Helping a buddy troubleshoot the stalling problem with his Jeep. This video recreated exactly the behavior of the vehicle (turn over while engaging starter then stalls out w/o starter kicking) and confirmed what I had read on forums about it maybe being the PCM / ECM / ECU. Thank you!
Thank you for this. I've been researching how to diagnose my ECM for over an hour and no one else has showed opening it up and what to look for INSIDE it. THANK YOU! Unfortunately I do not own a pistol so I am not able to recreate the shorts, but very helpful! Hahaha
Wow, that was a good one. Especially adding some bullet holes & seeing how it made the jeep barely run & then not run at all. Nothing beats experience & that is what your sharing so we don't have to bang our head against a wall trying to figure out a problem. Thanks.
THANK YOU, That settles it....now to find a junk yard to swap out my recently discovered defective ECM.....no im no mechanic....but I always like to be a little informed before I take my 2004 GJC to the shop. Good Info man
BleepinJeep have 95 grand 4.0 stalls out still drivable revs up and down no check light herd around u can loosen screws on the pcm job cause they josh it up should i give it try have u urself had same prob iev had four of these things wont go back to anything else good runners let me know bud thanks
I bought the Jeep high performance computer for my '89 mj when the Chrysler dealers had only 12 or 13 left in their inventory. Fortunately i had removed it for troubleshooting prior to it catching fire and burning. I now have it in my '90 mj
I would suspect it just needs a tune up. New spark plugs w/ correct gapping. New cap and rotor, new spark plug wires. If that's not it then my second guess - a vacuum leak.
If you ever need one I've got a shit ton I'm a parts hoarder, would love to come to Denmark, been to Sweden and Norway beautiful place I've thought about moving there skoal brother
I check the computer first with a test light at the coil and then at an injector. You should get a pulsing light at the feed wires. That proves 2 important functions are working. The crank sensor, and the computer. Then I start checking voltage at various sensors. If that is good then likely the computer is good. Symptoms will at that point direct you to potential solutions.
OMG Hi-larious! i didn't expect to learn anything from this video after seeing you shoot holes thru your ECM but was happily surprised when that wasn't the case! it helped me seeing your vehicle still ran even with holes blown thru the board! I've been trying to diagnose the cause of a U0107 DTC in my car and all the voltage & continuity checks have been normal. I replaced the TAC module so the only thing left that i can think of is a faulty PCM but before watching this i assumed there would be more issues than just the electronic throttle if that were the case. thx 4 this!! it gives me a lil more confidence in replacing the PCM. only prob now is one of the connectors is stuck in the PCM. I've got the other 4 out but I'm almost wondering if the dealership super glued connector A bc I'd just taken the car in for a PCM recall where they put a cheap little plastic piece over it and i wouldn't put it past them to mess it up thinking I'd be forced back there 2 have them repair it
Gotta love a video that starts out with shooting a jeep part! I think my ecu might be bad in mine. I seem to have no electric connection. Acts like battery is dead with full charge. Everything else is good. Had a mechanic swap out my ecu but I think he put in another bad one 🤞 I can get this remedied
good point on the reflash, ive never owned a car that new so i didnt even think about those new fancy computers! Does anyone know abut what year cars started using ecu's that need to be flashed when swapping?
I know this is a very old video, but hoping you see this. Got an 88 2.5 Comanche, blew the engine on the drive home from buying it so everything worked before that. Swapped a 94 wrangler 2.5 into it, had to Frankenstein a little bit nothing too serious. It cranks but won’t fire. Changed cap, rotor, plugs, wires, ignition coil, distributor and tested the crank position sensor and got 197 ohms so I know that’s good. You think it’s the ECU? Even though it ran fine before? And would I put a 94 wrangler ECU in it or replace the original? Hope to hear from you
That reminds me of my first XJ. It was a '98 sport that I swear was struck by lightning ⚡. When we bought it from a neighbor he told me it just needed a fuel pump when they parked it 7 years before that🙄. I ended up replacing almost every sensor on it. The ecm took a dump and we borrowed one from a friend and tried it. It would start and run about 5~6 seconds and for🤨. Took me all damn day to remember his XJ was a 2000 or 2001 and had a chipped key..........
My pcm went out on my 97 jeep zj and cost me 220 dollars and a core charge also my coil shorted out and shorted my pcm out and ihad to get a new one if u get a used one u have to get it flashed to ur vehicle or it will not run right took me months to figure out why my pcm went so if i was everyone with a jeep id go get a new coil before urs shorts out
I have a question. I purchased an 04 Jeep Liberty, less than 24 hours I got a no bus reading on my cluster. Replaced the cluster, BCM, and just replace the ecm. The dealership said my network is down, that's what the no bus is. So now after paying for the repairs my jeep won't star. It's completely dead after starting and shutting off! 😭I'm in such need of help
AS happy as shooting it would make me, it blows my mind the wiring lenght in the driver door. See i have discovered the alarm runs thru it and when my1985 cherokee has a stalling problem its because of those wires..i have every one nail polished to color. code..and when the drivers door gets swung open by wind or me the stalling atarts again..I love the video ..Thanks
well you didnt say what kind of vehicle you have but the older cherokees are under the dash, big silver thing. And the newer cherokees are on the left fenderwell under the hood, black. Just unplug, unbolt, and put the new one in.
Sounds like a metal old minelab detector. So hears my issue I got in my car the drivers side of my foot well was waterlogged next I notice a warning light car icon with spanner through it came on the dashboard milometer graphics.keep partly disappearing and I could smell smoke, took it to a backstreet garage he gave it a clean out under the bonnet , unblocked a pipe and got rid of debris. Hes old school doesn't have diagnostics machine or a thinking brain it seemed. He couldn't explain why the revs are so high when I start it up and why it's fluctuating. I think its water that has got into the ecu but.once I start driving it it's not to bad the revs drop back to something near normal but not quite. Just had a mot on it a few weeks before and it passed that. I am just wondering if it's safe to drive and what the worst possible senario is? Do I need to invest in a crash helmet or will the engine just die overtime and how long do you think I could drive it like this? Grateful if you could help sorry I can't divulge the make or model of the vehicle as I don't want to embarrass myself haha.
I have a 91 Comanche 4x4 with an AMC 4.0 straight six with a Aison 4 speed. I power washed it a while back and SEEMS since then it shifts at 3000RPM. From first to second and from second to third 3K. 3-4th is as normal. No bucking or jerking. From what I gather it can be a few things. A sensor possibly a TPS, or the TCM. I paid 600$ for it and it ran and shifted mint before all this started. I know the transmission itself it good. I've ruled out bad shift solenoids. Don't know how to proceed please give me you're feedback. Thanks. Joe
May I add guys that no start is not the only sign of bad ecu. It can be bad fuel economy, Lack of engine power, hard starting, doing all kinds of crazy things. Lastly if you get a computer from a junkyard for an older car, the computer maybe bad even tho the car starts. ECU fail more than you may think and you may not even be aware that its the ecu. I work for a company that test and rebuild ecu.
Hey quick question after getting code 1294 my 97 xj won't start and if it does it shuts off after a few seconds... any idea?? Please, it's my only ride to work
Before I reset my ECU (94 Grand Cherokee) I was getting codes 12 (I know that one isn't a problem) 27(bad injector driver) and 14 (MAP sensor voltage too low or high) but I'm still having it die occaisonally after ignition, at idle, or when driving. In addition, it will lose all power (in the drivetrain only) occaisonally when under load and come right back. I've reset the ECU and the only codes I'm getting are 12 and 55. DO you think it's the ECU in my Jeep?
Was hopin you could help me out a bit my pcm went out 1996 4.0 the manufacturer says i have to have it reset and all this but they cant do it can you install a junkyard one
I have a pcm from my 1998 cherokee classic I took out the screws but cannot get it open any suggestoins that don't involve shooting it or useing a hammer?
Hey Matt! GREAT VID!.....I ask you: does the ECM has anything to do with the cruise control on a 1990 Cherokee, 4.0l, automatic trans? I love my Pioneer....but the Cruise just blinked out.
Matt , ya do a greate job of simplifying almost every procedure, I have been dealing with a shift issue, 3rd to Overdrive lockout. Checked the TV , shift linkage adjustments and pulled the power to the tcu, still no overdrive. I suspect the od lockout solenoid to be faulty. I do know there are other factors the tp sensor and one other. 96 cherokee xj, 4L h.o. .. any suggestions
Should I take out the PCM before shooting it? And Was is one shot then test then three more and try again. If I don't own a gun will AutoZone shoot it for me?
Mine just went out, it was reading codes 11, 111, 112, 116. The first two are system ok....dunno why it read 2 trouble codes. Hooked up a 4.0 PCM and was able to get codes off my scanner where the old PCM I wasn't able to read or recover codes easily. It's been in the truck since 92. So they don't last forever.
Hey guys, I REALLY need some help. I have a 1999 xj 4.0 4wd. A month or so ago my jeep started chugging and stuttering until it stalls out. I got a code and it was the O2 sensor. so i pulled it out, and it worked fine. fast forward a few weeks i replace the bad sensor with a brand new sensor (both up stream and down stream.) same problem again. so right now I am running it with the engine light on and the o2 sensors out. PLEASE HALP
OK... 97 sport sat for a few months, got start ups and yard trips, and out of the blue a dead (less than a year old) battery. Jumped it just fine but as soon as the cables came off all hell broke lose, chugging and running rough, speaker feed back, jumpy gauges a few other things until death and unresponsive. Does this sound like an ECU or a major fault elsewhere? Just want to know where to start thanks
hello I have a cherokee xj sport 1998 2.5 TD, this limited does not pass the 2000 rpm, can be the ecu ???? also smoke when I accelerate, greetings from Argentina!
when he starts the motor from under the hood at 2:42 it looks like the coil wire is sparking to the heater hose. weird. and if the engine refused to run in the 'on' position, but runs in 'start', that leads me to thinking the ignition switch is bad.
mine is sealed how can i check the curciut...also thing like my lights ,blinkers,and sometimes my check engine light would alluminate but throw no code when i check it....recently my 99 ram was running like shit didnt throw any code to find out the crank sensor was bad ...i guessing its the pcm...i checked it with my mac tools scanner...couldnt read it though my cousin who had a bigger better scanner at ammco not sure how he know but his scanner was able to figure out wat was wrong...so im guessing the pcm is bad
hey guys so i have a 94 jeep grand Cherokee 5.2 yes i know its shity motor but i just replaced the ecu and it still wont start what could it be ??????? anything helps thanks ..
I've got a 95 XJ, my check engine light does not illuminate at all bulb is good, cant pull codes via key method, was able to in the past. On petrol it has all of a sudden lost 30-40% power even more noticeable at low rpm's, it runs great on gas (LPG)(nearly double the power and torque)as the injectors are turned off, but on petrol has all of a sudden become awful, really hesitates down low and lacks heaps of power. any ideas, i'm suspecting a faulty ecu... new HP ported polished head from heavy duty casting, edelbrock roller rockers, exhaust and updated non pollution intake, new plugs, leads filters, cap,rotor,coil, ... any ideas welcome\
hmmm, not sure bud. If there is no check engine light its not going to have any codes. Here in the states we only run on petroleum, no propane, so I am not sure how that works but I wonder if you could have a clogged catalytic converter?
BleepinJeep just an update, so, purely a coincidence that the CEL light had blown around the same time my issues started, replaced it and was able to pull codes(went to a few places to get the codes read and no body has the correct connector). Has thrown a lean fuel code, I was starting to lean toward a fuel pump issue, drives even worse now. Mash the throttle and it bogs and backfires and carries on. Used to spin the 33 muddies when kicked hard in the guts. Gonna grab a fuel pressure gauge tomorrow and test. Cheers for the reply. Love your videos, there aren’t a whole lot of xj’s left in Australia so it’s hard to get good advice here.
pretty sure the ECU was stuffed as soon as you put a bullet into it, but reality would tell you to just buy an OBD2 scanner or just get a paperclip idf it is the old OBD system and bridge the two terminals, it takes 5 minutes with the scan tools to find out if your computer has had it
His casual voice after shooting the ecu.... perfect
That was freaking awesome! hands down the best diagnostics I've ever seen, I plan to utilize that technique in the near future.
Nice! Love your solution - there's nothing like a 1911 for "troubleshooting"!!!
Helping a buddy troubleshoot the stalling problem with his Jeep. This video recreated exactly the behavior of the vehicle (turn over while engaging starter then stalls out w/o starter kicking) and confirmed what I had read on forums about it maybe being the PCM / ECM / ECU. Thank you!
this fucking guy is the best I've never seen something so simplified. Had to favorite this one. LOVE IT!
Thank you for this. I've been researching how to diagnose my ECM for over an hour and no one else has showed opening it up and what to look for INSIDE it. THANK YOU!
Unfortunately I do not own a pistol so I am not able to recreate the shorts, but very helpful! Hahaha
By far one of the best Bleepin Jeep vids I've watched. Gonna take apart my PCM when I get home now!
Instructions unclear, there are now 12 holes in my driver's fender and the engine is leaking coolant, and oil. How do I remove the virus from engine?
No 1/2 gas, 1 match, and watch it burn!
I can't stop laughing.
Tears coming to my eyes..
Laughing uncontrollably.
Best comment of this generation.
Thanks for the humor.
Put a mask on the front bumper cover.
LMAO
Wow, that was a good one. Especially adding some bullet holes & seeing how it made the jeep barely run & then not run at all. Nothing beats experience & that is what your sharing so we don't have to bang our head against a wall trying to figure out a problem. Thanks.
thanks for the awesome comment! glad i could help
Best computer trouble 'shooting' video 🤠👍🏼
you have come a long way.................
Also thank you for the help. I had a problem with a harley in a fire and you just confirmed my suspicions.
A very good video here explaining and showing examples of some of the things that causes ECU problems.
THANK YOU, That settles it....now to find a junk yard to swap out my recently discovered defective ECM.....no im no mechanic....but I always like to be a little informed before I take my 2004 GJC to the shop. Good Info man
Damn I didn't know shooting holes in your ECM/ECU would cause the engine not to start. Thanks for clearing that up. L☺L
Sometimes it might fix it as well
BleepinJeep have 95 grand 4.0 stalls out still drivable revs up and down no check light herd around u can loosen screws on the pcm job cause they josh it up should i give it try have u urself had same prob iev had four of these things wont go back to anything else good runners let me know bud thanks
Bro what does no bus mean? My gauges aren't working either, I just changed my crank position sensor
Ain't no Norton gonna fix that virus
lol
+Michael Hodges lol
Michael Hodges Norton can't fix shit anyway. all it does is slow shit the fuck down
Norton is like a virus in itself
sorry, my best guess would be the 02 sensor, have you replaced that?
I bought the Jeep high performance computer for my '89 mj when the Chrysler dealers had only 12 or 13 left in their inventory. Fortunately i had removed it for troubleshooting prior to it catching fire and burning. I now have it in my '90 mj
You are freakin' brilliant. 'Installed a virus'...nice.
i laughed hard when he said he just installed the virus lmao
Virus comment cracked me up.
If my ECM is bad, will the car temporarily start if I spray starter fluid in the throttle body? That is what my car does.
Mine too...do you know why is that? Is it because you are making the explosion for the ignition?
sounds like it may be the fuel pump. or maybe the fuel pump fuse or relay.
CPS
I'm not a jeep guy but it would make sense that this things can take a bullet and virtually keep goin. That's pretty cool
Ma dude lol the best educational video i hv ever watched *.*
You are the Jeep world's Mr. Rogers.....
I would suspect it just needs a tune up. New spark plugs w/ correct gapping. New cap and rotor, new spark plug wires. If that's not it then my second guess - a vacuum leak.
I wish cars still have carburetors and mechanical ignition systems, they were easier to fix and diagnose. I miss the days with things were simpler.
You have romanticized nostalgia for old cars. They didn’t work well. Cars didn’t Harley last 100k.
How do you know the junkyard ECU is good? Open it up and look for shorts?
Buy it and test it. And its broken, return it. Most junkyards have a 30 day return policy
Nice choice of the 1911. If you're going to shoot holes in things they might as well be big ones!
Thanks for the concepts you have contributed here.
wow, could be a ton of things... Is the 86 not carbed?
You will never do that if you knew what a used ECU cost in Denmark, I am crying now ;))
new ones 187 $ in usa
If you ever need one I've got a shit ton I'm a parts hoarder, would love to come to Denmark, been to Sweden and Norway beautiful place I've thought about moving there skoal brother
I check the computer first with a test light at the coil and then at an injector. You should get a pulsing light at the feed wires. That proves 2 important functions are working. The crank sensor, and the computer. Then I start checking voltage at various sensors. If that is good then likely the computer is good. Symptoms will at that point direct you to potential solutions.
hahahah missed this video bad ass bro you are always my go to guy for xj info thanks a lot bro
Paul from Quebec
That was seriously brilliant man. Thanks!
Made my day a whole lot better 😂
OMG Hi-larious! i didn't expect to learn anything from this video after seeing you shoot holes thru your ECM but was happily surprised when that wasn't the case! it helped me seeing your vehicle still ran even with holes blown thru the board!
I've been trying to diagnose the cause of a U0107 DTC in my car and all the voltage & continuity checks have been normal. I replaced the TAC module so the only thing left that i can think of is a faulty PCM but before watching this i assumed there would be more issues than just the electronic throttle if that were the case. thx 4 this!! it gives me a lil more confidence in replacing the PCM. only prob now is one of the connectors is stuck in the PCM. I've got the other 4 out but I'm almost wondering if the dealership super glued connector A bc I'd just taken the car in for a PCM recall where they put a cheap little plastic piece over it and i wouldn't put it past them to mess it up thinking I'd be forced back there 2 have them repair it
Was that your magazine falling as you drew?
+ymp5000 no, was the holster
BleepinJeep Copy that.

LMAO I friggin loved this goes to the extreme but gets the point across depends where it frigged up is what headaches it will give ya
Good video bad transistor can be repaired with $2 That is the transistor sends power to fuel injectors .
My pcm went out on my 97 jeep zj and cost me 220 dollars and a core charge also my coil shorted out and shorted my pcm out and ihad to get a new one if u get a used one u have to get it flashed to ur vehicle or it will not run right took me months to figure out why my pcm went so if i was everyone with a jeep id go get a new coil before urs shorts out
I have a question. I purchased an 04 Jeep Liberty, less than 24 hours I got a no bus reading on my cluster. Replaced the cluster, BCM, and just replace the ecm.

It's completely dead after starting and shutting off! 😭I'm in such need of help
sorry to hear that... what is the question? what is the dealership saying now, I would take it back and tell them to fix what they broke.
Get the old parts back and reinstall them.
If you have or had security system check for lockout.
I have a 84 jeep Cherokee 4 cylinder I did the nutter bypass running great so with that said is it possible to remove the computer?
AS happy as shooting it would make me, it blows my mind the wiring lenght in the driver door. See i have discovered the alarm runs thru it and when my1985 cherokee has a stalling problem its because of those wires..i have every one nail polished to color. code..and when the drivers door gets swung open by wind or me the stalling atarts again..I love the video ..Thanks
well you didnt say what kind of vehicle you have but the older cherokees are under the dash, big silver thing. And the newer cherokees are on the left fenderwell under the hood, black. Just unplug, unbolt, and put the new one in.

First I would start with a good battery, if under a year it should have full replacement. Then try again and let us know where you stand.

"Let's give it a shot now and see what happens"... you just gave it 4!
You gave it your best SHOT now let me take a STAB at it
"Lets give it a shot now, see if it works." he says after putting like 5 shots in it.
not sure if you still check this but if i go get one from the junk yard for my 99 will it work? i thought they had to be programed via Vin
best video of all time.
Two thumbs up. R.I.P Roger Ebert.
that was the holster but yeah, I just went with it.
May I add guys that no start is not the only sign of bad ecu. It can be bad fuel economy, Lack of engine power, hard starting, doing all kinds of crazy things.

Good job on the videos bub!
Was hopin you could help me out a bit my pcm went out 1996 4.0 the manufacturer says i have to have it reset and all this but they cant do it can you install a junkyard one
I think the jeeps been diagnosed with the same gun a few times before 😆
Damn. I'm impressed. And your (really cool) video answered many of my questions. Will check my ECM for bullet holes. lol! Thanks. Subscribing now.
I have a pcm from my 1998 cherokee classic I took out the screws but cannot get it open any suggestoins that don't involve shooting it or useing a hammer?
Does the part number on the pcm have to be the same as the original one . Both are 1999 but different part numbers
Not if I have anything to say about it!
Dude that was really funny. Thanks for the info.
Hey Matt! GREAT VID!.....I ask you: does the ECM has anything to do with the cruise control on a 1990 Cherokee, 4.0l, automatic trans? I love my Pioneer....but the Cruise just blinked out.
Jeep can make a straight 6 that will run 300K without a hitch but can get the dome light to turn on without stalling the engine out at idle.
Very helpful very helpful explained everything
Matt , ya do a greate job of simplifying almost every procedure, I have been dealing with a shift issue, 3rd to Overdrive lockout. Checked the TV , shift linkage adjustments and pulled the power to the tcu, still no overdrive. I suspect the od lockout solenoid to be faulty. I do know there are other factors the tp sensor and one other. 96 cherokee xj, 4L h.o. .. any suggestions
my 1999 jeep is having parasitic draw on the battery can that happen from a bad eco?
.45 acp is the best for ecu diagnostics!
Thanks BleepinJeep
Good video
Does anyone know if a failing ECM would illuminate the ABS light ?
PASTBETTER it could yes, but I test the sensor first
What could cause a 1996 jeep grand Cherokee Laredo to stail while driving or at a red light
Ed Chambers the answer is a drunk driver.
this is the best thing i have ever sAW
Should I take out the PCM before shooting it? And Was is one shot then test then three more and try again. If I don't own a gun will AutoZone shoot it for me?
Bad ass! Cool way to troubleshoot dude
Perfectly said. Great video
Please show where this part is and how to swap... for the novice! Thnx
If I have a 2000 IL6 grand Cherokee can I go to junk yard and swap one as well?
Mine just went out, it was reading codes 11, 111, 112, 116. The first two are system ok....dunno why it read 2 trouble codes.

mine is sealed how can i check the curciut...also thing like my lights ,blinkers,and sometimes my check engine light would alluminate but throw no code when i check it....recently my 99 ram was running like shit didnt throw any code to find out the crank sensor was bad ...i guessing its the pcm...i checked it with my mac tools scanner...couldnt read it though my cousin who had a bigger better scanner at ammco not sure how he know but his scanner was able to figure out wat was wrong...so im guessing the pcm is bad
Awesome shirt, where can I buy it??
hey guys so i have a 94 jeep grand Cherokee 5.2 yes i know its shity motor but i just replaced the ecu and it still wont start what could it be ??????? anything helps thanks ..
awesome video man, I love it
my 86 XJ is running very very rich, ive replaced all the sensors that i could think of that would work with that. ECM next?
I've got a 95 XJ, my check engine light does not illuminate at all bulb is good, cant pull codes via key method, was able to in the past. On petrol it has all of a sudden lost 30-40% power even more noticeable at low rpm's, it runs great on gas (LPG)(nearly double the power and torque)as the injectors are turned off, but on petrol has all of a sudden become awful, really hesitates down low and lacks heaps of power. any ideas, i'm suspecting a faulty ecu... new HP ported polished head from heavy duty casting, edelbrock roller rockers, exhaust and updated non pollution intake, new plugs, leads filters, cap,rotor,coil, ... any ideas welcome\
hmmm, not sure bud. If there is no check engine light its not going to have any codes. Here in the states we only run on petroleum, no propane, so I am not sure how that works but I wonder if you could have a clogged catalytic converter?
BleepinJeep just an update, so, purely a coincidence that the CEL light had blown around the same time my issues started, replaced it and was able to pull codes(went to a few places to get the codes read and no body has the correct connector). Has thrown a lean fuel code, I was starting to lean toward a fuel pump issue, drives even worse now. Mash the throttle and it bogs and backfires and carries on. Used to spin the 33 muddies when kicked hard in the guts. Gonna grab a fuel pressure gauge tomorrow and test. Cheers for the reply. Love your videos, there aren’t a whole lot of xj’s left in Australia so it’s hard to get good advice here.
A pcm is a power control module, AKA it means it is the ecu and tcu in one unit. An ECU is different than a pcm.
pretty sure the ECU was stuffed as soon as you put a bullet into it, but reality would tell you to just buy an OBD2 scanner or just get a paperclip idf it is the old OBD system and bridge the two terminals, it takes 5 minutes with the scan tools to find out if your computer has had it
Funny . I like the simple approach to problem solving. Lets ask Hillary about pay for play donors to her foundation with this approach.
Thanks for staying on topic.
