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!

    Curious why you didn't start with the horn?

  2. Avataaar/Circle Created with python_avatars Rodney Miller says:

    You are right about that!

  3. Avataaar/Circle Created with python_avatars Tim Williams says:

    Couldn’t have a disabling Alarm system on it

  4. Avataaar/Circle Created with python_avatars Tim Williams says:

    Could it be a starter relay

  5. Avataaar/Circle Created with python_avatars Tim Williams says:

    Could be an in-line fuse somewhere blown

  6. Avataaar/Circle Created with python_avatars Shawn Reagan says:

    Anti theft can kill the starting and sets of the horn

  7. Avataaar/Circle Created with python_avatars BR 549 says:

    That’s an odd place for GM to put the ECU

  8. Avataaar/Circle Created with python_avatars Ely Powell says:

    Man I had to shop around to find a mechanic like this for years,

  9. Avataaar/Circle Created with python_avatars vferrante says:

  10. Avataaar/Circle Created with python_avatars Sonia Rican says:

    Who else laughed when the Music came on ?…. 😂🤣😂🤣

  11. Avataaar/Circle Created with python_avatars angel perez says:

    I am so leaning towards a blown fuse

  12. Avataaar/Circle Created with python_avatars Don Carrigan says:

    One side of 3 hole fuse slot is hot at all times the other side is keyed power

  13. Avataaar/Circle Created with python_avatars Cidran100 says:

    Another awesome video.

  14. Avataaar/Circle Created with python_avatars Cidran100 says:

    Day of the weekend warriors is over when it comes to electronics. Kid should have just brung it you from the start.

  15. Avataaar/Circle Created with python_avatars Jim Vet says:

    good job boss.;

  16. Avataaar/Circle Created with python_avatars tresso says:

    Someone on Youtube replaced the CKP sensor thinking that it was causing the 4000 rpm limit and was disappointed when it didn't change anything.

  17. Avataaar/Circle Created with python_avatars former 11b says:

    “Owner said it’s got nothin’”
    turns key
    “Ohhh he meant NOTHIN’ nothin’…like not even nothin’”

  18. Avataaar/Circle Created with python_avatars Paul Gallagher says:

    It would be so easy for manufacturers to build a burned fuse indicator LED into each of the fuse positions. Cost pennies. Would be such a great time saver for everyone. It would eliminate a lot of trips to the shop.

  19. Avataaar/Circle Created with python_avatars Paul Gallagher says:

    I don't think I'd have the patience for that job. I used to repair all my own cars and was pretty good at it. I could do just about anything. But when you have to work on a car that has just about everything broken, its got to be very discouraging.

    I remember once a relative asked me to check the brakes on her Pinto. Jacked it up and was able to immediately diagnose the issue. I told her the front brakes were gone. She said she knows, they don't work. I said, no, they are gone. As in, there are no front brakes. She had worn them down to the point that the front discs became detached and the calipers both snapped off. I didn't know it was physically possible. Wish we had cell phone cameras back then.

  20. Avataaar/Circle Created with python_avatars Thomas Vlaskamp III says:

    Kid didn't need to know anything about that new computer. He just needed to compare the two and see a difference and be like "huh… that ain't right…"

  21. Avataaar/Circle Created with python_avatars TmOnlineMapper says:

    Ahhh the pain of not being allowed to fix stuff.

  22. Avataaar/Circle Created with python_avatars Michael Bachman says:

    Pressure test cat?
    Good video

  23. Avataaar/Circle Created with python_avatars Lon Chaney jr says:

    Lmao poop and laughter never heard that

  24. Avataaar/Circle Created with python_avatars Cummins Cummins says:

    Moving on !!

  25. Avataaar/Circle Created with python_avatars Mista 2 says:

    Cant believe , you took so long to check the fuses .

  26. Avataaar/Circle Created with python_avatars warren hymes says:

    I swapped a 3800 into my 1986 Pontiac Fiero. Best engines ever, IMO. As far as sending a car to you, I don't mind swapping in some new parts 1st just because. MAF sensors, IAC, TPS, IAT, coil packs, plug wires, etc. It eliminates that possibility and I have new parts. Sort of an electrical system tuneup.

  27. Avataaar/Circle Created with python_avatars Bill B. says:

    Knock out the guts of the cat and put a anti fouler on the o2 sensor. Lol

  28. Avataaar/Circle Created with python_avatars Joseph Rogers says:

    Why didn't you just be honest and tell him it's not a computer and replace starter he is going to get stranded

  29. Avataaar/Circle Created with python_avatars Mike Scoyne says:

    due we all call it sparkage lol

  30. Avataaar/Circle Created with python_avatars Arthur Everett says:

    New computers need to be programmed otherwise the car won’t run

  31. Avataaar/Circle Created with python_avatars Jacob Pie says:

    So did you charge them $2500 to replace those two fuses

  32. Avataaar/Circle Created with python_avatars Linsquip says:

    HEADPHONE USERS BEWARE 4min MARK LOUD BEEP

  33. Avataaar/Circle Created with python_avatars TJ Kaczynski says:

  35. Avataaar/Circle Created with python_avatars James Owens says:

    You would make a good doctor! Never listen to the patient!

  36. Avataaar/Circle Created with python_avatars Dennis Boyer says:

  37. Avataaar/Circle Created with python_avatars hearsejr says:

  45. Avataaar/Circle Created with python_avatars LTP Ma says:

    LOL !!! . Don’t tell this customer that you can do , and they can do it , they end up damage another PCM LOL !!!

  46. Avataaar/Circle Created with python_avatars Oroku_Sake says:

    I used to work on car electronics. As far as I remember the fuse slot being a "three prong fuse" for accessory specifically can mean that the 2 prong traditional fuse can be moved from one position to the other to make the cigarette lighter12v with or without ignition. IDK about Buick specifically but I know it exists out there.

  47. Avataaar/Circle Created with python_avatars Rolando Curro says:

    You Sir ! , Were born to be a mechanic. You're a natural !!. Really liked your reaction. When the radio just came on for no reason. And the tranny abruptly jumped into gear. Keep up with your great patience and the awesome analizing tech work. Kudos to South Main Auto Repair LLC
