EPIC Jeep Crank No-Start (4.0 Inline 6)

[@noneyabiznass251]

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.

[@PineHollowAutoDiagnostics]

Yeah a scope can cut that diagnostic time from months to minutes 😁😉

[@noneyabiznass251]

@@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.

[@ThatEEguy2818]

I would've taken one look and said, "the dealer was right, the nearest junkyard is..."

[@Garth2011]

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.

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.

[@saaaron5213]

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.

[@billziegmond4943]

By the sound I was waiting for a rod to come through the side. LOL

[@CubasAutomotive]

I truly thought the same. The audio through the camera can play some harsh tricks 😁😬😅

[@garymallard4699]

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...🤔

[@enesfazlic6017]

Yeah same here.

[@toasteroverdrive1097]

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'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!

[@donkaiser6704]

Excellent diagnostic work. The customer made a good call bringing his vehicle to you!

[@somerandomguy3868]

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

[@jamesofallthings3684]

Dealerships like work that's easy and expensive.

[@frugalprepper]

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.

[@wyattoneable]

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.

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.

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.

After trying to program a second remote for my 2001 lesabre by following a KZbin video I had a jumper wire and was supposed to attach it to a pin on the obd2 connector, it was dark hot and humid out, I should've waited until the next day but didn't, I touched the connector with one end of the wire and wasn't paying attention to the other end, it was touching the emergency brake bracket, there was a spark and I thought I blew the car up, I had a no crank situation, so I did the right thing and checked the relays under the back by pulling them out one by one to see if any looked burnt, again I was very tired and now completely aggravated, what I didn't realize was that I put two relays back in the wrong slots.the no crank turned out to be the pcm fuse, once I started the car I had no turn signals, no speedometer and a few other things like the power trunk release didn't work, I was sure I did some major damage, I went to a local mechanic who I've known for 30 years, I explained what happened, he told me to junk the car because it would cost too much to try and find the problem, a couple of months went by so one day I decided to take another look at the relays this time whe I wasn't dead tired and it was like a light shown down from heaven, I looked carefully at the diagram on the fuse cover and realized what I'd done, I put the one relay where it was supposed to go with the engine running and the tach came face to life, the directional signals, I was so happy I ran inside to tell my sister who was visiting from Colorado and gave a big hug, I waited a day then found the misplaced trunk release relay so everything was working again, the moral of the story is, try not to do work when you're tired, haste really does make waste and take your time and do your best, perseverance usually pays off.
