In this video we have a look at a common problem that plagues these Buick Lucerne's. It got towed in as a "Crank, No Start" and we made a speedy diagnosis to find it had no fuel pressure. However, is it the pump? Is it a fuse or a relay? Or maybe the fuse box is melting out of it because the seat cushion is pushing on it!?! Stick around to find out! -Enjoy

    had a similar problem with a 65 vw bug. the 6 volt battery was under the rear seat. the seat springs contacted the battery posts when someone sat over it. caught the seat on fire. loved growing up in the 70s.

  5. Avataaar/Circle Created with python_avatars Larry Pallone says:

    Wonder how many of these Buicks have caught on fire ?.

  6. Avataaar/Circle Created with python_avatars Wraptor says:

    I had the same thing happen to my 2011 Lucerne. Helped solve the mystery. it wouldn't act up for my mechanic but stranded me twice. It would work until the relay got hot and would start again once the relay cooled off. Did find out that the fuse box p/n was changed to 84446205 which may have the shorter relay. Thank you Eric.

  7. Avataaar/Circle Created with python_avatars Hola! Ben Richter says:

    Sweet! Yeah had the same thing happen on my 08 Lucerne CXS and 08 Cadillac Dts. Both with Northstars both same problem within a few months of each other!! I just pulled out fuse box and pulled out pins on fuse block, and wired a new relay up outside of fuse box. Didnt even have to change the enitre box! Was a cheap fix but still running to this day! Lol

  8. Avataaar/Circle Created with python_avatars Michael Bennett says:

    So what your is the same thing i been saying for years they basicly are fucking stupid and chevys are garbage

    Cost of doorhandle replacement on a 2011 Buick Lucerne

  10. Avataaar/Circle Created with python_avatars Kevin Dimmett says:

    Thank you Eric just help me get my car back on the road. It left me stranded 30 miles away at the tire rack that I got at home swapped the fuse box and back on the road

  11. Avataaar/Circle Created with python_avatars 2l8and1 says:

    I have a 2011 Lucerne. No crank, no comms, no power to fuses 1, 28, and 37. Car doesn’t register it is in park. Sound like a bad Fuse block as well ??

  12. Avataaar/Circle Created with python_avatars JC Butler says:

    Great video… Really saved me… My fuse board wasn’t too badly scorched… So I was able to replace the module for about 12 bucks and it’s all good… My fuse box does have the mark on the side from the seat clamp… Thanks again

  13. Avataaar/Circle Created with python_avatars Terry Johnson says:

    My 06 won’t crank

  14. Avataaar/Circle Created with python_avatars iamhisman says:

    I'm so glad I waited to watch your video before working on my car. Your the Best!

  15. Avataaar/Circle Created with python_avatars Chris Campbell says:

    Dude you saved me a trip to the garage and an expensive diagnostic check

  16. Avataaar/Circle Created with python_avatars Louis Pushnik says:

    Loose connections equals high resistance which equals melted pin holders.

  17. Avataaar/Circle Created with python_avatars Michalle Crisco says:

    I am having trouble finding a new replacement for the Rear Underseat Fuse Block. Care to share where you got yours from Mexico??

  18. Avataaar/Circle Created with python_avatars Patrick Dwyer says:

    Thank you for a great video . perfect instructions

  19. Avataaar/Circle Created with python_avatars JUGGERNAUT 88 #GODFLOW says:

    Thanks. This video saved me;⚡

  20. Avataaar/Circle Created with python_avatars Linda Mason says:

    Why did you replace the entire box instead of just the low profile relay (as a first shot)?

  21. Avataaar/Circle Created with python_avatars Matthew Turgeon says:

    We had an 2011 come through our shop in Sherwood Park service Alberta thanks for the video! Love your channel Eric

  22. Avataaar/Circle Created with python_avatars Wayne's Guns & Stuff says:

    I love my 2008 Buick Lucerne but there's so many damn problems that you have to fix in the car and I only have 90,000 miles on it and it's the year 2021. The engine internally is good but every other little thing goes wrong with it it nickels and dimes you constantly or should I say dollars and hundreds of dollars cost you. And the transmission is funny on these cars too they start to kind of bang and shift hard after 70,000 miles. I mean what happens with the transmission, is you'll be trying to stop at a stop sign and then you kind of roll with it and go and instead of coming to the full stop and kicking in gear it just slams in the gear it's kind of like a rolling slamming gear transmission. I can't explain it but it sucks it feels like your transmission is going

  23. Avataaar/Circle Created with python_avatars Wayne's Guns & Stuff says:

    You can also cut off the little tabs of the metal bracket on the car seat with a Dremel tool cut off wheel easier to handle smaller to take the metal off instead of using that big cut off wheel just my two cents

  24. Avataaar/Circle Created with python_avatars Wayne's Guns & Stuff says:

    When you installed the new fuse box have you noticed that these fuse boxes get pretty warm and actually kind of hot? It just seems like there's been a few lessons that I've dealt with no matter if they're new fuse boxes or not they get really hot not extremely hot but pretty hot I was just wondering if you found that true also.

    Used this video to fix my son's 2011 Buick Lucerne. Fuel pump relay was fried. Bought a new relay. Still no start. Bought a new fuse box, installed it, and it started right up. I trimmed the seat bracket so hopfully it fixes the issue. I appreciate the video.

    That Astro pizza cutter looks amazing, my wife wants one for the kitchen!

  27. Avataaar/Circle Created with python_avatars Mark Ward says:

    A fuse box under a seat is a great reason to Never drive thru water.

  28. Avataaar/Circle Created with python_avatars William Duignan says:

    Thanks buddy!!!! I have an 08 Buick with the same problem….

  29. Avataaar/Circle Created with python_avatars Steveo66 says:

    you keep the old box, fuses, and relays???? Shouldn't the guy who paid for it get to keep it?

  30. Avataaar/Circle Created with python_avatars Colleen Drinnon says:

    How much should a repair like this cost?

  31. Avataaar/Circle Created with python_avatars Rick Rudd says:

    Thanks for the great video. I had this exact issue with 2010 Lucerne. I used to like my car but the fact that they did not recall this obvious safety issue is of great concern. Think about it: fuel pump shorts out at 70 MPH on the freeway….BANG no engine power. Also the backseat FIRE concern, my grandson sits in his car seat right n the fire / fume zone. Thanks alot GM /sarc/.

  32. Avataaar/Circle Created with python_avatars Bob Smith says:

    Toyota seems under-represented considering the numbers on the road.

  33. Avataaar/Circle Created with python_avatars Taurus The Barber says:

    Why not give the old part back to the customer?

  34. Avataaar/Circle Created with python_avatars v nappa says:

    2009 Buick Lucerne same issue no start, fuse box melted . Eric O repaired this the right way.
    My ex mechanic claimed the fuel pump failed also.( I 'm not buying this .)
    If a mechanic says the fuel pump failed make them prove it .Have them apply voltage to FP and see if it works. and keep the old parts .
    Also my ex mechanic did not check or know about the TSB 15-NA-051 and obviously did not make the repair . issue could have recurred .
    I wish Mr O should relocate near me . (eastern MA )

  35. Avataaar/Circle Created with python_avatars Joshua Solomon says:

    So question my 08 Buick Lucerne will start run for about 10 minutes then die could this be the problem currently waiting for someone to get off work to haul it home over hr half away or I'd be able to look but it drove perfectly the whole way there and died as soon as I hit the driveway thank God

  36. Avataaar/Circle Created with python_avatars glenniz1 says:

    What was the issue with the fuse boxes? DTS Cadillac vs Buick Lucerne?

  37. Avataaar/Circle Created with python_avatars joe wiese says:

    thank you for the video

  38. Avataaar/Circle Created with python_avatars IED David Foster says:

    It says shut the door because you know someone at the dealership backed it out of the bay and ripped the customers door off. Rules and notes are always because someone messed up. Lol

  39. Avataaar/Circle Created with python_avatars bwd1963 says:

    Ok i replaced my fuse box and has low profile fuse in it 😃 now , i take out fuses and reinstall them and it starts again . But next day it does not start? Soooo shall i replace pump as well? And yes i ground off seat clamp down ears.

    Those are Navy directions. Last step: "Close the door."

  41. Avataaar/Circle Created with python_avatars BM Eddy says:

    Dude, this is the most thorough video that i have found on this same issue that i am having! I will relace the entire box, just for a confidence factor! Thank you for sharing your knowledge and expertise! I wish you were my mechanic! Thanks again! Very nice work!

  42. Avataaar/Circle Created with python_avatars bwd1963 says:

    Great video my relay was blackened and melted somewhat and that prong seemed to have been made longer than the other three prongs . No one hardly sits back there ,but had a large box not real heavy but maybe enough to bounce around enough to cause my issue . Either way new relay and car started right back up.😁 But, do I really need a new fuse box ? I can easily grind off seat clamp .
