Noticed a delay in engine starting up, would roll over a little longer than normal the past week or so, thought it was the drop in temperature or maybe due for plugs at 60k. This morning it was -25degC/-10degF and it would just roll over and not fire. Tried several times, no go. Went back out 15min later and it started, then engine light came on. Plugged in reader and had p1682 code. With it still being under warranty took into dealer and had them make record of it and to diagnose. Well I got a surprise when my total was $59.59 out the door for diagnostic check, parts, and labor. 3yr bumper to bumper had expired, still has 5yr powertrain. This issue NOT covered under warranty.

 

Quick summary:

2014 GMC Sierra 1500 5.3L 60k

Tech comments:

verified complaint, no start, vehicle eventually started, scanned for dtcs, p0689 engine control ignition feedback circuit low voltage, p1682 ignition 1 switch 2, found bulletin #PIT5253B, replaced relay #70 ecm as per bulletin, also checked battery, battery tested good at 625cca, cleared dcts, all ok.

Parts:

1.00, 13595508, Relay, $11.99

Put half a bottle of synthetic slick 50 in the motor oil. It will leave enough lube on the motor parts to start. This zero weight oil is leaving nothing on internal parts....excessive amp draws from battery on cold starts and not good for negative and positive battery leads.

 

Try it. Mine starts MUCH easier now.

      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

      By jgaudet99 · Posted

      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.

      By Jsdirt · Posted

      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!

      Tire psi

      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.
