09 Yukon Full battery no crank

[joshuaryan]

Hey All, I thought I had this problem fixed a year ago when I bought a new AGM battery for my Yukon and my electrical issues had seemed to be gone, for a full year!

Now, this week, wife says when she goes out to start yukon, everything lights up but car only makes a single click noise when trying to turn ignition. After several attempts, the vehicle will start and is fine the rest of the day?

I can't reproduce it at will, it's completely random. Electrical is passing tests, so is starter, alternator and battery. (I keep a spare battery in second battery tray just in case but have not needed it thus far).

I have never replaced the battery cables which I hear is a frequent fix. I know many have had this issue all with different resolutions. If it sounds familiar to yours, let me know what you did to fix it, or if the battery cable fix did the trick, let me know. I think that's what i'm going to do next.

my tahoe did the same thing when the fuel pump was going out
itd start on the 2nd or third attempt and then never have any issues the rest of the day

I'll keep that in mind, right now it's just acting up again. Tried to start yesterday morning, no luck, tried again later and it cranked with no issue

actually im a moron scratch that you said it would just click when you tried to start
when my fuel pump was going to mine would actually turn over on the first couple of attempts and then on the 3rd or 4th try start up

That's the way this Esky is at the shop. It's an 07 and gotta mess with it to crank and start. But that's not a problem on it it's wrecked lol.. If I figure it out I'll let you know but I'm really just fixing the damage

a bad starter solenoid would cause the symptoms your expierencing

i havent tried it on a tahoe but what you can try if you know how
next time the key just clicks jump the solenoid and see if it starts if it does that usually means the solenoids bad

screwdriver maybe even a coat hanger a wire one obviously and the key has to be in the on position
