Jeep (WJ) Grand Cherokee won’t start? Stalls + Key Light + No Gauges

[@andrewm5566]

I had the same problem. Cleaned the grounds, tried leaving battery disconnected at night (helped a bit) but the fix was to spray lots of electrical cleaner on the connections to the ECM, been good ever since

[@WhisperingWildMarketFarm]

That’s awesome!! Glad yours was an economical repair. Thanks for adding your solution to the comments!!

[@Mo_Money73]

Man thank you for making this video. I bought a jeep and it started having this exact problem and I’ve struggled to find anything similar. I’ve tried everything I almost sold the jeep after this ima have to give it a shot.

[@WhisperingWildMarketFarm]

Your welcome! I hope it’s useful and wish you the best of luck on fixing yours.

[@TimMoney]

Just sent ECM to all computer resources removed skim. Now it starts even when key light son. But still experiencing random shutdown while driving

[@CaptainMorgan68OU1]

Did the computer fix yours having same issues just bought it doing exactly same thing watched this and did as you did if it did fix it where's best place to get one

[@tv10morehead]

IF it cranks without starting on some models it could be the 10amp PCM/ECM fuse under the hood has a hairline break that is hard to see, can happen if you jump a dead battery, so swap that fuse it is labeled on the lid which one it is . ALSO if like me you get a spare dumb key for the door and you put it in to start the Jeep, it does the same thing if you or the wife uses the wrong key. & The Keyfob even works to lock and unlock doors but it acts like the keys were 'deleted', after 1999 the error code Pxxxx comes up for the skim communication, but it still can just be that 10amp little red fuse by the battery, since he does not mention it , check that first with a bright light or just swap it. & I'm rootin for you hope that's it.

Good To know! Thank you for adding the info!

My 99 v8 is doing the SAME thing happens when it’s get wet?! They pulled horn fuse out why??? Shows a p1698 too! I am going to check fuses

[@WhisperingWildMarketFarm]

@@Paintgirl74, This seems like it would be very frustrating to find. Wet could be water / condensation getting someplace it dose not belong shorting out something or the cooler temps opening up bad solder joints. If this is a Jeep with a distributor I would strongly suspect the cap and say try replacing that. Google says Jeep started moving away from distributors in 99 so may have one. Checking / cleaning ground connections is a good place to start. Not sure about the horn fuse. A quick google search shows a few people getting that code but their trucks still running so that suggests it may be more of a bus issue like when it’s wet things can’t talk. From what I read any device on the buss going faulty can mess with the bus / cause communication problems. There is a connector under the steering wheel of some Jeeps that when pulled can disconnect portions of the buss In my Jeep the truck would still start but things like door locks and displays stoped working if you pull that when it’s not working and it starts then you know the problem is with one of the peripheral devices. If it still dose t work then putting a scope on the bus to see if the voltage stuck high low or noisy may help. Otherwise it is disconnect devices like the tcm/bcm/pcm/ecm until the fault condition goes away. If the fault condition does not go away when the devices are unplugged then it may be wiring . If there is no issue when scoped try re seating the bcm ecm/pcm and tcm connections. If it’s still not working after that I’d start suspecting a bad solder joint on the tcm or pcm/ecm. Else this could all be a red herring and you just have a bad coil pack that dose not like cold / wet conditions. Thats about all I’ve got for speculation on this issue. I hope your able to get this solved.

I had this exact problem last year, it was the ground under the center console near the ABS Module, I had swapped out the heater core a few years prior and must have left one of the ground screws hand tight. I tightened it up and got my gauges back and the engine stays running because the immobilizer is grounded

[@WhisperingWildMarketFarm]

Interesting! Thank you for posting

[@markgabello58]

Yeah, that's systematic. I didn't turn alarm systems skim card. Something's wrong with the alarm system computer won't let the vehicle start

[@mechsupernova]

When I went to start mine earlier it clunked, all the interiors lights went off, all the gauges went out, then all the hands started doing a self test everytime I tried to crank, none of the battery terminals where loose so I removed the positive went and turned the key a few times and put it back and everything was good, never seen it so this before and i can't find anything online about it

[@WhisperingWildMarketFarm]

Hum. This sounds like there may have been an issue with a connection. I find removing the battery cables cleaning both the battery and the cable clamp then re connecting them usually fixes this. Often there is a good enough connection that low amounts of power can flow but once a high draw like the starter kicks in there’s to much resistance and the voltage drops or disappears causing everything to go dark. Thank you for posting your experience!

[@Mark-xo9sn]

I tried to get a voltage reading at the skim module and couldn't get a reading. And we pluged into the obd port and it didn't even get communication at all The engine cranks but I don't even get the 2 second start All functions in the door work. With no power at skim connector what does that point to?

[@WhisperingWildMarketFarm]

The dealer also could not successfully keep a connection to the old computer in the Jeep in this video. Since the other devices are working it seems like it could be the connection at the computer. Those are known to develop corrosion and what I ultimately think the issue was with the old computer I had. There are a few KZbinrs that have videos on diagnosing and fixing those connections. The bigger issue is getting the potting compound off so you can reflow the solder joints . If you’re not getting voltage at the sensors it could also be the voltage regulator ( also in the pcm if I remember correctly correctly) I’d still recommend checking though everything especially the grounds. Bad grounds cause really odd symptoms

[@Mark-xo9sn]

Well, mark here, one ask forum said check the crank position sensor. It took a while to get the small cover on the trans tunnel by the foot duct.. then try to unplug the cps lead and it was dam near impossible but the connection was restored and the problem was solved. Key light gone. Engine started and stayd running.

[@WhisperingWildMarketFarm]

@@Mark-xo9sn that’s great news!! Glad it’s working now and thank you for adding your knowledge to the posts.

[@domstarkey7279]

I fixed my door wire I jus learned if you turn your key to assessor 3 times an then it work granddaughter told me it happen to her a time or to

[@WhisperingWildMarketFarm]

It seems to be a common problem with these Jeeps wires just seem a bit to short.

[@PabloLowondoski]

The electrical in the driver door ,ehat would prevent it grom starting,,?

[@WhisperingWildMarketFarm]

Potentially. The door locks and window regulators are controlled by a computer that shares a communication bus(wires) with the other computers in the vehicle if the bus gets shorted it could block the other computers from being able to communicate.

[@PabloLowondoski]

😊i think also the key fob or security system might be a reason and possibly a short in the relay box

How can I fix this car problem? It's a 2005 CHRYSLER 300 3.5L V6 2WD AUTOMATIC 150,127 MILES The car listed above is limited and according to the client had a horn issue so was taken to a garage. Although the horn later worked, a more complex issue happened to the car. A no crank no start and also a crank no start, whenever security light came up it doesn't start or start and stalls immediately. Infact, ECM was replaced by the engineers but that didn't fix the issues. I finally fixed all these issues listed above with both new and an old ECM. kzbin.info/www/bejne/pHekZpx-rdyLlcUsi=rSRKrmfj4ywRXIQX. That's a brief video of what I'm trying to explain. When I was about to go, the client pleaded for me to help him fix these issues below, such as, ABS, airbag, traction control light; hard starting,single turn signal for both sides doesn't work but hazard light blinks normally when the switch is turned on, wipers doesn't work too. Mostly for the trafficator / turn signal that wasn't functioning, what could make it to be inoperative and, how can I fix the problem in that car? Can you guide me please, on the repair procedure to fix the problem? This were the codes I got below drive.google.com/file/d/1nZQtpE8DuGGQoeA4Lc9Iob-BBbRfzs0H/view?usp=drivesdk Does it require a TIPM or trafficator switch replacement? Please, how can I carry out a test to verify if it's TIPM or a trafficator switch that is faulty? www.startmycar.com/chrysler/300/info/fusebox/2005#anchorfusebox1. That's the fuse box diagram I saw online In addition, when testing the fuses at the trunk I noticed that not all the fuses were available, some were empty. Thus, I decided to swap fuse 4 that was available to 5 that was empty. As I did, I noticed an immediate electric spark just by the fuse touching the empty terminal meant for fuse 5. drive.google.com/file/d/1qqOKGWB08fWkArDwwx9hQ8QLU0zU5Ang/view?usp=drivesdk. That's the link to what I'm trying to explain. I tried that again with a known good fuse into that location and noticed another spark/ spike. why is it sparking whenever I attempt to put a fuse in that location? I compare that fuse location where there was spark to another good working 2005 Chrysler 300 and saw that there was a fuse in that location. Could that also be responsible for the cars turn signal and wipers problem? How do I address this sparking problem in that fuse location? When I finally succeeded to start the car, as a result of checking the turn signal switch and wiper at under the dashboard using my testlight connected to batt + (pin 16) of obd2 connector and activating the hazard light, when I touched a particular blue/white twisted wire the hazard light seemed it wanted to stop it seem like something is wrong there, when I touched the blue/white wire again the car problems reoccurred all over again. Security light remains ON, lightning bolt light, etc came back on and car didn't idle if it even struggle to start and sometimes doesn't start at all. Fortunately, I was able to start the car again. But the no turn signal, no wipers still remained, how should I fix these ones?

[@WhisperingWildMarketFarm]

Hi David, That sounds like quite the perplexing problem and it sounds like you have been able to fine quite a bit of information around it. I’ve no experience with those cars myself so I can only offer some basic advice. Check grounds.I can’t tell you how many weird and unexplainable electrical issues have been resolved by locating and cleaning up ground connections. Look for damaged wires. Many of these systems use a shared buss(wires) for communication so damaged wiring in an unrelated spot can sometimes cause other systems to malfunction. Where wires go from the body of the car to doors is a common spot. You may also want to check for corrosion on junction points (typically around the firewall or in the dash). Rodents tend to like to nest in or around fuse boxes and chew wires. Aside from that if you think it’s a buss issue which it kinda sounds like you suspect then you could try disconnecting the other devices on the bus. I hope that helps and good luck.

Did it work I have same issue

[@WhisperingWildMarketFarm]

Yes see the follow up video How To: Jeep computer replacement SKIM removal kzbin.info/www/bejne/hoGQoJmFrN6FhMU I suspect that it was the solder joints on the main computer. So I replaced the computer.
