I was wiring in my stereo. i didnt unhook anything yet and just ran the power wire through the black grommet of the firewall. i tried to start the truck but it doesnt start. The battery guage works and no others ones work on the cluster and the radio works but the drive/reverse/odometer doesnt light up. What can we do? Which fuses to check? We're running out of daylight to work in. I checked the wires in the big grommet and they seem to be all intact. Hope that makes sense I'm in a rush.

 

Oh and its an 01 Gmc sierra 5.3L

If your truck is like mine (99 suburban) then you will have a fuse bank on the side of the drivers dash between the door and the dash behind a little triangle shaped cover. You will also have a fuse bank under the hood on the drivers side towards the back by the ecm. Check them both and pull all fuses one by one. It sould not take any longer than 15 minutes. You just might find your culprit there.

      Still looks like a rivet to me in the pics, I don't see a nut and none of the pics show the head of the screw. But if you says so.....

      Tire psi

      Thanks for all the help so far!   I did try right from 2026 right down to 2021, and only from 2023 down lets me select the option for tire psi change, but I get the vehicle not supported error!   I'll definitely try it under Chevrolet after work today, and I'll get the sensor number from gm for my truck tire sensors. And I'll let you know if it works for me under Chevrolet!   And if that doesn't work, I'm going to guess that what @Atlas said about maybe I have a different body control module could be true!

      2010 Avalanche 5.3 not running correctly after engine swap.

      From where I'm sitting this sounds like a compatibility problem. I'm assuming the 2007 was a 900-series truck, and not an 800-series (they were sold side-by-side in dealerships that model year), since it starts and runs.   This is why I HATE post-2006 vehicles. Everything becomes a huge problem when you try to keep the thing running for longer than the manufacturer has designed it to.    I can't remember when Global-A architecture started - either '10 or '11. For your sake, you had better hope it's '11, or you're going to be spending some BIG money to correct this cluster-eff. That's something you need to find out before doing anything else. You may have several computers bricked ... but the fact that it runs tells me you MIGHT be ok here.     EDIT: Just did a quick refresher. You're screwed. This is Global-A. The 2 systems are NOT compatible in the slightest. Once you get the correct engine in there that IS compatible, you're going to need to see how many computers are locked. Absolute NIGHTMARE to straighten out, too. Your buddy might be better off cutting his losses and finding something else.   Welcome to post-2006 vehicle electronics. This is why I quit the industry, and drive nothing built after 1994. This stuff takes all the fun out of wrenching!

      True, hard to say what differences there may or may not be between Chev and GM as well as a production year or mid year part change either.    I just found it odd that under the Sierra choice on the Autel that many of the last few years of production year did not include the choice of changing the tire pressure but if that is an Autel thing or a GM thing as to why the choices were not there. Knowing what tpms sensors are on the truck should give some guidance into which choices on the tool even make sense to try as I wouldn't give up just yet with the tool but I guess he will see what if anything he comes up with if he finds out a bit more info and tries a few more things on the Autel.
