GMC Yukon QuestionsRefine by vehicle
We don't know what IT could be
I have changed the fuel pump, fuel filter, the fuel relay switch, which gets really hot for some reason, changed the EGR valve. I took it into a mechanic and they thought it was a vacuum leak, and they said they checked it all and thought they found one. They called me and said it hasn't stalled and think its fine. Went and picked it up and I wasn't even a block away and it stalled as I was driving, had to pull over(keep in mind still has power, pulled over put in park then started it back up and it started. Drove it home no issues, drove it the next day and same issues..... Tried troubleshooting it myself again, looked at the vacuum diagram and it showed they had the hoses switch for the one going to the fuel tank. So I switched them, drove it for two days and it was fine. Then today it was back to same issues but much worse, just be driving along and rpm drop to 0 then it stalls out and have to pull over, sometimes it will start right back up, but today it just wasn't happening.... Any idea's, thoughts, would be greatly helpful, just don't have the money to take it into a mechanic, pretty good with vehicles and have worked on a few, but this one has me so confused.....
My truck won't take gas. Replaced canister purge valve, solenoid under hood near intake & fuel cap, finally took to shop & they replaced fuel vapor canister & blew out all the lines. Still NOTHING after all of that.
The fuel tank pressure sensor above the gas tank has not been replaced as of yet.
Any input? What good is his "New state of the art diagnostic station"???
All doors are closed
Left work truck was fine stopped at store came out started it up and I lost powersteering and brakes are hard. Thats when i seen the return hose to the gear box was off. I replaced the power steering pump and the Hyrdro-Boost. Tried to bleed the hydro-boost but nothing comes from the return hose. I believe there is high pressure on both sides of gear box not allowing flow or there is blockage in line or a seal has failed somwhere. Please help.
I turn the selector to either 4 auto, 4 hi, or 4 lo. The indicator light will continually flash and I hear a click like the transfer case is shifting but will not actually engage. I have tried in park, in neutral, slowly rolling and even at moderate speed (30mph).
car is off. Is there some button or something that will turn them off when the car is not running? Of course the battery goes dead. Not sure of the year, can't find any papers or manual for this car in the glove department.
I had my oil changed and now the engine knocks?? The oil level is good, but the noise just started. Could it be the lifter? And what will happen to the engine if I drive like this?
Not getting proper signal from ckp.removed it and found engine oil on magnet.is normal
Trying to remove to replace got in fender bender and have leak needing to remove
I have a 2008 GMC YUKON SLT 4WD V8. I am having trouble with my fuel gauge. It will say I have 1/2 a tank then I can drive just a few miles and it sais empty. For example I had 123 miles left till empty last night. Today it sais 34 miles and the low fuel light is on. I don't know what to do. My husband and I just bought this car 8 months ago
I've tried everything. Checked the fuel pump, spark plugs, and carburetor. When I try to crank it it tries to turn over but can't quite make it. Any suggestion on what to try would be great. Thank you.
There is a unit under the front dash that is ticking when the air conditioner or air circulation is on. Sometimes it causes just heat to come out. What is that part so I can replace it or has it been recalled?
The lift gate door acuator no longer is working. My rear door does not lock. Has it been recalled? If not, how much is the part to replace?
When I put yukon in gear forward and reverse it makes noise !put in new transfer case and does it still! !only now have no park or reverse! !!!!what could be the problem? HELP
Replaced it and it still codes,, ground issue? something I missed? I assumed bank "B" is closest to the fire wall. Based on research,, but found no actual schematic,,,
If let of the gas at times an re acclerate it will catch a gear. But other then that when first taking off it wont change gears an rpms really high
When taking off its not shifting gears idles real high. There is times it will shift if you let off gas an accelerate gas. An sometimes speedometer goes out of wack
