08-11 Buick Lucerne Fuel Pump Relay Cheap Fix
Does your car not start? Think your fuel pump is going out? Keep blowing fuel pump relays? Then keep reading.
Had this happening in my 08 Buick Lucerne. Basically the rear seat brackets on the left hand side stick out a bit too far and push on the side of the fuse box. This is a known issue and has had recalls; apparently GM has made a low profile relay to help with this but I haven't come across it yet, however once you get to the point of blowing relays I am doubtful it will help as the socket is too loose by then. But ultimately this pushing from the seat bracket on the side of the fuse box over time as people get in and out loosens or wears out the female/female spade style connector i...

Or use an external relay socket.
I did this fix and it is working, I am concerned that the aux port is always on even if the car is off. Does this mean the fuel pump will always be on also?
@@sorenstroud1761 yes the aux is constant 12v that goes to the constant 12v of the relay. The relay is basically like a switch. When you key the car on a signal wire tells the relay to switch to the 12v constant to power the fuel pump. So to answer your question. No if done properly the relay should function as normal and switch off when the key is off.

what size fuse is inside the inline fuse? did u find out if u were over fusing?
wonder if this is still working after 5 months?
@@simmy5883 Yes, still working well. Have not had any issues after the fix.
Thank you for this. My younger brother is having this exact issue with his Buick Lucerne, and we simply cannot afford several hundred dollars right now. He's owned this car for about 6 months and we've already sunk several hundred dollars in repairs into it, and now this. This would be a huge relief if this is the problem. I'm not sure that he knows to look for another fuse box (under back seat) so great info. Thanks again.
@@Doxymeister hopefully that's the issue, relatively easy / cheap fix if that's the case.
Hello I’m glad I’m came across this video I have the same problem but pin 87 is burned up will this still work ?
The commenter just above you used the horn relay pin and it's working pretty good. Good luck, we're having the same issue with my brother's Buick.
Thank you
So I did all of this and the relay is still getting hot, do you think I’m too far gone already? I can’t really afford the fuse box right bow
@@iamharley4325 the relay will still get warm to the touch but shouldn't be scolding hot. Wonder if you have a bad ground or bad connection from relay to fuel pump. Are you still viewing relays with the fix?
I just did this, the relay is still hot to the touch, but not so hot that I pull my hand away... I put a heat gun to it and it was about 130°
I wish I had a fuel pump problem I have an 07 Buick Lucerne an I have no idea what's going on with it won't start won't crank all I get is a click I've replaced the battery and starter nothing has changed I don't know what's going on with it
Do you have a lock symbol illuminated on your dash when key in?
.
This is crazy I was going insane wondering why i was blowing relays my local shop scammed me out of 2k replacing the box and relay
Sorry to hear that. It's not a commonly known fix. I had to do a ton of digging. The more views and likes the more likely people will find the fix. Appreciate the feed back. Make sure you cut the seat bracket back so it doesn't happen again down the road.
@@SupaJunnt will do man thank you!
If I don’t have that area to put that spade connection can I run it to my battery?
Yes. That spade connection is 12v constant, same as your battery post.
@@SupaJunnt what size gauge wire did u use this issue is a headache and I could use that 600 on new box for my kids instead thanks for any info
@@marcusrodriguez4272 Not sure on exact gauge. I would imagine 16-18 gauge stranded. Maybe even 20ga. But most likely 18 gauge. "Think speaker wire thickness." It doesn't need to be very thick, in fact that would probably not be beneficial as the relay still needs to plug in. I would go with 18/16 gauge.
Wanted to think you this actually work I'm driving right now texting this and my relay haven't blown 👍🏼
I don't understand how you grounded it
The relay has a dedicated ground, I forget which pin it is but there is already a ground where the relay plugs in, the problem is a lack of positive voltage typically.
I used 14 gauge home wiring. 2 feet wire, strip ends 3/4 inch. Hammer stripped ends flat. Wrap wire around pencil to coil wire. Remove relay, push flattened copper into hot slot of fuse box. Insert relay. Stretch other end of wire to horn relay hot slot. Then push relay back in. Working great on mine. Barely gets warm in 30celcius day.
No reason that wouldn't work. Like the idea of pounding out the wire and making a spade insert. Probably way beefier than it needs to be but no reason that wouldn't work. We don't use the horn much so that shouldn't cause a fuse to pop unless you hammer on it in traffic possibly (the horn) and even then I am doubtful you will ever have issues. Well played. I like the ingenuity.
Will that cause the fuel pump to go out?
Yes, the relay controls power to the fuel pump; a relay is basically a switch that turns the fuel pump on. So if the relay is not working you will get no power to the fuel pump.
The only thing I did different from what you did is, I bent the #30 prong on the relay, into a U-shape pointing up and then put a female, spade connector on the end fuse wire. Now instead of shoving the wire down in the hole you just push the female spade connector over the pin, it’s a tight fit between the little 10 amp fuse that’s right next to it but it’ll go.
Love it, that works too. I like it. Still working well I hope?
Did this it worked for about 3 months and had to replace the relay.
It may have been bc my fuse disconnected from the 12volt constant not sure tho. Put a new one in a drive around and it did not get overheated this time around.
@@jackvollo7541 Make sure you cut the bracket back s it does not agitate / loosen the relay by pushing on the fuse block lid. Yes a loose fuse / wire would definitely cause it to get hot or not start at all. Depending on how damaged the socket is on pin 30 for the relay you could try a larger wire size to ensure snug fitment / proper connection. Going on 4 months with my fix and still works great; no issues.
Where did you get the inline fuse and yellow connector from? Like autozone or something? Can you provide both links? That a be awesome thank you
I got the inline fuse off amazon and I had the spade terminal in a terminal kit could probably find both at Autozone.
Would you suggest cutting the bracket back or adding the wire or both to make sure I don’t have this problem in the future?
I would do both and it should future proof it.
Thanks for the tips. I installed a new relay but I still needed the jumper wire also. Is it because the black fuse box is bad?
Yes, the connection in the box is loose where the relay plugs in (pin #30) and not getting correct voltage. Unfortunately jumper is the only reliable fix without replacing the entire box. Glad it helped!
Will changing the 20 amp relay fuse to a 30 amp fuse help the problem
No. The issue is with the connection to the relay and not the connection to its parent fuse. Increasing fuse size would make no difference with the relay connection.
What is the yellow piece that you put on the end of the fuse line to connect it
That is a 'spade terminal connector' they come in various sizes. The color i believe correlates to wire size / Spade terminal size. Put it over the exposed wire and crimp it on. Or if you don't have crimp tools a pair of pliers will work.
Replaced the block and got a shorter relay about 7-8 months ago. Literally JUST had to have this done on my 2009 Lucerne 🤦🏻♂️ Got my car back a few hours ago😭😭😭
Sorry.... well it's fixed right... Might want to still cut that bracket back.
This is exactly what is happening with my car and thank you thank you thank you because absolutely nobody could figure this out for me and my car has been out of commission now for months and it's a fairly new car. I'm going to get the parts to do this now but I have a 2009 Buick Lucerne CXL will this same fix work on my year and model as yours, I hope?
Yes, should work for any lucern from 06-2011. Glad I could help. Post an update once done.
The J Case #49 seems to be the location of one end of the inline fuse, since that spot is designated for a 40 amp BLOWER, do you know which blower it powers? By the way this does work, I'm driving right now as a result of this technique, thank you.
J-Case #49 is designated as not used on 08-11 Buick Lucerne. www.autogenius.info/buick-lucerne-2008-2011-fuse-box-diagram/ #48 is designated as a blower. Not sure which blower. If I had to take a guess I would imagine the blower would be for your blower motor located under the dash that controls the output of heat / AC through your vents. Just my guess.
Definite life saver, thank you, going to get the parts later today.
Glad it helped. :)
@SupaJunnt thanks for tip. What is the opposite end of wire connected to? Is that a yellow cap for the exposed wire? Or is it connected to metal of the fusebox...I see the 12awg 20v wire under the fuel relay, but, on the opposite end I see the yellow on the other end, what is the other wire connected to? I have a 2009 Lucerne I have used a paperclip to get it home but I got the 12awg wire with fuses, 20V and 30V. Trying to mimic your repair. Thanks for any assistance.
