Cadillac DTS/ Buick Lucerne Fuse Box Repair, No Start/ No Fuel Pressure/ Stalling While Driving
Вставка
- Опубліковано 12 вер 2024
- Commonly on the North Star equipped cars from 2006 to 2011, the fuel pump will kill the fuse box and require a fuel pump and fuse box replacement. This video shows how to repair your fuse box without buying a new one.
Symptoms of this issue include stalling while driving, no start condition, and no fuel pressure.

Thank you, Travis. Thank you, Travis. I would say that 100 times.
I followed your instructions and I fixed my friend's DTS. The same problem, the fuel pump pin was heated up and oxidized. Luckily it was in a better shape than your fuse box, only a little bit heated up, but enough to not power the fuel pump.
I didn't have a male-to-male connector at hand so I decided to swap two connectors inside. The one that powers the coil of the fuel pump relay requires less current (only a few hundred mA) so I put the heated connector on its pin and I used the good one on the high current pin. Didn't test it yet, but I am sure it will work fine.
I really appreciate your video.
FYI I just went through this problem, on some other Internet videos and forums for the Buick Lucerne's they noted to a problem with the back seat bracket pushing on that corner of the fuse box causing arcing over time and there's apparently a new "shorter" fuel relay available and some people have shaved down their seat bracket. Anyway I filed down a section of a Bobby pin pretty good (any flat piece of metal would work) and shoved it in the burnt up hole and inserted the new relay and she's purring like a dream. Don't know how long this fix works for but good luck, this worked for me without having to take the fuse box apart.
How long did this work?
This worked for about 2 months when I tried it.
Thank you so much for the video. Instead of getting new female-female connectors, I found the one that was loose and soldered it. That allows it to take high current without causing it to heat up. Can also swap one out from a low current circuit.
I have a 2008 dts had a hard time finding the male to male connectors myself I was broke down so I used one of the Male 2 male connectors of 5amp fuse and put the burnt one back in its place just tighten it up a little bit with a pair of pliers started the car up and drove it all the way back home 300 MI the video is very helpful when drilling out the backside of the fuse box be sure to drill slow the blue 40 amp fuses are hard to pull out but they do come out LOL
I'm going to have to try this. My DTS is having this issue as we speak. replaced the fuel pump and relay but noticed the same hole was melted a little. Started a few times, moved it and it died again yesterday. Another melted relay. I have a new used box on order, but it would be nice if I could drive the car before that. You can by pass that hole by running a wire from the post to the corresponding relay leg, and wires running from each hole to the correct legs on the relay, and mount the relay outside the fuse box.
Update. Fuse box I bought was wrong, so being pissed off I did this. Relay is tight now, and the car fired right up and relay remained cool to the touch. I did not drive it though. I let it idle for a while. I have anxiety with driving the car now but I gotta do it. I also hacked that thing off the seat.
got the same issue on the fuel pump relay on my 97 k2500. This causes random shut offs while driving, going after it this weekend.
Hey there. Did the repair replacement connectors work? Or did U install new fuse box. Thanks.
This repair is a permanent repair.
@grandpasbuick so the repaired box was reinstalled?
@@fmarquez35 not this one, but I did a different one the same way, yes
I had hired a mechanic. I didn’t know the time had a drug problem and he went and tried to repair my fuse box but was using a solder iron. Is the reason I kept having problems perhaps because he was using soldering and not a new malemale connector?
How much would you charge me to change the same fuel pump relay connector. I have been going crazy I have an 08 DTS I think you brother know I have to trim down the right side of the seat. Blessings Mr Travis
hey is it possible you could email me a picture of the inner top half ....just wanna see if it could be dremeled around the 4 female input and some how exchange from top
Send a private message to my channel with your email and I'll send a pic over if I didn't throw it away already
It looks like you could use a cutting disc around just that one peg and slip out the old one and slip in a new one.
Dont you just have to seperate the fuse box from its base with the 4 tabs. Then when you do this you will see all the wires going to back of fuses. Dont worry they cant come out. Yet. Then with a 7mm socket you can access the "3 rivets" which in my case (2010 Lucerne) is actually 3 bolts. The nuts are on bottom side holding the wire termination plastic retainers. I hope this helps. I dont mean to say this guy is wrong because some years/models etc they very well may be large rivets. But the 10' Buick Lecerne had long bolts.

How exactly do you get the square rivits out to pull it apart?
Drill out the side that's not square, then pull the pieces apart. The square part can stay in its piece.
The heat from drilling the rivits melted the metal into the plastic!
That's what happens when you use a dull drill bit. That metal is pretty soft and should cut away pretty easily without heating up if you have a good drill bit.
How do you remove the connector block on the bottom?
Should pull off after loosening the screw in the center
@@grandpasbuick That's what I thought. No such luck. On any of the three. I thought that a bit strange.
where do u get the male to male connectors...🤷🏿♂️
The only place I would know to get them are at a junkyard, just tear apart a fuse box in the junkyard and take a couple out. That'll also give you practice taking one apart without breaking it.
I think i got the same problem, i need to change the fuel pump too?
Yes, the fuel pump is what kills the fuse box.
@@grandpasbuickit 100% faulty or may it be only clogged up or dirty?
@@hananelbitton5157 I suppose a significantly restricted fuel circuit could cause the same thing.
wouldn't it only burn up the fuse box if you jumped the relay? the circuit breaker should prevent that as well as the fuses. this has to be a short
@@coryc5545 No, it is a shitty design by GM. Very common problem. Bad fuel pump, or the stupid seat bracket putting pressure on the fuse box making the relay tweak. Replace fuel pump, cut some of the bracket off so it no longer makes contact with the fuse box. It is just poor engineering.
What if I change the relay
If changing the relay helps, there would be no reason for this extensive video... It won't help anything
Where do I find those connectors
From another car in the junkyard.
@@grandpasbuick can it be any other GM fuse box around the same year?
@@asid731 I would assume so but I have not actually checked.
