cooled/heated throttle body assembly, on propane in winter would likely ice up bad. looks to me the ECM coolant temp sensor is actually the one on top of TBI @ 15:13 while I suppose it could be air temp, I don't think anything that age had them. BAH I had the sensors flip flopped, I seen the lower one, but though oil pressure earlier in video, after seeing closer view it was clearly temp sensor body

My guess is when you installed the new battery you jiggled some wire to the fuel pump

Looks like you're getting a rep as a scissor lift whisperer. With this flakiness I'm going with the dry solder joint(s) in the ECU comment.

Sounds like a 2 stroke motor cycle.

That thing runs like an engine in a Bugs Bunny cartoon...😃

Welcome to good old fashioned OBD 1... counting flashes...

Man. Those things are a nightmare of wires and safety’s. I’d check for high temp or low oil pressure. See if it has a time out timer?? May be a safety issue of idling for a long period? Trial lawyers love those things...

Another cliffhanger, soooo cruel

15 lbs at fuel pump sounds low.

I would re check for spark and fuel supply while its not running, maybe a squirt inn air intake, i have know an ignition coil to get hot and pack up...F

Good

those are standard GM OBD1 codes. 14 is coolant temp sensor and as you say 33 is MAF/MAP.

If you plan on any trips through Ohio in the future, lmk. I've got a funky misfire that might be fun to diagnose for a video. Thanks Ivan!

Take a close look at the pins and socket? might be something jammed in there, keeping it from full contact.

Like #617 Thanks for the video!

If this engine has a ceramic resistor connected to the coil, then that might be the issue. May have to change out both the coil and the resistor (if it has one).

There’s a real reason they’re nicknamed “SkyJunk” in the Australian EWP rental market

Had same problem with a jeep , firewall connection was bad.

quick shut down sounds like ignition

Ivan never met a scissor lift he didn't love. ;)

Yeah other people have mentioned the ecu dry joints, why would a manufacturer fit an ecu above and on top of an engine just doesn’t seem like a smart place to put it to me. Don’t know if it has a crank position sensor I have known them to fail when they get hot and not set a code...

I haven't seen anything made by zenith in 30 years!

Wow, I am only new to your Chanel, I like the content, but did you put in the 10 adds or was that google because you left it on automatic for mid roll adds. If they are all like this I will reconsider my subscription.

I'm saying maybe a ground issue, maybe a circuit board issue. Something that fails with heat, resistance goes up when heat goes up.

Ivan, you should call Zak Bagans.

When the fuel pump primes I heard a relay click .. when not, I didn’t ...

The fueling throttle body dose have problems in this thing.Should of be cleaning it out and checking fuel source coming in and make sure all the sensors works?Should getting this thing working again.

So anyhoo. My westbound problem is fixed. It seems as if I was missing a tire valve stem cap on the left rear. This thing drives like a new car now. My radio still only plays crappy music though. It's a Delco AM and I never hear any Billie Eyelash or Machismo Kelly. Pretty much just this really long song that goes SCRSSH. I have heard that if I smoke more meth it gets better. I went to the dealership and they called the cops. Does Dorman make a decent meth deal? I have a broken light bulb to smoke it out of. I lost the factory meth pipe in a BLM riot when I was rolling a flaming dumpster at the courthouse. It's a whole deal man. My mom even freakin' threw away my Animals on the Farm coloring book. I didn't even get to do the cow! What's up with that?

Throw a set of spark plugs at it. Is the exhaust leak messing with the O2 sensor?

Heh heh heh!!! You always get a bad feeling when there's a dozen zip ties holding it together....

You broked it...lol

I'd guess that front sensor is a coolant sensor, but single wire for dash gauge, not ECM, it would be elsewhere and either two or three wire(probably two wire) since that engine has separate gauge sensor. trying to recall back to the age range of that dinosaur engine design

If it goes out in 10 minutes I believe it has something to do with an electronic component because of the heating, I would see the coil and injector next.

When are you going to titen the alt belt

May be a highly sulphates, battery a lot of surface voltage only quarter.of batt capacity.

Dead cell, ECU won't come on with low volt so engine won't run. Tale Tell sign is the low volt and the fan comes on. Its a default on Nissans I think.

Call Keith.

23:00 Ivan, that is the original coolant sensor on a Nissan A-series engine. please share the displacement, I am really curious.

A thermoswitch on the coolant sensor ?

That Alternator Belt should of been addressed early on.

This is nearly the same as my '88 Nissan Pulsar NX (videos on my channel) It's ECM was Pre-OBD1. Engine warm, it had a dashpot, you turned it to "DIAG" and it had 2 LED, green =1 and red= 10. These codes are in a Haynes '88 Nissan Sentra manual, and also here-------> www.apexautoaz.com/nissan-obd-i-codes-.html

Fuel pump

Is the low oil sensor possibly causing the shutoff ?

Need an Identifix for construction equipment!

This is OBD1 codes

with no trouble codes stored after engine died.. I'm going with the coil. (et al)

check the coil

sounds like ignition or fuel misfire, bad grounds or ecm issue maybe

Did you check the oil an cooler levels?

Check oil pressure sensor

Same battery that was in it when we bought it who knows how many years ago. What is it about construction companies?

I would give it a service & see how it runs then.

Go back and checkout throttle body after that 10 min stall?

amp clamp unavailable at link?

Just sayin... You'll always be "That Guy" somebody might call, instead of a shop or a dealer for stuff ....... lulz....:o

Got a question Runs like its missing and oddly eill rev up. But not sure.

Ivan, what engine is that? looks like A-series. Do you know?

It was clearly code 12, code 14 and code 33.

Never knew Nissan made them that sounds like a Nissan car engine

MAP sensor over voltage. Edit: Ah, you found it at 32:50. I commented when I "diagnosed" it as the video is playing. Lol

After 4 minutes, I'm calling it the battery. That's my story and I'm sticking to it.

fuel injector shorted windings

Do you not use your new Fluke amp meter anymore?

So no low volt

Spray all pins and check also check relays. Why only 15PSI with an injector that can't be right. OBD1 is very minimal doesn't show but 30-40 codes if that on this machine maybe 20. You may have low voltage again, oil pressure, bad coil after heats up and short internal, go back to basics when stopped.
