Buick LeSabre: Customer Replaced ECM Now A No Start, No Lights, NO NOTHIN!

In this video we have a look at a Buick LeSabre that the customer replaced his own ECM on. He was told by another shop that this would fix his low power complaint. Now he had to have the car towed here because it will not crank, and NONE of the functions of the car seem to work. It does not take long to find out the whole story! As we have learned many times before, there is allllllways more to the story. -Enjoy!

Johny Harbinger techs and mechanics are two different people as I see it.. a tech is less hands on..techs mostly do diagnostics. mechanics are the ones getting dirty and physical with the vehicle. Both should know each other’s job and be able to do each other’s job. Just specializing more one way than the other. Like Eric O here, Eric is a mechanic, but he also does the tech’s job just as well and as easily. He just specializes in using his brain in more of a physical manner aka physically tracing down issues, opening things up and finding problems to solve that’s what makes him more of a mechanic.

Eric, I used to own a Buick like this one and had trouble with the cigarette lighter. While pulling the fuse out of the fuse box I noticed the same thing you noticed. There were three female receptacles on the fuse box for a two pronged male fuse. According to the Buick booklet that was in the glovebox, 24:14 it states that if you put the fuse in the left two female receptacles the lighter works only with the car running in the ON position. If you put the fuse in the two right female receptacles the lighter will work with the car turned in the OFF position. I absolutely love your channel and have learned so much from you watching it all the time . God bless you and your family.

Not disputing your take. However even though I enjoyed what I did, I gotten tired of the typical shop politics, flat rate pay, overloading of technicians( too many technicians and not enough work) causing for a CUTTHROAT environment in which technicians fight over jobs in order to attain a diecent paycheck. Plus too many bosses do the aforementioned plus give reasons as to why they can't pay the proper rates. Eventually in most cases you find out why over time listening to conversations. It's either they have too many toys, and extramarital affair, a gambling problem, or a very expressive lifestyle, take your pick. Technicians have many of pressures, along with the huge investment in tools, constant training to keep up with the rapidly changing automotive systems. Most technicians like the profession. Although it's the excessive BS that comes with is to why from a techs point of view professionals are leaving the field, and it will continue until the standards in the industry change.

Completely speechless. Another shop caused the fuse to blow so it wouldn't start because they misdiagnosed the car and tried to put another ECM in the car, which was the wrong ECM all for the real problem of a bad cat and possible bad starter. WTH! Then when they realized they screwed the car up royally, they push it off to Eric O to save the day. You wonder why we love this channel so much? Just take your car to one of THESE OTHER shops for the day and see what you get back in return. Eric O can't save everyone's car from every other shop. This Buick owner in my opinion got lucky today. Awesome awesome video.

[@mrdiplomat9018]

Mr B It’s diagnosis, not prognosis I think. Prognosis is what the doctor tells you after he runs tests on you‼️

[@mrb1864]

I used prognosis intentionally . You diagnose the fault, your prognosis would be whether you think the vehicle would run perfectly after your diagnostics findings and repair recommendations , indeed more common used by doctors than in this case mechanics but fun to use :-) ...

[@flinch622]

Hammering home an electrical connector is complete luddite territory. Connectors are keyed differently to protect systems from pin layout differences - I suspect the wrong computer may have been what blew fuses. Why anyone looked at the ECM in the first place is beyond me. If I'm RPM limited [video looked like he couldn't get past 4500 rpm], one of two things has happened: fuel curve is truly out to lunch, or the engine isn't breathing right. That leaves MAF sensor or the CAT as things to check first. Last time I had a CAT clog up on me was due to a turbo seal going out/oil vapors fouling it up.

I suspect the other shop thought it was in Limp Home Mode because of a 'bad computer'... This owner shouldn't even be changing a distributor cap let alone a computer if doesn't know about guide pin differences... square peg in round hole, etc...

Funny thing is when the passlock security system activates it shuts the fuel pump off. Disconnecting the battery clears the code..Real culprit was the BCM...

I remember when I was a kid, my father would go to a local McDonald ( with me in tow ) and there was a guy who rented a small 2 bay garage to work as a mechanic. One day some guy comes in and complains very loud to the mechanic guy about how he paid money for a repair that didn't correct the issue. After the customer left, mechanic guy sits with the rest of the group and said "What's his problem!? If that didn't fix it, all that means is we have to try something else! That's what I tell people. If you have a problem, and you change something, and you still have the problem, that means it was something else!" And the guys in the group all agreed as if praising his gospel. Except that the guys that know this mechanic wouldn't visit him for anything other than for brake pads or tire rotation. Anything else and even his own friends would take their cars to another shop.

[@MrFriendsfirst]

ace When a car gets upwards of 200 thousand miles, why complain about new parts?? There gonna wear out anyway and the money you save not paying 200 an hour to have it looked at will make up for it.

Theres only so many parts, eventually youll fix the right one, and my best guess is usually pretty close anyway.

I was a car mechanic and took those skills to industrial machinery...the logic of troubleshooting is the same. It's a learned skill, step by step, using tools, diagrams and experience. Great job.

This is what happens when you don't compare the old part with the new one. You did a great job on this car! I really don't like fixing other peoples nightmares but sometimes you have no choice. :-)

[@earlestes8649]

Yeah you do, lol 😝 just say no. All kidding aside, my wifey says that’s my problem! I just did a pro bono for a relative and someone had really messed up the wiring on their electric furnace, the wiring diagram wasn’t even close to what it was. Of course nobody knew what or how that happened 😂. With my volt meter the three new elements were only getting 120 volts after moving around about six wires was able to get the old girl running

I wish I knew a mechanic like you good job 👍. I have 2007 Honda Accord v6 3.0 which I take very good care of. It has 180k miles. It runs just like new when I bought it in 2007. The transmission kept slipping it’s an automatic. Mechanics were telling me I needed a new transmission:(. I watched a couple of your videos on diagnostic problems and with a buddy of mine we found that the motor mount was bad which led to the transmission slipping. Man I would’ve been out at least 3 to 5 grand.

Reminded me of days long ago when I was a mechanic. I diagnosed a car as needing a new computer, customer decided to fix it DIY. Couple weeks later I walk into Advanced Auto Parts to pickup some seat covers I ordered. In walks the DIY computer customer who slams an alternator down on the counter exclaiming "This is the third defective alternator you've given me, it won't charge the battery!" As he argued with the parts guy I walked over and said "look, I've seen the occasional defective new alternator but never seen two let alone three in a row. Chances are something is wrong with your car, why don't you bring it by tomorrow so we can check it out for you?" Turns out when he replaced the computer he pinched a wire shorting it to ground. The wire was the one that goes to the battery light on the dash, that wire is used by the alternator for its voltage sense and if grounded or the light bulb is burnt out the alternator will not charge! I think we charged him like $45 for the diagnostics and repairing of the wire, this was about 25 years ago.

Love your vids. I'm no mechanic Tinker with cars a little bit. Just love to watch these videos. I want to thank you for taking your time to make them because that takes a lot of your time out of the day besides trying to diagnose the problem. Setting up the camera editing so on and so forth. I want to encourage you to keep on making these videos because they are very interesting and there are a lot of us who enjoy watching them and maybe don't respond with a like or a comment. I appreciate when I get likes and comments on my channel it lets me know that people are watching and care. Thanks again bro.

[@davidhenri2722]

Great video. Some people should not touch cars. Heavy truck mechanic myself but can make my way around a car. Not long ago my brother inlaws truck would not start. He diagnosed some how to the aftermarket theft system on his own terms. After countless phone calls I told him I'm not talking about it unless he tows it to my place and leave it with me and I will call him when its running. Removed the anti theft system and put the truck back to factory like he requested and made no difference. Truck cranks, runs for 1 second and dies. Fuel presure good, spark good. No anti theft light (passlock system). Grabbed wiring diagram and checked anti theft, ecm, antilock, airbag modules.....codes in everything and could not communicate with ecm. Test all wireing and checks out good, focussed on can-bus wiring for no comuniction between datalink and ecm. Deemed ECM faulty. Got used ecm from junk yard for $45. Program pass lock. Truck started. Check other modules. All codes are now gone. Run engine and engine misfire detected when going through a crank re-learn. Replaced plugs, wires, cap and rotor. Engine ran great. Crank relearn completed. Engine idle still rough when warm however but smooth at high RPM's. Perform cylinder cut out, #6 cylinder deemed not firing at idle causing rough idle. Check compression and perfect. Pull throttle body and dropped camera in intake. Injector spider leaking at the rear. Replace injector spider assembly. Truck runs perfect. In hind site. With that fuel leak. It explained why the truck would run for a second or longer depending how many times you cycle the key. End of the day, he has the best running 4.3l 1998 chevy truck that i have persoaly ever heard. He faught with that thing for a month. Had it running in 5 hours including the removal of the anti theft system that he swore was the problem and that he wanted removed. I knew it was not the problem but wanted to prove the point to him so......

In the 90’s GM and many other car makers started to prevent over revving their engines in park or neutral by cutting off the fuel usually above 3500 rpm’s. This almost sounds like that rather than a clogged catalytic converter. Although I don’t remember them sounding like a bogged down engine, but rather a sharp rpm cut off. I’m sure he would have taken a test drive to verify, but like he said, the customer only wanted him to get it running. Great video 👍🏼

[@jackpatteeuw9244]

WOW ! First time I have seen your parking lot EMPTY ! I have seen folks jam connectors in the wrong module as early as 1980. If you stuck a feedback carburetor control module in a central fuel injected Lincoln Town Car, all the pins would line up, the computer would start and within about 30 seconds you had fuel bubbling out of the intake manifold. Hit the start and the engine hydro locked ! How about adding a quick follow up like how much the cat would cost installed and did you get the job.

[@sparkzbarca]

I'm guessing he wouldn't do it in which case he wouldn't know the price. Based on having to get my cat replaced, normally you actually go to a muffler shop. I think largely because while i'm sure many mechanics have at least a passing knowledge of welding, when your doing it on someone else's stuff and your getting paid a good amount per hour to do it. You basically better be exceptionally competent at what you are doing. You can't risk leaving an exhaust leak or a weld that didn't use enough gas to block oxygen and now you have a weak oxidized weld or didn't use the right filler rod for those temps etc etc etc. Good enough welding is well good enough, but gas flow rates for example depend on is it an inside or outside corner, welding from the outside like you would do for a muffler requires more gas flow because it disperses faster than one that settles in an inside corner, likewise a weld torch directed up to weld instead of down again, requires more gas to keep the weld oxygen free, a circle requires that you adjust your position several times, which requires that you stop and restart a weld, something that can be a bit of a trick, reflowing a weld multiple times can be easy to screw up for novice welders. This doesn't consider things like variable diameter thickness on different pipes, proper fill rod, ensuring you get a super clean surface to work on when what your trying to clean is likely covered in carbon deposits, I wouldn't want that kind of thing done by a shade tree mechanic who does welding a few times a year. I wouldn't want to just wing it with something like that on something that wasn't mine. Not when someone is going to pay 600-1200 bucks for the repair.

[@Hendogg28]

Don Ziolkowski.. Exhaust work isn't as hard as you are describing. It is actually pretty easy to do. If you have a decent wire welder. I can weld and do every now and again in my shop. The only reason I use a guy in anther town is cause I don't have a 8,000 dollar pipe bender/sizer that make the job go by in minutes compared to hrs.. He can get me in about any day of the week and can do the job in use lee less than 30 mins. And time is money in this kind of work.. They don't grind off the rusty pipe or carbon, he mite take a hammer and smack the pipe a few times to get rid of any loss stuff if that. He just sizes it slides it over and throws a bead of weld on it.. Sometimes he will just put it inside the pipe as opposed to over the outside.. I've used him for meany meany meany yrs with out any problems what so ever.. He uses the same wire welder and same gas for all of his welding. And he uses carbon dioxide for the gas cause it is much cheaper to buy and use.. Same as what they use in Fountain drinks.. Your just making it sound much harder than it really is...

[@warjester4151]

That’s cool that another mechanic sent the car to you. My daughter bought an 02 Monte Carlo that over heated. The fans didn’t work so a “mechanic” spliced the fan wires and ran a wire from that to the inside fuse box and tuck the wire in the radio fuse. Nearly set the car on fire, melted the fuse in the box. I looked at the cooling fan fuse and it was blow. Replaced it and removed their wire. Car hasn’t over heated since. Lol

Knew it was fuse right away, sure you did as well since that was the first thing you checked. But how you took the extra effort to investigate the problem further and make your diagnosis is what makes you awesome man! You are worth your weight in gold.
