- This one was definitely EPIC.
2002 Jeep Grand Cherokee 4.0L inline 6.
Crank no-start with major parts cannon damage, including an engine rebuild.
Owner is ready to give up, and towed it here from over 5 hours away.
Dealerships told him to POUND SAND!
Let's see if we can get it running without too many more parts or sweat :)

I would've taken one look and said, "the dealer was right, the nearest junkyard is..."
The dealer was looking at how much they would be charging the customer to get it running vs. asking the customer if they wanted to spend that kind of money and calling it a no sale.
Agree. The tech probably popped the hood and saw how much it had been messed with and said nope.
@@Garth2011 yeah, why waste his time.
"P00099: push it into a river and call it the day"
Rip that tired old six out and do a clean LS swap
People want to get there vehicles to you because your honest and you know what your doing.
*their
*you're
And nobody else that knows what they're doing will work on them.
Brakes, breaks, your, you're, they're, there, their, bare, bear....etc. it blows my mind how horrible people are at knowing the difference.
@@HouseCallAutoRepair I know!! I’m a former teacher and it drives me absolutely crazy!! I’m not trying to give anyone a hard time, just provide corrections. But it’s amazing how defensive some folks get when you point out their mistakes. As if it’s a personal attack!!
@@HouseCallAutoRepair Maybe people don't have the same education as you, just be fortunate you know the difference.
By the sound I was waiting for a rod to come through the side. LOL
I truly thought the same. The audio through the camera can play some harsh tricks 😁😬😅
I just started my 98 Jeep just before i watched it...mine is purring so nice...could tell by the cranking it was not right...too slow...either a dead/weak battery...or a starter starting to die and dragging / bearings/bushings etc...sticking or timing issue....or it seized and was sticking on rings !! 😆
After it started it was obvious it needed major help....
Think the owner touches too much and not enough knowledge of what to do...🤔
Yeah same here.
Even the legendary 4.0 needs proper TLC.
You brought that one back from the dead!
he doesnt know how big of a favor the dealer did for him...
Yes and I think there's a lot more that owner doesn't know.
A few years ago my 1998 Jeep Grand Cherokee died while driving. Then it just cranked but wouldn't start. I had it towed to my mechanic and he had it diagnosed in 5 minutes. Yep, you guessed it - a bad Crankshaft Position Sensor.
Nice, I had a 2004 Jeep Grand Cherokee with a very similar problem it took me months to figure out it was the crankshaft sensor instead of the camshaft sensor. Mechanics like you sir are worth your weight in gold.
Yeah a scope can cut that diagnostic time from months to minutes 😁😉
@@PineHollowAutoDiagnostics I just wish I could find a mechanic who knew how to use a "scope" as you call it. Its nearly impossible to find someone in this area who will diagnose electronic/intermittent electrical problems. Like that job how many hours did you bill out for it if you don't mind me asking? If it was 10 or less its well worth the cost.
Another epic Ivanalysis!! There was a crank signal, but it was dirty, nasty and wrong. A Vantage Pro would have worked. A Verus would b better, but the Pico ruled the day. The proper order in establishing the fundamentals was the ticket. That gearshift cable adjustment could have led to some real excitement. Chasing the Jeep down the driveway might have required one of the wife’s horses. Thanks for a great Sunday afternoon!!
Ivan is a awesome mechanic. You and Eric O make the best engines repair videos on TH-cam
They’re listed number one and number two in my subscription list for good reason. Totally agree!
Check out' Diagnostic Dan 'I believe he is one of the best for import vehicles BMW, VW etc.
@@alanmcclelland5245 yes he is very good too.
@@alanmcclelland5245 Scanner Danner is decent as well.
When I was a little less experienced, I had a similar low-compression sound on my chrysler 3.5 engine. After quite a bit of cranking and spraying starting fluid in it I stood outside the door and listened to the engine turn over. It had that fast crank sound with an occasional hesitation or ignition. I became convinced that the timing belt had failed, and I pulled the timing cover off (in 20 degree weather)... The timing was right on the money. Later I found a failed fuel pump fuse (with a hairline crack in the filament). The new fuse was all it needed. I had skipped some of the basics after hearing that cranking sound.
As an FYI, didn't see it mentioned. You can also access the CSP Sensor from within the vehicle. You remove the drivers side footwell heater outlet to gain access to the plates that the transmission and transfer case linkages run through. After unbolting the plates you have enough room to replace the CSPS. The plates should use a rubber style gasket/grommet, which shouldn't need to be replaced; as long as you are careful on removing the plates. You don't need to unhook the cables there is enough slack to allow you to push them to the side of the hole. Learned that trick after the CSPS failed on my own 02 WJ.
"He took it to the dealer, they looked under the hood and they pushed it right back out." Lol...I got tears running down my face. And no, you can't blame the dealer in this case. After seeing that rat nest of wires, I had to double check the title figuring it was another three part video. But no, you cut to the chase. Well done doctor.
Why is it this guy can diagnose and repair the problem but the dealer cant? Its not impossible. I think they dont have qualified people or in other words people who love this job as much as Ivan.
@@JasonSpiffy The dealers have to deal with this thing called insurance. And contrary to popular belief "just have them write on a liability form" doesn't magically waive it all away. Source: Am a tech at a dealer.
I used to repair aircraft, I had one customer who wanted a certificate of airworthiness. Ten minutes in, I stopped and told the boss I'm not working on that pos ever. I pointed out several unnerving discrepancies I had found. He agreed 👍
Good video,that's a good example of the parts canon missing every time,lol.
i don't even think hand grenades would count here, lol
Installing multiple future failures... haha.
I'm sure it didn't need those ecms and maybe even the timing job . I bet it was a bad crank sensor from the very beginning 🤣
The naive owner already shot a battle ship size cannon before Ivan’s repair 🤦🏽
Very well done Ivan! A man who works on the ground and in the rain is one of inspiration and dedication to others. Keep up the good work! 😊 👍
Self-employment will give that motivation!
asphalt temperatures in 104 degrees Ive done that and rain so thats nothing new. with the old knuckle busters rusted bolts nuts. never comes out really greasy from working on vehicles..hes a softy. LOL
Excellent save Ivan, the owner must really like that Jeep, all he went through, turned away from the dealership! you know it's bad when the dealership says sorry can't help you, granted it had a couple of problems and the definitely hacked wiring but there's aftermarket support for that, great job
Dealerships like work that's easy and expensive.
Crank sensors cause all kinds of issues on these Jeeps. I had one in the shop last week that had a shorted crank sensor that was keeping it from even cranking over and had the security light on. Unplugged the crank sensor and the light went out and it would crank over. It looked like it had made it rounds through multiple shops as well. It’s always a good feeling to call the customer to tell them you’ve fixed their car after they’ve had it at multiple shops with no resolution. They usually act shocked when you tell them you’ve found the problem. I always get the whole “really. Are you sure?” response. I just tell them absolutely we don’t guess around here.
I got a crank no start Jeep bad cam sensor I got a cam sensor I put it in there was a little retarded I thought I was off a couple teeth so I turned it in I went the wrong way the cutout when is top Dead center which way is the shutter open front or back to the I know you saddling up to the is that both sides point for the her pointing to the front help me please
I don’t have any check engine light on and all my monitors showing green on my obd2 code reader but sometimes it cracks but wont start unless I put some starter fluid and then it will start 🤔
😂 foreal I know that feeling all to well
Excellent diagnostic work. The customer made a good call bringing his vehicle to you!
4.0l(242ci) and it's predecessors 232ci and the 258ci, are quite possibly the best engines ever built!
No offense to the owner, he may want to leave the auto repair to the pros. Ivan is one of them along with Eric O. From SMA. :) Good job Ivan
Thanks for the kind words Tracy!
There are a couple good ones out there. All on the east coast it seems. Bummer for me but probably good for them. Lol I'd be finding the toughest cases just for them to make an episode on.
Great job !! Your understanding of internal combustion engines is the key. Your knowledge of electronics allows you to complete the job.
First thing I thought when I saw that hack job was "boy am I glad my 4.0 is a 97 and doesn't have that camshaft sensor or coil packs"
Keith did a video on his channel a while back, on a Caravan. Crank sensor was timing off the flywheel. The fly wheel was broken. Couldn't tell until he looked at it with a scope. That was the day I decided I was going to get a Pico. I am glad I do have a Pico now. People will try anything when they are frustrated, but what they need is the right tool and the knowledge to use it. Heck I still don't own a bi-directional scan tool, except for my MDI2 for GM and my Ford VCM. A scope is more important to me the bidirectional controls for now.
I'm a die hard AMC straight six guy and am always interested in 4.0 stuff. when I see butchered wiring , especially with a Chrysler product, my head starts to pound. I totally understand why some shops will not touch it.
7:40 Did anyone catch that when cranked the rpm PID read zero, it should show cranking rpm. That means the CKP sensor is bad. I read automotive books and learn this things. I really like the videos like this also.
Tach moved a couple of times. Slightly at 1st then at end slightly more.
under ' ivan ' in the dictionary it just says fearless !!!
You're a magician, Ivan. When you listed all of changes that the owner / shade tree mechanic had made to this Jeep, I thought that you'd never be able to revive this corpse.
End photo looked like that iclan volcano; epic.
Ivan pulled another rabbit out of hat.
Don't know if around that time they still used round connectors in the quick plugs instead of flat bladed ones because round ones lose their tightness. Thats why your chasing ghosts like that. Almost have to smash the connectors and make them oval a bit so they have good contact again. Also use zipties so they don't rattle around.
If I remember correctly there are 13 tooth on the dist sproket so one should make a mark before disasembling the dist. Sometimes you start unplugging sensors and it will start. Assuming it is timed correctly, has fuel and the theft system is not on, it should start with just the cam and crank sensor. Replaced my cs with a standard auto product like 10 years ago and it's acting again. Must get real hot back there for cs to fail like that. Great work Ivan.
I lost track of how many cam and crank sensors i’ve put in these. If someone messes with it, usually makes it worse.
Yes talkin about losing track of how many Cam and crank sensors.01 Dodge 5.9 I returned all had saved got my money back at AutoZone. Of course that didn't help on my time wasted. I have now been purchasing Blue Streak or parent company standard motor ignition products. Hopefully I will have better luck. For instance distributor caps much better built. And most of all my old Chevrolet the distributor rotor Superior.
Ivan does it again. Very impressive diagnostic skills.
Thanks Carlos! PicoScope made it easy :)
@@PineHollowAutoDiagnostics YOU are the MAN!
Awesome case study Ivan. I can't believe you find such interesting projects.
Great diagnostic, Ivan! The best way to watch this edutainment is at the end of my day with a drink in my hand on my back deck. Who knew? Here's to you. Thanks!
Well Ivan, that was worth the trip. Glad to see things work out .
It wasn't raining; that was Scotty spitting all over the place about how the customer should have bought a Toyota.
To be fair scotty said those inline 6 run for ever
@@FerasAlhawas Not that in-line six... those jeeps are such terrible vehicles. The older ones may have been okay but the late model 4.0 is such trash.
I don't know how I missed this one. Since I own a Jeep Cherokee with the 4.0 in line six, I should have paid more attention. This was a great case study.
That was some fine diagnostic analysis. It goes to show how one problem can turn into a real big mess if you are not sure what you're doing. Glad to see it running again.
Sometimes it takes a few minutes for the lifters to pump up on an older car like that, especially with all the stuff that had been done to it. The old straight 6 motors generally run for a long time if you take care of them.
My hat is off to you sir. The amount of knowledge and patience you have a very admirable. Salute.
Great show I love it, as soon as you opened the hood and I saw the engine I said out loud CRANK sensor, it also helped me decide do to the fact that I own an 04 grand Cherokee with the same engine and have studied it completely top to bottom. Cheers from Jacksonville Florida 🌞
Great job! That's a beautiful area you live in Ivan.
So guy probably had faulty KPS and after engine rebuild still had faulty KPS!. Yip you can't beet the scope at the PCM to get a quick and accurate picture of whats what before the canon gets pulled out. Well done yet again Ivan, your some smart guy.
I’m with Bill Z! I was waiting for the rod to shoot from the side. 🤦🏽♂️ Great job and very detailed and to the point diagnosing. I know your customers are always happy you made time to fit them in bro! Can’t wait for the next weird problem you film for us lol
Another great diagnosis, thanks Ivan for sharing with us
You are an excellent mechanic. Smart as I've ever seen. Impressive, I needed you when my 1 ton Dodge cummins would not turn over. No clicks nothing.
Awesome skills you have there Ivan!!!
Well like Eric O says 'if I can do it, you can do it'. Well the guy gave it his best shot but after all he had done I'm not surprised that the Garages wouldn't take it. It takes a genius like Ivan to trace down the faults. But like I said, the guy did give it a go which is more than I am capable of so kudos for that. Nice fix Ivan. No disrespect to Mr O intended.
Good job Ivan, You are doing excellent work.
You really get into some nightmares! Great job.
Ivan loves a challenge. Great wiring mystery. Great job Ivan 👍
I've got another epic jeep case - Wrangler 4.0, after multipin connector hidden failure (second sutch case I know of) there have been quite a few serious specialists working on it, and after generous amounts of money spent on it a whole year later still no joy, lol. Yesterday I got it into my hands. Found out the ECU B-connector was assembled the wrong way around as a result of fault finding - no spark, no injector signal, no running and a lot of head scratching for many men, haha. This video is great, CMP/CKP oscillogram explained at the end of a video is exactly what I need without proper OBD equipment - my generic reader can't do much about timing settings of this car. Thanks!
Thats a good job. How about a contest with Eric O... whos customer has traveled the farthest to have their car repaired. I think at 7 hours, your're in the lead!
was mostly concerned about the HP laptop sitting on top of the potential Jeep fireball of an engine...
Eric had a guy from Canada stop by but I think that customer was judging passing by
@@arjungill6762 It's only 2 hours from Canada to SMA.
You have presented a very good t-shooting study. I'm grateful for the lesson.
the tachometer is something to keep an eye on when dealing with these problems sometimes they will show a bad sensor
I just got done with a suburban that the customer aborted with a engine swap from the wrong year 2007 to a 2000 but love watching you we all can learn from each other
Definitely an experienced mechanic like you knows what to look for using the right tools. 💯👍
There's no substitute for experience 💪💪
Wow that surprised me. Sounded really bad at first. Great job
Ivan thank you David from the UK I wish we could have seen the owners face now is running!!!!!
Having the same issue on my 93 XJ thanks for the much needed insight!
Man what a great exploration into why you need to scope your signals when you encounter a rats nest of issues that can be interrelated. Well done as always Ivan. Followed a similar protocol on a Range Rover Evoque I owned recently after a new cylinder head and valve job I did on it.
Great troubleshooting! Scope made all the difference.
"Sounds terrible but it runs" that's about all you can expect from a jeep
HEY NOW.
I can't believe you took that job! Hays off to you sir!
Thank you for the scope info we appreciate it very much Ivan!!! Would love to hear about settings of the scope in your videos! I watch everyone of them! You know like a baseline of parameters on individual sensors and testing. Thanks Ivan
Thanks Ivan
That cam sensor gap was deceiving. Well done Ivan. Thanks!
Excellent video Ivan you are truly scope man. Great job.
Ivan, your a blast to watch. Your flow always gets er done. ❤️
Beautiful background sound !! To the sound of nature
What a job to get to that sensor
Man, your videos are awesome!
Great videos mate please keep them coming 👍👍👏👏
Good one. Owner needs to change the oil after all that 😂
Ivan is an auto repair rockstar ,Great video
Absolutely fantastic! 👏🏻 I always enjoy watching your vids! You're completely spot on with your statement regarding scopes. They ARE NEEDED. May not always be the 1st tool, but so significant in this case. Just well done Ivan!
Oops! 😬🥴😅 Trans in reverse. Lol it happens! At least it was chocked 😁🤷🏻♀️
Gotta love the right foot tune-up! :-)
When your hack wiring job disgusts the Russian, you might need to improve your technique.
Hey some Russians have high standards for wiring haha
Where's a Russian
you are a monster man there's no problem you can fix
it like to watch you videos i learn a lot
Ivan, You are the best and when I need my next vehicle diagnosed, you will get the business. I only want you to do the work. Thanks for all the education. Sincerely, Jim
Apparently in Ivan’s world there are three levels of weird: weird, kinda weird and super weird. Makes perfect sense to me! 👍😂🔧🧰🚗
He only sees the weird ones, so a new scale is needed.
Garbage. Weird, kinda weird, super weird.... and over here.... no actually that's also bad. If you do this kind of diagnostic work, it does make absolute sense. The degree of weird can often point you in the right direction to the fault. Whether a signal is kinda there, there but choppy, not there at all leads to a different path in the sleuthing. Diagnostics of any kind is fun if you like puzzles and logic. But like anything takes some concerted effort and experience to become not a rookie.
Also... further in this vid "WooHoo - Holy Shit..." that's a common thing also. Fix one thing only to reveal another underlying issue. It's fun, but you have to be on the ball with "people skills" to deal with the customers - set expectations up front, never over promise. :)

Very nice! That poor Jeep is happier now. (Sounds like it took a while for the lifters to recover)
I cant believe that has that many miles on it and has not had the piston slap failure. Great video,
Ivan you did it again great job
Geesh Ivan, I didn't think you would pull this one off. Hadn't run for a long time, so long the gas was skunky. Geesh. Good one pard.
Nice work!! Oh boy I wish you lived here in Washington I'm battling with my Jeep rite now as well.
I had my 1996 Grand Cherokee straight six get flat bedded twice with crank no starts. Once a bad fuel pump, once a bad crank position sensor. Both with no prior warning signs.
Well done ivan, it's alive and kicking now :-D
What a horrible place to put a crank sensor.
One sensor problem would be bad enough, but two being wrong :-(.
13:20 my 97 grand native american will randomly pick up a cly 5 misfire (some times its a random multi miss + cly 5)
.
and im almost 100% sure its a 25% on its way out crank sensor
.
it seems to do it more often if i let it sit and idle...... AKA heat soaking that crank sensor
and i have only felt a SOFT miss a few times (98% if the time.... i get the CEL in the same spot on my trip....while at 70mph... and i cant tell their is an issue..... besides the CEL)
but ya..... a few times ive felt a miss at start up (old / worn spark plugs..... that + cap and rotar + new wires = cly 5 miss, when it wants to
.
.
fuel pressure is spot on..... motor runs like a top 99.5% of the time
but then i get these random CELs....... always for hole 5 or random multi miss
.
however.... even when CEL turns on (and after)...... motor runs like a top
.
only 126,000..... and i have records and the window sticker!
motor checks out fine on every test (fuel PSI.... compression.... leak down.... rocker shaft movement (aka not a bad cam or lifter or bent push rod)
its electrical!!!!!
.
.
but my scanner.... even at the shop.... is WAY slower to update than your fancy touch screen scanner
i was happy when our current could read ABS codes!
.
i could narrow it down to one corner.... VS the whole damn car......
.
.
.
.
some techs have it too easy
the amount of "vehicle specific issues" i remember is crazy
.
i have a hard time remembering im ~26
but can remember that on a GM W-body (1.5 and 2.0)..... its probably the rear ABS wires..... or the pass front due to oil and P/S leaks
That was great! I can always learn something from your videos. Now if I can get my 2008 Nissan Altima Hybrid immo and ECM going I'll be a happy camper. The dealer can't fix it. Dead as a door nail.
Ivan, been following you for a while. Thank you so much cause you’ve helped me through some pickles! I was just wondering what your thoughts are on the current situation with the EPA and aftermarket performance industry?
Great video job Ivan , is that p.t. cruiser still running ok with that Bosh relay you installed instead of replacing that $$$$$ tipm .
I will guess the gear is spun (roll pin) on the cam sensor which drives the oil pump, had one the stripped the gear.
Extremely common problem on those... Good catch with the scope! Many 4.0 jeepers are all too comfortable reaching for the ckp on a crank no start with aftermarket being the only option.
You right man about fuel flooding on the cylinder for jeep, I had 96 grand Cherokee Laredo, if the car doesn't start for the first time, or more, you need to push slightly on the gas pedal, and start the car, and keep your foot on the gas pedal for a while and and keep the engine RPM between 1000 and 2000.
IVAN, the MIRACLE WORKER !!! It wouldn't run and sounded like crap. BUT, Ivan got her purring like a kitten !!! 😸😸😸😸 Great Job !!!
Within the past three years. I have bought six 99-04 Jeep Grand Cherokee's for less than $1000 each that would crank and not start or just randomly die. Using the key switch to pull the codes all six showed the same thing. Bad crank sensor. New crank and cam sensors had them running great. It only takes about 45 minutes to replace the crank and cam sensors in these Jeeps.
Great job Ivan.
I planned to replace the crank sensor on my 2004 Grand Cherokee 4.0. Looks like there might be more to it than I thought, like synchronising with the cam signal. Not sure I'm ready for that.
Just discovered your channel, feel like I hit the jackpot. 👍👍👍
If people would stop messing around in their vehicle when they have absolutely no clue what they’re doing we would not have these interesting videos :-). So guys, keep fckn around and keep the vids coming….
Wow, for the 1st time my initial guess was correct. As soon as I noticed no RPM signal when cranking I said to my self. Throw a new CNK sensor and sync it and it will run. !st time I've been right LOL!!!!!!
