2014 GMC Yukon XL having hard time trying to get it to start

On my 2014 GMC Yukon XL sometimes wont start with remote and recently car will not start after cycling key a few times as well as hitting unlock key it works. I pulled negative on battery and let it sit for 30 minutes. Worked great for a day and then the next morning back to being hard to get to start. When it does crank it starts great. I think the problem is in the security or the key. Am i far off from being right and is there a way to reset it? Also when driving down road the A/C controls are not working. The radio will turn on and off. The security, ABS, tire pressure , and air bag displays on the dash. The computer will display check tires and service air bags flashing. The speedo and tach also go up and down. Acting like security system thinks its being stole.

SOURCE: 1997 Blazer dash displays ABS light, Air Bag...sometimes battery light.

I think your BCM which is the body control module has failed, have a self test run on it to see if it will give any codes, if it won't test then it is the problem.

2002 GMC Yukon XL 5.3 Cold start


What happens if you bring power directly to the starter solenoid? Will it crank then? You need to try to isolate the problem. If it will crank with direct power, the starter is NOT the issue. Let us know what you find.

My 2004 yukon xl wont start


You need spark at the right time, fuel pressure at the injectors, and normal compression.
Have the spark plugs been changed in the past couple of years ?
Have you checked the fuel pressure to see if it is enough ?
Have you sprayed carb cleaner into the throttle body to try to make the engine try to start ?
Does it sound like it has normal compression when cranking ?

Remote key entry dont work 2007 gmc yukon il


This is a tough one without testing but i can say that 90% of the time its due to bad remotes. first make sure the battery in the remote is good, if you have another remote try that one and also make sure it has a good battery. i have seen spare remotes go bad also. the best thing is that if both remotes dont work then buy a new remote and try that.

Since I purchased my 2000 GMC Yukon XL 1500 we have had a water leak that soaks the drivers side floor and passenger floor behind the drivers seat. I took it to my GMC dealer and they had it two days and...


You may be right about the sun roof. It should have 4 tubes to drain water that comes in around the glass. Sometimes the tubes fall off letting the water come into the cabin. The horn may be the part in the wheel. Apply it at different angles and it might start working. Sometimes they get rusty. I think your cabin filter would be under the hood near the firewall on the passenger side with a plastic cover.

2006 GMC Yukon Denali XL Rear Hatch & Glass locks not working


Could be the latch mechanism for the door is sticking. You could try using some white grease on the latch and the contact where the latch hooks to. You can purchase the grease from most auto parts stores. You will not need to use alot. Just apply a small amount to the mechanisim and then work it in using the manual handle. Then open and close the door several times to feel the "action". Then apply a little more and repeat. This should loosen the latch and get it working again. Also make sure that none of the tension springs have come loose on the latch. And check the seal around the door and make sure it is not pinched and has a proper fit.

My GMC yukon XL 2001 engine runs after 4 times of cranking.


Try turning key to on only, not start, 2 or 3 times first then try to start. If it starts good first try, then I'd change my fuel filter & then have fuel pressure tested if fuel filter didn't help. You may be looking at a new pump, but lets do filter & test fuel pressure first.

Gas tank wont' fill to specs


Based upon my experience, I would say it's a manufacturing defect. Something in the filler or the tank itself. I've seen cases where the dealer replaced the tank and related parts when this is happening.
