I Made Such A Dumb Mistake During This Jeep Grand Cherokee WJ Diagnosis. But I Do Fix It!!

[@chevymontmarlo]

I always love seeing WJs on here, arguably the best-looking gen, last one with the 4.0L the interiors were pretty nice. And just the one I liked the most

[@ericferguson5231]

As a mechanic I think aha moments are common in diagnosis. Keep the videos coming I didn't think it was wasted time. Thank You

[@noberet]

Great episode! My 1996 XJ 4.0 had a similar O2 sensor problem. The harness to the upstream melted the insulation and shorted. Wires were too short to clear the exhaust manifold. A great shop in Knoxville, that's gone now of course, fixed it for a very reasonable fee.

[@3012630126]

Dex, I want to thank you for the info. I believe the wiring diagram you looked at is for a right-hand drive 4.7L, as in overseas/England driving on the right side of the car. The wj FSM FIELD SERVICE MANUAL addresses both left and right hand driven vehicles. I do not know if it makes a difference but there is a left-hand version of that wiring diagram. Anyway…..Keep up with the great wj teaching videos -i’m a 59 yr female who knows close to zilch about cars and i just adopted a2004 wj: GC Laredo 4.0L . I was raised by brothers that were motor heads and shop-jocks (their labels not mine). I love my garage time. Thanks for the great content! Andrea (a torque “wench”)

My first test for cranking no start is to spray fuel in intake

[@jayroyce20-Garage]

i almost junked my 2000 jeep grand Cherokee today because of coils. I was chasing sensors here and there just find out it was the coil! I didn't want to get rid of my jeep because I like it a lot. and when I first bought it I blew a fuse for PSM Battery fuse not knowing at the time but got a new fuse and it's a great jeep with 300k miles.

[@Dmowery5036]

Yes!!! Finally a 4.7 👍🏻👍🏻👍🏻

[@graflohner839]

That jeep is identical to mine. Only difference is mine is quadradrive. I can't wait to see what you do with it. Mine got about 16-17 mpg highway with the front driveshaft out. Man I'm stoked.

[@dh2360]

Many times I’ve had that ‘A Ha’ moment when trouble shooting. Feels good to fix things.

[@buckchase1]

keep cranking out the content! We are lovin the knowledge and seeing how you work these Jeeps.

[@James-yp5dn]

Excellent diagnostic video 👍👍

playing this in the background while in the garage so I have a working buddy

[@2dollarrip571]

Hey man we need a real world review for this gluetread traffic kit!! You are our guy!!!

[@dexjs]

No way!! That’s on my list!

[@keithmullins6267]

So appreciate the content. Really enjoy listening to how you diagnose stuff. Learn something every video. Bought an old 96 grand Cherokee with the 5.2. Needs alot of work but your videos give me inspiration to work on it. Thanks much

[@Baumann4.0]

You have a great show. I look forward to watching you fix stuff. Have a good one, my friend. Oh I just ordered some stuff off your website

[@cobyburrow9339]

You make some great videos, always good content!

[@rcmachinehead4085]

I have the same exact WJ down to the rims mine is woodland brown with 4×4 and a 2.5 inch lift and next is 32' falcons

[@garyd.7294]

Dex, your video was cool, a head scratcher. I have an '01 Grand/4.0. 3"lift Core 4×4 adjustable control arms. 17" Wrangler JK rims w/Cooper AT3's. 175,000. doesn't burn a drop of oil. I've had my share of electrical gremlins. But one question, how come you didn't try Chrysler's best kept secret for '99-04 Jeeps. Just turn the key to the run position 3 times, on and off and the pcm will give any code for what most problems are. Trust me, I love my ole Grand, been there.

[@paulkomatz284]

Good video. I learned a lot, thank you!

[@willcrosbie8806]

I’m definitely guilty of ignoring things I’ve replaced before no big deal 🤷🏼‍♂️

[@petegrant7496]

My 99 wj 4.7 had loose worn out plug to the pump. It wood die then re start. After 2nd pump I straight wired it and was good. Also used a 4.0 pump the 2nd time, there the same. 4.7 is a great engine

[@markandmellwhiteley7995]

very entertaining Dex, thankyou

[@edwardBates-ez8nd]

wj content !!! yes please

[@eddiereichel9354]

I always find the problem vs bypassing. If u It's rubbing on 1 wire it's matter of time till it gets onto the next

[@dustinkile7705]

We have all done it. Keep it up brother.

[@Jgriffin0808081]

Keep workin on Jeeps, and I'll keep watching brother

[@Chavezrobert70]

Thanks awesome to see real live problems the good and bad that's how we learn 👍👏

[@papatomsthoughts]

Congrats on break8ng 100k followers, well deserved.😊😊😊

[@tonionzo4037]

I Always learn something from your videos.

[@Deadbuck73]

Great episode! I wish you could show how you fire them up with your finger in the fuse box!

[@Deckers_fab]

My 99 xj ain’t had o2 sensors for about 2 years and runs fine. I had a code and it sounded like it was cammed I cut all the o2 wires off the sensors and unplugged off the sensor and it runs fine now. It’s just a trail rig

[@Dmowery5036]

Awesome video!! Very happy to see a 4.7 😄👍🏻👍🏻. I really want to put a very small lift on mine. 2-3” no more. I really like my 4.7 SE. it has almost 240k miles and I’ve only replaced power steering pump, starter, and water pump and a U joint.

[@mitchellsandlin7161]

Prolly throw some fuel stabilizer and or cleaner in that tank a few times hopefully maybe clean things up alittle.

[@eddiereichel9354]

Bracket in back for charcoal canister rots out and the wire to vent valve shorts asd fuse

[@genobrn8743]

Wild Dex, simply hilarious! Was that your head banging against the lift- out of camera view-hahahaha. I had a new skid plate recently powder coated gloss red(straps zinc plated) as the one on my 01 WJ is disintegrating. I have a new fuel pump, gas filter and tank cleaning solution and ready to rock and roll on this project in a few days. Your video inspired me not to procrastinate on this project- keep the videos coming👍🏿♥️🤍💙👍🏿

[@tpb1717]

Have you ever dealth with the common SKIM issue? My jeeps been sitting in my driveway for a month now and it won't start and just throws thr key light on the cluster. Starts for a second then dies, or just cranks and doesn't turn over. New pcm on the way with the SKIM delete. Hope that works...

[@firstwordcar]

18:45 That moment when you just need to think about the choices that led you to this point in life 😂 If you work on cars enough this is bound to happen. At least you fixed it and solved another problem you didn’t even know you had haha

[@Max23653]

so about that hydraulic fan solenoid how much and will you ship it with the pigtail for the 01 wj 4.7?

[@travis8231]

From watching your videos, I'm kinda scared to tear into my wj with the 4.0. I just recently bought it knowing it needs a head gasket replaced, but seeing how prone the heads are to cracking and then the pistons also cracking. Not sure if I'm ready for that can of worms lol. Love the jeeps tho. I'll definitely be looking you for parts if my head is cracked lol.

[@xjrope]

Are all those fuses and relays good for tj's too? I've heard there some different ones. If they work I'll buy some

[@sriles1676]

A little more info on the relay hack might be helpful. Good stuff, keep it up!

[@kyridgejumper]

Really enjoy this style of video

[@jeremiahffvanorman7767]

Keep up the vids I'll keep watching

[@DependableAutoTruck]

carmin is a wiring diag for android cost 50.00 per year

[@CKILBY-zu7fq]

My first statement was no fuel. I just had this problem with my 81 jeep c-j5 Oh yeah, it has a 88 4.0 OBD1 system, when it acted like that , the first thing was to establish if its a fuel delivery problem, so I sprayed starting fluid, turned the key ,fired right up, looked a bit farther and shit when I realized I was out of fuel. Ha ha ha. 😅 its so funny. Runs now. But I have been wondering how to determine if you have a stroker moter or just cam. Because mine has a lobe to it and I know thats not a stock sound of a 4.0 motor. Any ideas? 😅 peace.

[@DillonStaton]

Beginning of the video I was thinking fuel pump.

[@Tater4200]

I always check for main 2 first. Fuel.. And fire. Ill listen for the fuel pump. Then check spark. After that i start diggin deeper lol

[@b2therob_]

It’s usually the first thing I check when my shit won’t start.. fuel pressure

[@leveluplife8585]

Fuel filter needs to be done too, so bet it’s just as clogged as the pump if not worse

[@jefffair6055]

Can you make a video of cruise control problem on xj

[@rustyedmoore]

Hi Dex, love the channel. I know your always looking for content ideas. Could you do a video on your drill powered engine hoist. Ps. My son and I have been working on his 1998 XJ using your videos. Thank you!

[@michaelbarnhill2685]

Nothing hack about creating your fuel pump access panel. You can cut the square fully out, weld some little tabs to it, to allow it to not fall.back in....the use RTV to seal the cuts back up. 100% proper and clean access port from then on. Also...cutting your wires is a hack, that will create electrical gremlins in the future. Only way to avoid/minimize these gremlins, is to do a proper solder job. I use a "Lineman/Western Union" splice, than soldered & shrink wrapped. Crimp connectors will come back to haunt you.

[@davidprice2226]

Get back to the real jeep the xj 😂 I been working on mine 1996 139000 miles I'm the 2nd owner gave it to the wife to learn how to drive 😂if she doesn't f it up I'm wanting to do a lift kit on it with like 45s not something to bounds over rocks but to crawl over them thanks for the video and help save the jeeps

[@Bilskirnir3124]

It isn't an XJ, but it's still a Jeep. The WJ is cool.

[@coletyusha1357]

WJ 4 life babay!

[@Bilskirnir3124]

@@coletyusha1357 I prefer the XJ myself, but more for you!

[@danieljohnson8437]

Howdy!

[@richwood8650]

Hey Dex, didn't you say you heard the fuel pump run? Gauges are handy!

[@RM-kc6qk]

I have a 2000 wj limited that always has a check engine light basically a no bus from the TCM to the ECM but the transmission works like it should. I've towed 6000lb with it. It was my daily until the Tcase went out. Have you seen any other 4.7 limited with a transmission code that works fine?

[@423gamble]

not me screaming check your fuel pressure to myself every time a fuse blew cause i knew it didnt matter lmao

[@nlnl4523]

Back oh in 2015 I had 1 jeep grand cherokee zj . One time I was turning into my apartment parking spot and as I was about in my spot and the jeep died. It ended up being some small fuse in the fuse panel

[@seanmataya2290]

Ain't got no gas in it lol

[@TheJoeyBones]

Just before your existential crisis @18:35 you were feeling something under the intake, but what was it? The fuel hose? Or something else?

[@bassinshankles]

I watch everything you post here and FB you can say it's stupid and no hard feelings for not watching but you seen fit to share it I'll watch it regardless.

[@thousandoaksauto1696]

I hope you get to work on that WJ driver power seat not working, cause I have the same problem. "The driver power seat does not work"! Help!

👍

[@BilliamNye1]

i have the same engine and have a misfire on cylinder 6 new coil and new plugs. the engine was remaned 35k ago the misifre is only at idle also. any ideas? seems to be less misfires with the A/c running. ram 1500 thanks Dex

I have an 07 wrangler I have power to the dash but when I try to start it nothing happens and also don't have power to obd2 plug any suggestions

Check all of your grounds. I had the same year Jeep with the same problem. Crusty ground connection on the engine block.

I got a 2.5 in my Jeep it starts up and then cuts off I changed the ckp it didn't change if I up plug the ckp it what start or the cam one at at time it won't start have both plugged in it starts and then cut off it gives me a code po320 this is a new computer the one came in the jeep went out and this is the second new one I got the frist one they sent they put The security in it. My Jeep doesn't have security. It never has 1998 Jeep Wrangler, 2.5 now it not give me the key code no more just the po320

[@timmythompson435]

Please help 🙏

[@stevewalther2293]

They !!!

[@Mauser1965]

Not on him as he's just trying to help. Show me something that should be simple isn't. Why you could give a brand new Stellantis and I'd trade it for the oldest model possible which has a simpler system. How many relays there are compared to a XJ? Like others, if it cranks then and got spark then it's fuel issue as it only takes those three things. For the WJ owners.

[@williamsauer658]

LOL

[@rudybishop9089]

Ahhh Dex . . . the next time I see you hammering the ship out of a ‘goot’ Cherokee - I’m gonna jump in my Wrangler - drive from California to Hootersville - right next to The Shady Rest - and break out a can whop-ass ! “Thy shall not abuse little baby Jeeps”.

[@cheapdaddy99]

It ain't got no gas Dex. 😂

i wish i had your intelligence to identify why my ac doesn’t work in my WJ. I’m leaning towards the orifice tube / evaporator core. my ac blows weak cold air
