Heckkkkk yea had a fun time on this one. Just sucked that I couldn’t get my ice cream :(

I hope Eric got you 2 scoops along with the wings n beer. Fun video

you should ask President Biden for Ice cream. he's an expert because of his frequent national ice-cream eating tours around the country

I watch a lot of mechanics fix it shows and I mean a lot but hands down you have one the best on the KZbin very impressive

[@ADVANCEDLEVELAUTO]

Thank you very much. I truly appreciate it!

[@stealthg35infiniti94]

Good Diagnosis. Normally I would say tow that Jeep POS to the junkyard, but that vehicle has been taken care of and deserves to fight on. Nice to see an old vehicle that has not been abused to death.

[@Garth2011]

The day in the life of a mobile mechanic ! Always carry a long set of jumper cables...they don't require charging up. Nice diag. I was hoping you would have gotten the okay from the customer to bring back a new battery from the parts store, 700 CCA or greater. Peace.

[@ADVANCEDLEVELAUTO]

He had a warranty on the battery at Walmart, so he was going to replace it after we got it running. Thanks for watching!

[@Garth2011]

@@ADVANCEDLEVELAUTO My sources have lead me to believe the Walmart Batteries, their upper line, are the best value out there on average.

[@GeorgeMalonedj]

I keep a jump pack and jumper cables that usually never get used because jump packs are just awesome! Cables would have came in handy.

[@barstadryan]

Dude I absolutely love your videos and you really take the time to deep dive into the issues and prove it without just shotgunning parts or guessing the repair.

[@gureno19]

This is proper analysis! Not just spraying the problem with new parts

[@swedesam]

As an aside, I can attest that the Autowit is the Jam! Got one on Eric's recommendation and it already saved me from a dead battery reading at 6 volts.

[@scientist100]

Scotty recommended it, I dont think I would recommend it as it is not strong enough on it's own to start a car.

[@dtnel]

@@scientist100 But if you have a car or battery charger, booster nearby you can always make sure it's full on way to a call just in case. I ordered one. It was $30 off retail price on Amazon today so that made the price more appealing as a tool that could get me out of a jam on a job. If it's a job where it'll be overnight then I generally take my little $35 NOCO 1 amp charger and use that so it charges the battery and if someone were to steal it night like I would be out $100 rather $35, actually about a little less than $32.50 as I have a couple plus a 5 Amp charger. 100Amp schumacher maintainer for programming, Die Hard booster box that i've had a few years I got from Menards for about $119 before taxes at the time as it has a built in inverter, 5v USB plugs, mini compressor for airing tires up in a jam.

[@MERCNRY]

I noticed no activity on the dash cluster initially. Then a reading on the fuel gauge after PCM change.

[@timmaysmitty]

I have a '97 GC that's purely an off-road toy that had been parked for over 3 years. I went to start it about 6 months ago and had the EXACT same problem as this customer. I have scoured the internet for answers, but couldn't find anything definitive, but it wasn't a huge deal because the GC isn't a daily driver. I started looking into it more just a few days ago. This is BY FAR the most informative video I have seen! Very well explained, gentleman! Even before seeing your video, I ordered a reman PCM because it really couldn't be anything else.

[@jamesblakely2916]

The e c m is really easy to pull a part and resolder the bridge as needed and only takes less than a hour and will save you hundreds . I've done this on several of the Cherokee jeeps .

[@CubasAutomotive]

Great diag guys! Oz is too much fun! Every where we ever went, like NYC, tequilas were always on the menu!! You two have some awesome personalities, and hopefully we'd all be able to meet up some day, with good food, music and family!

[@ChadtheDad23]

10:50 funny thing about that is when old computer parts start to act funny or not work anymore, people put them in the oven at a certain temperature for a while to get all the solder joints to reset, and it works most of time

[@foxwithtubesox1075]

Wouldn't the plastics melt before the solder does?

[@ChadtheDad23]

@@foxwithtubesox1075 it's really a last resort for a dead board, but you clear as much stuff as you can from the board and hope for the best. In the case for this vehicle, you'd have to remove the board from the shell before baking it.

[@rikkhaynes1391]

It’s a certain kind of “high “ when you fix cars. Great feeling!!! Good job guys!

[@bebomarin]

You two make a great team! Really great to see you guys go out afterward for food, drink, and bags. More!

[@mikechiodetti4482]

Heck yeh! Great diag, reman part, jumper problems. But you guys kept at it, and the sweet smell of success when it ran. WOOOO HOOOO ! ! ! The icing on the cake.....food and drinks! All in a day's work! The life of a mobile tech! Keep up the good work!

[@ADVANCEDLEVELAUTO]

Yes! Thank you!

[@litz13]

Two fun things about the 4.0 ... 1) it will start and not run if the battery is dead. You have to throttle it manually to keep the rpms up. 2) unless you use a Mopar CPS, it'll never run right (or for long)

[@johnemerson7831]

Oz is the man! Nice seeing u guys hanging out. Always good stuff. U guys r the best.

[@fredsalter1915]

[@Bekim8310]

Great video and excellent diag! But if I may, nothing replaces good ol’ fashion jumper cables!

[@fredsalter1915]

Yeah, that cracked me up! Two heavy-weight diagnostitions don't even have a set of jumper cables???!!??!!???? They both still rule, however !!!

[@RollinPutts0]

Just had my wife's 2021 wk2 with the V6 fixed for this issue. Could only get it to crank and not fail when using the remote start. It would always start after the fail. After 2 dealer visits they finally tested the Fuel system and found it needed the filter and sending unit. Little to no pressure, but no error codes or anything. All at only 25k miles. Crazy. I know this video is on an older Grand cherokee but hope it helps someone who is searching fort answers on a newer jeep.

[@DJ-tn7vj]

Going after the 5volts ref is 98% guidance what to go after. I have learned that. Eric and Oz.good work

[@scientist100]

In this case the 5 ref was there 😅

[@DJ-tn7vj]

@@scientist100 which is also a good thing. This eliminates wiring issues or a sensor pulling the circuit down. Now on to the next test. Process of elimination

@@DJ-tn7vj 5v ref usually means the computer is alive lol, not the case here since it wasnt talking but what if the con lines to PCM were not good? This test did not eliminate that important step.

You guys did a great video! Clear, concise, easy to follow. Especially for those of us out here that aren't strong with electrical diagnosis.

I have a 2007 Chevy equinox and they made this vehicle from 05 to 09 I think. I’ve change the crank sensor and had problems cause wouldn’t start ruff idle and cut off. The point I’m getting at when you change the crank sensor replace it with the exact part manufacturer that came out from the vehicle not all manufacturer wire there crank sensor the same.

Common to have the same issue be the crankshaft position sensor also. Can CPS also cause check engine light to appear sometimes then go away?

My first guess before I get to the diagnosis is a fuel pump issue.
