    No codes, power loss

    Here is the last DropBox instructions I had put together, it has been a while, so I have no idea if DropBox has changed the way the account set up process works. But I have had no feedback or complaints lately. You might as well do this for many purposed because DropBox is just a cloud based...

    No codes, power loss

    BTW, what phone/tablet platform are you going to be dealing with? Android or iProducts? Keep in mind you may be able to get the wife to use the phone to video things so you can see what is going on and/or use a video chat program. So checking for broken exhaust manifold bolts can be done...

    No codes, power loss

    So if the knock sensors are picking up any kind of knock or noise, it can retard the timing and cause a loss of power and sometimes this may feel like a partial misfire. BUT, again, the timing could be easily monitored and graphed on most decent scan tools. A 3 degree reduction in timing can be...

    No codes, power loss

    A decent mechanic should be able to see this while viewing Live/Realtime data. But my $4 Android App will also Log all the data as well. I review Log files all the time on other forums.

    No codes, power loss

    Sorry the fuel pump did not resolve the problem. I hope the fuel pump replacement was not $900. If it is, I would like to understand the cost breakdown. Seems high to me, but I also do not know the city and state were this work is being done. So if the systems are still the same, assuming there...

    No codes, power loss

    Here is my take, with this kind of mileage, I would replace the fuel pump and filter out of a Preventive Maintenance measure anyway. Unfortunately you are not in town, but not sure you would do the work anyway. Fuel pumps do not last forever and when they hard fail, you are left stranded. Not...

    Diagnostic tool

    OBDII is still the standard for SEE/CEL lights and drivability issues. Smart phone/tablet Apps are still relavent.

    Diagnostic tool

    Start with a smart phone OBDII App and interface, they are under $30. Android platform look at Torque Pro or TouchScan for Android and get an ELM327 Bluetooth interface from Amazon. iProduct platform loot at OBDFUsion and get an ELM327 WiFi interface from Amazon. Windows phone platform...

    2002 Surburban will not start.

    Fuel level has little to no effect on fuel pump life, this is a total urban myth. Most electric fuel pumps are DC brush motors and have bushings. Think of it like a starter motor. The brushes, commutator and bushings wear out over time. Most pumps last about 5000 hours. Its not a mileage...

    Leak, passenger front side

    Cannot tell from your pictures, however, every car I have ever worked on has the inner vapor barrier sealed to the actual door with some sort of sealer, sometimes single use sealer. Here is what you must understand, water will get past the gaskets and into the door, this is "normal". The...

    Leak, passenger front side

    If you know 100% for sure that the water is coming in at the door, you may have a problem with the inner door vapor barrier? If the door has ever had a window regulator replaced, which I understand is a somewhat common problem on these vehicles then there is a very good likely hood that the...

    Leak, passenger front side

    I have been researching this water leak problem on my 2005 GMC Denali that I purchased new. Problem started sometime this Summer and at first I thought the problem was just the smelly AC evaporator problems. After more research I figured out the carpet on the passenger side was getting wet...

    2005 Yukon Denali Fuel Pump and Filter Question

    Thanks for the responses. I have searched a bit and it was unclear with the 2005 and it may have had an in tank/non serviceable fuel filter. I will crawl up under the trunk in the next few days and see if I can find anything on the frame rail. I deal with a lot of German cars and they...

    2005 Yukon Denali Fuel Pump and Filter Question

    I have searched around a bit, maybe not well enough, but I have a few questions on the fuel pump and filter for a 2005 Yukon Denali. 1. Does the 2005 Yukon Denali have a serviceable fuel filter? If so, where is it located and what other years have the same configuration? 2. Fuel pump life...

    Heater on driver side while ac is on full blast

    Once the actuator was removed, I marked the center actuator part relative to the case, so when I took the actuator apart, I would realign the black gear so I would install the actuator back under the dash without issue. I then used a small screwdriver and carefully opened up the actuator...
