hey ivan, I had something similar with a dodge 4.7 enging. long story short there are about 15 ground wires going into 1 terminal behind the right side head. crazy things were happening!!! fixed it the eric o way... with multiple eyelids
Well, if the problem I'm having is going to involve the gastank somehow, I do try to bring in the car with less than reserve remaining, as I assume that makes the technician's life easier, because there is no excess amount of fuel in the system (correct me if I'm wrong there and you lot would rather wrestle with a full tank). Otherwise I'll leave it at whatever it's at.
Is that a win? Uhm, let's see. Your working in another state, in the cold, clearly rushing, on a van with no gas, and also making a video of it all. Hell yeah, Ivan, that's a friggin win! You are a beast!
Nice diagnosis Ivan! Scope for direction and nothing better than the visual aspect of a test light or test bulb to load the circuit. Looking forward to see what 7.3 is.
I have learned from the pros that sometimes backprobing causes more damage than a fine piercing probe! The connection to the meter is also more reliable with the piercing probe, making for a more accurate diagnosis. :)
Sounded like you were diffusing a nuke there for a minute. Diagnosis was great, as usual- but the quick and dirty repair isn't your style. I know that place must have a huge caseload- so you patch it up and ship it like a MASH unit.
When I see one of those yellow school buses I flash to Dirty Harry and Clint Eastwood jumping onto the buses roof to waste Scorpio and save the school kids.lol .Another smart diagnose Ivan.
Great job Ivan! Real world timely fixes. Who wants to pay for a search that may not be conclusive when a positive real world fix will out last the vehicle?
Very good diagnosis Ivan, some people might say why not to fix the wire instead of by pass, well on the real world lots of costumers don't even want to pay for the diagnosis! So lets not spend time that we will not charge for! Either way the repair is done very well. I have costumers asking me if the diagnosis is included on the repair!! LOL, my answer is always, so If the repair is just a broken wire (and toke me 2 hours to find it), should I charge you $5?
Maic Salazar bypassing known faulty 12v wires is just dodgy and asking for trouble. that loom could be rubbed through and other wires affected soon which could arc and have a bus fire loaded with kids? love his videos. but cant agree with this repair.
Keep in mind that this is a modern vehicle with fuses, which will blow way before anything arcs and catches on fire. The only wires you really have to watch out for are the main power feeds to the starter and alternator, plus the battery posts. I believe that is how ScannerDanner's Jeep caught on fire...the naked positive battery post possibly shorted to the hood latch.
I appreciate what you are saying.but have been installing stereo systems for 20+ years. and have seen and also caused a few wire arcs and meltdowns that have melted/burnt interior pieces etc. and they were all fused appropriately. anyway love the channel Ivan. yourself and south main are awesome!
Matthew Collins the bong noises are starting to go away. there is push button start, so no keys left in the ignition. then there are auto headlights, so leaving your headlights on after stop no big deal. the only beep I have heard from my car is when your don't put your seat belt on and you hit 5mph.
So it dings to tell you the keys are in the ignition? How weird. I've never had a car that does that. (Over in the UK). I think it would drive me batty.
Matthew, on cars sold in the U.S. with a standard transmission you also have to push the clutch pedal down to make the starter work. this "security feature" throws a lot of (european) people off the first time. :-{
I do not understand why PCM/ECM have monitors on sensors and acuators, like sensor line high/low voltage etc, but not on PCM/ECM power and grounds? Electronic components are cheap and you could easily generate codes for missing PCM/ECM power and grounds. This would save a lot of time, no need debug anything else in or out from controller, you would already know what power / ground you need to fix straight away from the code.
The entire point of having an ECM in control of things is not to make our lives easier, it's only there to guarantee the EPA that emissions are being complied with. You get no self diagnosis circuity on non-mandated issues. Price point is already sky high. In a perfect world, your points are spot on, just so happens it's not a perfect world. AND as Ivan has corrected even pessimistic me, without these failures -- he would be looking for another line of work.
In a sense yes, but since 1980's in 20 years we now have live data, hundreds of PID's and way more info which makes fixing things way easier than the blinking led on K-Jetronic driver box. From my point of view cars are now easier to fix than 20 year ago. More complex yes, but more data and diagnostics in the box. Thus $2 six line AD -converter added to the SOC might not take the whole business away, since adding it to the sensors and actuators did not ruin the business years ago? Just my $0,02
I've seen "PCM lost power" codes. This was on a Cummins with jerry rigged "semi truck" battery terminals that the owner kept neglecting to fix properly lol.
Ivan, Nice direction and diagnosis ! I'm sure you could of given the customer the option of replace/repair of the harness if the decision was yours to make but hey real world fix for real world scenario !
I might have missed something, but how did you go from noticing a problem with fuel injector control and fuel pressure while ignition control waveform looked good to figuring out the problem was with pcm ignition power feed?
PCM wasn't storing any trouble codes, so wasn't likely to be an input problem. Only other things to check are powers and grounds! What direction would you have taken?
what lead you to check powers and grounds at the pcm? experience? or the loss of injector control? did you scope the cam and crank sensors and seen they were good then went to powers and grounds. it was a good diagnostics. I was thinking maybe it was a fuel cut from the theft system. I woulda checked the enable or disable pid
If it was an intentional fuel cut, there would have been a trouble code stored like "VTD fuel disabled" or something. But having no relevant codes, and seeing the ignition coils maintain a consistent control throughout the stall, told me the CKP sensor was OK.
I had a similar issue w/ a 13 silverado 1500 4wd 5.3. It was brought in for a CEL, starting problem: start stall ( not stated on RO), lack of power/misfire a highway speeds. Scanned for codes and there was a p0101, p0102, p0171, and p0174. Okay possible MAF sensor. Look at freeze frame, Idle , warm, stft like 20%. ( i need to document my readings as I go). No common issues per troubleshooter, tsb, google, etc. Okay look at MAF data and it's all 0. even in generic. I cleared the codes and instantly I was then dealing with a start stall. couldn't get the truck running pressing the accelerator or anything. Disconnected the MAF same. Vacuum goes up the 20" then falls w/ engine, rpm goes up and down with stall. Added brake clean to keep it running, with brake clean able to keep it going, but then started running like total crap. vacuum 10" steady. Died out, Fuel pressure consistent. 50-60 during stall. It sat for maybe 10-15. then started up fine ran great, vacuum 20" fuel pressure 50-60 doesn't drop on a snap throttle. this is as far as I got. All the variable threw me off. Trying to understand your logic. coil control and injector control eliminates cam, crank, and tells u if your dealing with fuel or spark? the injectors dropping out being a pcm issue? could it be because of a sensor that's giving an incorrect signal cause the pcm to kill injectors? Logic in the pcm wouldn't kill the fuel from a bad MAF sensor would it?
Great use of incandescent bulb test light, but why would a wire go bad in the middle? Overcurrent is only thing I would think. If you splice in a new wire of same gauge won't whatever burned the old wire burn the replacement? Should check and write down run current of replacement wire, in case bus comes back, and also if you see above 3 amps start to think about what's causing high current draw.
Wish I had an answer for you. There were no intermediate connectors between the fusebox and PCM to narrow down the problem any further. I assume green crusties did their magic somewhere in the middle :)
12volt Tech yes, it would be a hack in certain situations but this bus is a tool to get people from a to b and back. why cost the school system more money just to restore a wire or connection to factory condition when this does the same thing.
It's a hack because when dealing with wire bundles - abrasions, pinches, meltdowns, etc don't always result in a single surgically affected wire. Thoughts of whatever calamity that could happen due to a bus suddenly stalling aside, not verifying the actual cause to ensure that other wires in the bundle aren't split and about to short or corrode is just plain negligent.
Me too. The vast majority of a vehicle's wiring is difficult if not impossible to access. So I'd say for almost 75% of open wires you need to run a bypass unless you want to take apart half the car (bus truck etc.). At least you're not putting in an after-market part!
I did do a wiggle test and visual inspection on the entire harness. There was no obvious damage. Now if you are bent on finding the exact location of the fault, then you might have to open up the harness in several places, which is actually MORE likely to damage it than leaving it alone and just bypassing the bad section. Furthermore, my bypass wire was wired to the original fuse, so not sure why you think there is a risk of "meltdown"?
Great fix but just be warned that bypassing a power wire like you did may be a problem if something else feeds off that wire you bypassed. I did the same thing on a 5v ref for a throttle pedal that had one of the two 5v ref were bad. The schematic clearly showed 2 separate wires going to the ecm so I cut the bad wire and put a jumper on it and turns out that both of my 5v ref came from only 1 wire and when I cut it I didn't have power on the other. Short story is just be careful How do you like the touch screen laptop for the pico?
No it was a bad ecm power wire, about the pressure drop i dont know probably since the pump relay was controlled from the ecm so a bad 12v wire could not have total control of it.
On this type of. Fix where you add wire. To by pass trouble spot quicker and and faster to fix This save service time for customer and less expensive bill.
Ivan pretend this question makes sense. LOL Ok if you're suspecting a ecm ground would a voltage drop from the data link connector at the ecm grd. pin to the battery grd terminal show a bad ground. No laughing......
Excellent question, Steve! It depends on the actual vehicle. Sometimes ECM grounds are all tied together. Sometimes grounds for high-amp drivers are routed separately from sensor grounds. Wiring diagram is key.
I think its more like a damn DINGER.! MAN, 30 seconds into diagnosing, I would have fixed that damn dinger ding ding.! Congrats Ivan for staying focused somehow on the real problem and getting her all fixed up. Now the wheels on this bus can go round and round once more. (: Cheers
If I need to work with the doors open and have the key turned on, I close the door latch with a screwdriver and plug in the driver seat belt before I even start.
No Child Left Behind -according to President Bush ! That was probably the only bus in Staten Island, that day, without a child left on it,as much as it happens
Funny. how customer. doesnt want to spend more than. X amount of time on diagnosis when the customer is the school ( or maybe a school bus company ) . Schools throw away more money than drunken sailors. if these cheap bastards dont want to spend more than $5 to find problem then charge $5 for repair and $750 for processing shipping. and handling .........,. L. O. L
Sorry Ivan. Totally lost me on the real purpose of this video. It's a school bus. Carries children. You found a wiring problem. You jumped a symptom. Bandaid it. Did not show doing a continuity check on said wire. Did not eliminate suspicious wire from circuit. Hope it doesn't cause issues down the road. Are you saying this wire is partially broken? I know it's a field fix and pressure is present from your cheap ass customers but, do it right and do it thoroughly. The video is 13 minutes which does not tell me how much time you spent on it. Like 2 or 3 hours. Between that alarm constantly going and your jumpy thoughts did not help me understand what you were proving. Either GM has wiring and ground issues or your just showing off. Won't stop me from watching you videos.
Actual diag and repair time was at least 2 hours. Continuity check unnecessary. Bypass wire DID eliminate suspicious wire from circuit...that's the whole point of a bypass! It's a permanent fix, not a band-aid. Time constraints definitely cut into video time and quality, but I try to show the key points :)
motoYam82 Wow, Evan I'm truly honored you took the time to respond. Don't get me wrong, I've learned a lot from your videos and I'm amazed how you get down to the actual circuit causing the issues. I love diagnosing electronic and electrical problems. It was interesting the way the light was going dim. Kind of scary. I guess the wire was going all over the place and you chose to bypass it. All I'm saying is, things were not that clear to me. Keep them coming my friend. You and Eric O are my hero's. God bless, and I mean it.
Sir, you will never "bore us with the details".
hey ivan, I had something similar with a dodge 4.7 enging. long story short there are about 15 ground wires going into 1 terminal behind the right side head. crazy things were happening!!! fixed it the eric o way... with multiple eyelids
That was fun. It cracks me up when customers give you a vehicle and the gas gauge shows empty.
wyattoneable cheap tight bastards....
Cars are usually on empty when they come in. Unless the tank needs to come out. Then they're full.
truth.
Well, if the problem I'm having is going to involve the gastank somehow, I do try to bring in the car with less than reserve remaining, as I assume that makes the technician's life easier, because there is no excess amount of fuel in the system (correct me if I'm wrong there and you lot would rather wrestle with a full tank).

Is that a win? Uhm, let's see. Your working in another state, in the cold, clearly rushing, on a van with no gas, and also making a video of it all. Hell yeah, Ivan, that's a friggin win! You are a beast!
The way the wiring on these school buses is hacked up, Ivan's fix is very appropriate.
Great diag Ivan. I see what you mean about the Staten Island Test Light workout!
'No Load Pro's were harmed during the making of this video'
HAHA Load Pro.
I have not finished the video and I already like it ,you are good Ivan. Thank you every time I learn something new.
Great work Ivan.
Nice diagnosis Ivan! Scope for direction and nothing better than the visual aspect of a test light or test bulb to load the circuit. Looking forward to see what 7.3 is.
nice find
was in the wire , or the fuse connection?
You pierced a wire! You violated it and could be brought to prosecution! According to Dan Sullivan anyhow. Good video and diagnostics as usual.
I have learned from the pros that sometimes backprobing causes more damage than a fine piercing probe! The connection to the meter is also more reliable with the piercing probe, making for a more accurate diagnosis. :)
And i am sure the pros you are talking about I as well would respect their input on the matter! Thanks Ivan!
The proof in the pudding, IS IN THE EATING!
Great diagnosis, as usual. Keep up the good work.
Sounded like you were diffusing a nuke there for a minute. Diagnosis was great, as usual- but the quick and dirty repair isn't your style. I know that place must have a huge caseload- so you patch it up and ship it like a MASH unit.
When I see one of those yellow school buses I flash to Dirty Harry and Clint Eastwood jumping onto the buses roof to waste Scorpio and save the school kids.lol .Another smart diagnose Ivan.
My initial thinking was a VATS issue, but good find on that PCM feed wire!
Great job Ivan! Real world timely fixes. Who wants to pay for a search that may not be conclusive when a positive real world fix will out last the vehicle?
Very good diagnosis Ivan, some people might say why not to fix the wire instead of by pass, well on the real world lots of costumers don't even want to pay for the diagnosis! So lets not spend time that we will not charge for! Either way the repair is done very well.

The wheels on the bus go start and stall
Why do American cars make so many bong noises? Don't you find it a bit annoying?
Matthew Collins the bong noises are starting to go away. there is push button start, so no keys left in the ignition. then there are auto headlights, so leaving your headlights on after stop no big deal. the only beep I have heard from my car is when your don't put your seat belt on and you hit 5mph.
So it dings to tell you the keys are in the ignition? How weird. I've never had a car that does that. (Over in the UK). I think it would drive me batty.
Matthew Collins and in the USA you need to push the clutch to start the car. Too bad if you stall on a railway crossing...
Matthew, on cars sold in the U.S. with a standard transmission you also have to push the clutch pedal down to make the starter work. this "security feature" throws a lot of (european) people off the first time. :-{
Becuase most people are idiots. It dings to let you know to put on your seatbelt, your keys are in the ignition, there's a door open. It's annoying.
Ivan your shaky video camera videos are great keep them coming thank you for your time making these videos👍🏻👍🏻👍🏻👍🏻
Hello... how did u make your test light u used..... with your test leads
Hoping to hear back from u

looks like the school bus gave you a learning curve.

Well I would definitely chase the MAF codes first! You should at least be able to track down why it's reading 0gm/sec all the time.
motoYam82 dealing w customers and service writers they want to lump all the symptoms together and not being paid enough time for diag.
awesome job
That "keydinger" is crazzzzzzy :-)

Nice! As always
what led you to voltage drop? my next step would have been a crank sensor
ignition coils were firing consistently during stall, so not worried about CKP sensor in this case...
Damn your hella smart great diagnose
Is there an anti-theft device, because with some systems it works like this.
Oh, I was to early sorry. Anyway a nice fix Ivan.
door alarm is very very
The school bus need a whole complete tune-up basically and vacuum lines check😭
The proof is in the pudding! ! nice 👍
Well that ding isn't annoying at all, nope not one bit.....
you have no idea...I was there, and it didn't stop until you took the key out. I had a hard time hearing myself think!!!
Hack fix. But probably what I would've done.
Why do you say its a hack job? Sometimes it's better to eliminate the problem wire, Ivans fix will more than likely out live the bus.
12volt Tech yes, it would be a hack in certain situations but this bus is a tool to get people from a to b and back. why cost the school system more money just to restore a wire or connection to factory condition when this does the same thing.

How do you like the touch screen laptop for the pico?
So fuel pump was dropping out due to faulty PCM control feed
No it was a bad ecm power wire, about the pressure drop i dont know probably since the pump relay was controlled from the ecm so a bad 12v wire could not have total control of it.
armando nika
Yes I agree, I just wasn't quite sure why the fuel pump itself was faltering. Two different symptoms related to the same prroblem.
Exactly. Once PCM lost power, it couldn't keep the fuel pump relay energized so we lost fuel pressure as well!
On this type of. Fix where you add wire. To by pass trouble spot quicker and and faster to fix This save service time for customer and less expensive bill.
Ivan pretend this question makes sense. LOL Ok if you're suspecting a ecm ground would a voltage drop from the data link connector at the ecm grd. pin to the battery grd terminal show a bad ground. No laughing......
STEVE ROB ECM may have more than 3 grounds
huggybryn39 I think I remember hearing the grounds are all tied together in the ECM. Might be wrong .
STEVE ROB With O2 sensors working with low amps and voltage you may require a separate ground for the return.
Excellent question, Steve! It depends on the actual vehicle. Sometimes ECM grounds are all tied together. Sometimes grounds for high-amp drivers are routed separately from sensor grounds. Wiring diagram is key.
yes! school bus. same one I rode to school
please shut off that damn beeper! Good fix though. This series should be called jumper wires on Staten Island.
I think its more like a damn DINGER.! MAN, 30 seconds into diagnosing, I would have fixed that damn dinger ding ding.!
Congrats Ivan for staying focused somehow on the real problem and getting her all fixed up.
Now the wheels on this bus can go round and round once more. (:

The short bus 🚌😂
BONG, BONG, BONG, BONG, BONG, BONG, ping ping ping ping
maybe in the past someone poked a hole in the wire with a test light moisture got in cause corrosion
Now why would someone ever do that??
Great video, please shut that crazy beeping off during video's.
Trust me I really tried, but the stupid school bus would NOT SHUT UP hahaha
Not as "satisfying" as finding root cause, but it get the customer back on the road !
I would go iac 😀
Hey, did anyone else see the sleeping child in the last row?!!
No Child Left Behind -according to President Bush !
That was probably the only bus in Staten Island, that
day, without a child left on it,as much as it happens
there's your problem lady
Funny. how customer. doesnt want to spend more than. X amount of time on diagnosis when the customer is the school ( or maybe a school bus company ) . Schools throw away more money than drunken sailors.
