Thank you for the video. I'm buying a 2010 Lucerne this week. I'm going to check the fuse box. The rear seat bracket on that side of the car is too long and puts pressure on the fuse box. It needs to be trimmed as well
I had a 11 Buick lucerne cxl and found that the seat bracket that goes into the hole right next to the fuel pump fuse in the box. Is to long and presses into that corner of the fuse box creating fuse problems. So before you have problems (and you probably are if you're watching this) or after replacing fuse box. Trim the metal piece on the seat bracket so it won't rub and press against box.
I’m finding mine acting up in this way. It’s going tmw to get the fuse box replaced, fuel pump was changed a week ago. I didn’t realize the fuse box was burnt up til after I replaced the fuel pump. I’m glad I found out bout seat bracket before having to replace all of this shit again.
I had all kinds of problems with my 2009 Buick Lucerne. The solution was the seat bracket is hit the top of the fuse panel and causing it to shake around in the relay and wear out the contact and then burn up the panel. there’s videos out there about how to trim the seat bracket. A lot of times if you look on the cover of the fuse box, you’ll see were the seat brackets hitting.
If anyone is wondering why their relay get super hot and car won`t start.The correct fuel relay has the numbers 8385 written on the top.When placed in the fuse box those numbers should be towards the drivers door.Not all 4 pin relays are the same even though they fit and work.Some will not dissapate the heat properly.When you put the wrong relay into your fuse box and it heats up it causes the prong connectors inside the fuse box to spread and not make proper contact,which causes more heat and more problems.I actually went to an auto parts store and bought a fuel pump relay and they gave me an aftermarket one that was not the right one for the car and caused it to overheat.I replaced it with an 8385 and does not heat up at all anymore.Just thought people should know bcause i see a lot of people guessing at the issue.
I have recent experience with this and I am still dealing with a non-starting car. I replaced the relay, it started and cranked, and ran for a few days. Now it will not crank, but will start (turnover).
What would make buick 2008 lacerne all sudden sound like it missing or coil pack going bad but will cut off while driving ,spray brake cleaner on air filter will start up run fir bit but missing bad help
Apparently if you replace the fuel filter every 20-30,000 miles, it'll stop the fuel pump from dying. I just got an '09 Lucerne yesterday, and I'm gonna replace that filter ASAP.
Yeah the dealers, or find a used one from the junkyard.. I replaced the fuse box twice.. and it kept burning out.. the pumps burn out and burn the relay fuse out.. it's a design flaw in the fuel pump and fuse box.. it will keep happening. No matter how many times you fix it.. it's just a cheap part.

@@sambrown6426 look under the back seat cushion.. your fuel pump relay will start bruning out.. make sure you put an external relay with a switch so it doesnt over heat and cut the back seat bracket as it hits the relay box.... otherwise you will have to buy a whole new box.
How did this save you? I have same problem but this didn’t really offer a solution Did it? Yeah you can get a new box and/ pump but sounds like they will just go bad again. We’ve replaced both already and having same issue pretty much immediately.
Has anyone researched this 'chicken egg scenario' ? Tested fuel pumps before or as 'the' issue is arising, as well as monitoring the fuse block and relay itself? The big question in other words while there are tons of videos on this issue, no one seems to know which is causing which, a failing pump could cause the heat build up in the fuse box and failing fuse and relays can cause the pump to fail, circling back to 'chick / egg' lol ...
Your comment is 5 months old now but hopefully you will see this and perhaps it will help. A bad fuel pump should not cause the heating problem, why? Because the fuse would prevent that if the circuit was working as designed. However when you get a poor connection it is resistive and current flowing through a resistance makes heat, it also causes a voltage drop so the fuel pump is now running on a voltage lower than it would otherwise be. Excessive current will make heat but the pump can't draw that much current without blowing the fuse. So the poor connection came first. I doubt this would hurt the pump, this only makes it run on reduced voltage. A failing pump won't cause heat build up in the fuse block unless there is already a bad connection in the fuse block. Hope that makes sense.
@@chuckreed2677 I'm going with this solution since I still drive my car on short distances, feel the relay after I reach my destination, and it gets hot. The fuel pump seems to be fine as the car still runs smooth and I hear it priming when I start the car. These fuse boxes are ridiculously priced from the "STEALership and they are nowhere else to be found new.
@@chuckreed2677how does the connection become loose? From where the box sits? And if you hit a bump it just becomes loose on its own? Or could the box just be a manufacturing/design flaw with wiring shorting out in the fuse box? Could condensation cause the relay to become corroded or loose?
@@nathanburch5462 An excellent question, wish I had a definitive answer for you. If this happens to lots of cars at the same connection point I'd say it's likely a design or manufacturing flaw. Perhaps it not a tight connection when new and over time it gets worse from vibration. Humidity can affect the connection but if it's under the back seat I'm not sure why it would experience more humidity than anything else. Fumes off of the battery might affect it as well but I think there would be visible evidence of corrosion. I'm really reaching here. My best guess is that the connection starts out less than ideal when new with some small resistance so it heats up a little, over time the heating begins to add to the poor connection until eventually it causes a failure. That's probably not much help but I took a stab at it.

Thank you so much it’s exactly what was going on with my vehicle
can u talk to me asap im looking for a way to start it and keep it running even after I do everything and if there's a recall?
Im having issue with mine randomly shutting off while driving, looking into buying fuse box and fuel pump.
Where can someone order a new fuse box assembly?
What would make buick 2008 lacerne all sudden sound like it missing or coil pack going bad but will cut off while driving ,spray brake cleaner on air filter will start up run fir bit but missing bad help
Did you resolve this?
Many thanks!!!
What if you replace both of them and it’s still doing the same thing?
Did you figure out the problem?
What was it?

Yo man where you get these fuse boxes? I can only find used online
Is this something I have to get from the dealer?

@@nathanburch5462 I was already gonna cut the seat bracket, but the external relay is a good idea too.
Can I try by just changing the relay and the 15 amp fuse ? Or do I need to buy a new box ?
My buick is having that same problem fuel pump not getting power
You saved my azz. Thx
Why my interior lights won't turn off. What is My Problem?
you saved me !!! thank you soooo much!!

The fuel pump is integrated into the fuel pump. Change the fuel pump is all you have to do.

No volume?
