On a 2002 buick century custom the horn relay under hood is what Amp fuse
Fuses and relays are two completely different things. Relays don't normally have a fuse built into them. Is this the horn fuse or the horn relay your referring to?
If it is the Relay, (a Small, square, black plastic block), take it to a good auto parts store and they be able to give you the correct one. The car will run normally without it.
If it is the fuse, ( a flat, coloured piece of Plastic with two metal 'ears'), they are usually marked with the amp rating as a number and the letter A. They are also usually colour coded having certain Amp ratings as certain colour. It is often a 15A fuse, possibly a blue one.

Where do the fuel pump wires run on a 1995 Buick Lesabre?
Hi. In a 1995 Buick LeSabre, the wiring for the fuel pump typically runs from the fuel pump relay, which is located in the front passenger door area, to the fuel pump itself, which is located inside the gas tank. The wiring is generally routed inside the vehicle, often underneath the carpeting and interior trim.
To access the wiring near the fuel pump, you will likely need to remove the rear seat. Here are the general steps to follow:
1. Remove the Rear Seat: Depending on your specific model and configuration, the rear seat may be secured with bolts or clips. Look for bolts at the bottom of the seat or clips under the front edge of the seat cushion. Remove any fasteners and lift the seat out.
2. Lift Carpeting and Trim: Once the seat is removed, carefully lift the carpeting and any surrounding trim pieces in the rear passenger area. You may need to detach plastic retainers or remove screws to do so. Take care not to damage the carpet or trim.
3. Locate the Wiring: Look for a wiring harness or conduit running along the floor or under the carpeting. This harness should lead toward the rear of the vehicle, closer to the fuel tank area. Trace the wiring until you find the connection point near the fuel pump.
4. Cut and Splice the Wiring: Once you've identified the wiring near the fuel pump, you can cut and splice the wiring as desired. Make sure to use appropriate connectors and ensure proper insulation to prevent any potential electrical issues.
It's important to exercise caution when working with electrical wiring. If you're not comfortable with this process, it's recommended to consult a professional mechanic or electrician who can assist you with the wiring replacement.
Additionally, please note that modifying the wiring of the fuel pump may have implications for your vehicle's warranty and safety. It's advisable to consult with an automotive expert or refer to your vehicle's documentation before proceeding with any modifications.

The camshaft sensor on this engine was located on the passenger side of the engine. You will need to remove the serpentine belt, and you can get to it by removing the inner fender or splash guard and get to it that way. I went down from the top. There are two sensors, one is a CRANKSHAFT sensor and other is a cam sensor. Make sure you know which is which. The crankshaft sensor is at the bottom of the engine, the camshaft is right by the water inlet. It is held in by 1 or 2 bolts. If your car is throwing the code for the camshaft sensor, just a heads up. I replaced the sensor and the sensor detects magnets installed on the camshaft. The engine kept throwing the code and came to find out one of the magnets had come off the end of the cam. I am telling you this just in case you go through the replacement and still end up with the code. the camshaft sensor is not too hard to replace, it's tight but it can be done. unbolt the old and bolt in the new. Make sure you disconnect battery before tackling this project. Hope that help some..

2006 Buick Lacrosse. How to test for a vacuum leak please?
Question edited for clarity.
Question moved to model category.
A 'Smoke Test' at a garage. They disconnect a hose and attach a smoke generator and under light pressure the smoke escapes where the leak is. The test takes about 2 hours.

2013 buick Encore Knock sensor location?
Greetings,
Based on the description from the Advanced AutoParts website, you should check the engine for the sensor. I would use a picture of the sensor to guide you in locating it around the engine area of your Buick. The item looks like a magnifying glass with no glass with bronze colored piece that lays within a black circle. You'll see what I'm talking about when you run it's name in a search engine image search.
Thank you.
