under the hood right in front of battery is a fuse box

your fuel pump is in the gas tank unfortunately

hi from uk this fault most likely the bulb has blown in high level brake lamp /3rd lamp as you say as you mention this car is 08 reg check the warranty period as it may/should be dealers repair ?for no charge ps if you or other drivers have a habit of sitting in standing traffic with foot brake on instead of use of handbrake ? this is prime cause of brake light bulbs o/heating and blowing element in bulb due to the actual b/light element is high wattage so burns brighter observe how many cars have one or more b/lights not working as you drive ? also bear in mind this is an offence and m o t failure as these light are obligatory (must have working ) and you can face a penalty if stopped by police

near the throttle body there is an adjusting screw(flat head) for air fuel mixture, it's on a deep cavity sometimes with a cover, adjust counterclockwise will increase the idle.

The pulsing only happens when the vehicle detects slippage (say on gravel, dirt, snow/ice) under normal driving braking you will not have any pulsating. Also if you have had $1300 in brake work the pulsating could have been warped rotors as well. I have seen the ABS light stick on for other reasons, faulty speed sensor or bad sensor and even light just sticking. Try putting it on some loose ground an braking hard so the truck slides a bit and see if the pulsating comes back its working fine, if not you still have an issue (could be your pump as well)

If the light is continuing to flash the 4X4 is not engaged, most likely the motor that engages it on the transfer case is either stuck or defective.

Sounds like the evap valve. Fairly easy, although potentially time-consuming, repair. The entire evap vale assembly should cost under $200. The assembly is right in front of the fuel tank under the truck.

it's an 08 model. if this happens to alot of people they will do a recall. i would call your dealer and let them know what happend so it can be fixed. from the sounds of it it is a workmanship problem and should be covered by the manufactor and should be replaced free.

ok before any thing you are not providing the year or engine size for your car, don't be worry i will try to help but you are not the only one not providing this very important information in order to get you the closes answer posible,
the first thing i will recomend you is to contact the dealer and ask for a list of recalls for this gmc, recalls are coming problems that dealers have to repair for free see if you gmc falls into this recalls and have it repair other than that the only thing i will sugest is to pull codes with an scan tool thats only if your check engine light come on, and see if the coolant sensor is bad and have it replace

Good place to get a vacuum gauge hooked up and identify problems using that tool. Without the gauge, check your exhaust and see how much if passing through the converter. You can do this by testing the temperature of the exhaust before and after the converter making sure the converter/exhaust isn't restricted. As the vehicle warms up a bad converter can cause the symptoms you are describing.

P1860 = TCC PWM Solenoid Circuit Electrical P0740 = Torque Converter Clutch Circuit/Open and P0785 = Shift Timing Solenoid "A" Maybe spurious codes, I can't tell.

Welcome. Two O2 sensors. One in the exhaust manifold and another after the cat. Feb 9, 2010

How Many O2 Sensors Are on This Vehicle?

The fuel filter for the 2009 Acadia is built into the fuel pump. To replace it, the pump will have to be replaced.

The C0292 code in your 2004 GMC Yukon Denali XL indicates a communication issue between the Powertrain Control Module (PCM) and the Electronic Brake Control Module (EBCM). Here are some steps to diagnose and potentially fix the problem: Check Ground Connections: Inspect the ground connections related to the PCM and EBCM. Follow the ECM ground and ABS module ground. Check the ground on the firewall (driver's side) and the frame rail under the driver's seat. Also, verify the engine ground on the driver's side. Inspect Wiring and Connectors: Visually examine the wiring harness and connectors associated with the EBCM. Look for any signs of damage, such as broken wires or corroded pins. Ensure that the connector pins are not bent or pushed out. Pay attention to any loose or poor electrical connections. Consider the Tune: If you've recently modified the vehicle's tuning, consider reverting to a different tune. Sometimes, a specific tune can cause communication issues. If you suspect the tune, contact the tuner for further guidance1. Professional Diagnosis: If the above steps don't resolve the issue, it's advisable to seek professional help. A qualified mechanic can perform a thorough diagnosis using specialized tools. Keep in mind that diagnostic costs typically range from $75 to $150 per hour.

It is not legal to 'adjust' speedometers. Fit the correct sized rims and tyres and the speedometer reading will be correct or use a satnav for real time speed.

The BCM is located on the lower left side of the dashboard just below the steering column

Fuel injectors are typically driven directly by power transistors in the engine computer. Relays are just not fast enough to provide the fine timing control needed. There might be an individual fuse for each injector soldered to the computer board, but I haven't ever looked at one for your model, and I've never seen injectors individually fused. Before chasing that, verify that the electrical resistance of the injector coil is the same as the other injectors. The typical resistance is between 100 and 1000 Ohms. If the coil resistance differs by more than 10%, replace the injector coil (it may be easier to remove the coil from a new injector and switch it with the old one than to pull the entire injector out and replace it, if not, change the injector). Shorts in the coil that lower the resistance are sometimes a problem. Also check the injector cable for continuity. An easy way is with an ohmmeter that can read at least 20 Megohms. First, check the resistance between the terminals on a good cable. You should read a very high resistance - this is the leakage through the transistor and any protective components, and is some number between 5 and 20 megohms. The exact number doesn't matter, as long as you see something and it is not a short circuit (less than 1 Ohm). This verifies that the test will work (if it reads over-range, either your probe tips can't reach the contacts in the connector, or the test is otherwise not valid). Next, repeat on injector 1. If it reads open circuit (over-range), check the injector cable (note: an open fuse will give the same result as a broken wire).

Backfiring can be caused by leaking valves, (compression leak test will show this), an air leak in the inlet manifold, incorrect timing. incorrect mixture or an air leak in the exhaust manifold. Very undesirable as it can lead to engine damage.
