I have a new 131 mile, less than one week Silverado Trail Boss 5.3l and the truck would not start.

Four tries with the key, a remote start attempt and just engine cranking.

Called On Star and asked to have it towed.  Sat for about ten minutes and tried again.

This time it started but a check engine light was set.

I had it towed anyway.  Dealer said the fuel pump module was bad but truck is running and they cleared the code.

GM agreed to replace the module.

Anyone else have a bad fuel pump module?

Well it looks like no one else has this problem.  Dealer has the part on order.

Truck is running.

Word for word same issue except at 1,600 miles.  Not giving me confidence in the truck.

Module was replaced and the issue has been resolved.

Check engine light came on my new 2020 Trail Boss at 950 miles. Diagnostic test pointed to the fuel pump. The dealership is replacing the fuel pump. I'll let you know what happens.

I had that issue but didn't know it. Had it in for the hard shift. Code came up at the dealer. So fuel pump was replaced under warranty took them more than 2 wks to get part and fix.

2020 trail boss 6.2 175 miles on it.  I just drove it home from the dealer and it wouldn't run the next day.  They hauled it back to the dealer yesterday and waiting to hear the results.

I have a brand new 2019 GMC SIerra Elevation with the exact same problem.

Dealer fixed and replaced the pump but now the pressure sensor is being replaced as it has now thrown a code this weekend.

Will let you know how this goes.

I just received my truck back and they replaced the fuel control module.  Hopefully it holds up.

I had the same issue pop up after 500 miles. My truck has been at the dealer since May 7th and still no part. About to make my second payment on a truck that hasn't been in my garage for just under 7 weeks.

      Where is the Ambient Air Temperature Sensor on a 2021 Chevy Suburban?

      By newdude · Posted

      Yea that's pretty normal to be off a few degrees.  Usually 2-4 degrees from say a weather app or thermometer.

      Where is the Ambient Air Temperature Sensor on a 2021 Chevy Suburban?

      By studly · Posted

      I just replaced the ambient air temperature sensor.  Easy as pie. I simply had to remove about 10-12 clips on the plastic cover over the radiator and remove two T-10 torx screws on the hood release lever to liberate the cover (Amazingly, none of the clips broke.  All came out and went back in with zero problems). Once the cover was removed, the temp sensor is easily accessible. The sensor cable snakes through a few guides and can be pulled out for even easier access to the sensor. I was able to work the sensor out of the mounting hole.  There is a red sliding catch on the plug that must be pulled back to disconnect the cable.  The plug was quite tight.  I had to use a screwdriver to pry it out. I plugged in the new sensor ($6.45 from RockAuto), snapped it into the mounting hole and re-snaked the cable. I put the radiator cover back on and reattached the lever arm to the hood release.  All done!     I started up my Suburban.  The temperature read 82 °F. Other thermometers at my house read 80 °F.  Close enough.  It might be reading high as my vehicle was sitting in the sun.

      Wow I'm in a pickle. (Broke down truck) and a story.

      That one looks decent for the price   BUT..I want something that also supports OBDI/1.5. A lot of the prosumer-grade scanners don't have legacy support in order to keep costs low. I believe the Autel does if you go higher end with them.   For fun, I reached out to a local Snap-On rep because I was interested in the 2600. $1895 MSRP, says he can do $1595. That's still a lot, but then again, that's not a horrible discount for just asking out of the blue. Could probably do better if I was a regular buying off his truck, but I'm not.   Not sure if I mentioned but I didn't realize with USED scanners from Snap On that you need to make sure a) the serial number isn't flagged as stolen. On the newer ones, SnapOn can remotely disable the device if it's flagged in their system. And, customer service can tell you if it is, if you're thinking about buying used. B) Make sure it's paid off. If the seller still owes money to the truck or if they financed through Snap On, the device can be remotely disabled until the balance is paid. It's less clear if SnapOn will tell you if a balance is still owed; I didn't make it that far with the used model I was considering. I did read that SnapOn has no way of tracking any "truck financing" deals between the SnapOn rep and buyer, only if they financed through corporate. So there's that extra caution needed.   Still waffling on whether I go with a ~$500ish Autel/TopDon or spend bigger money. The value seems to be in the prosumer brands. I'm not giving them enough credit TBH, actual production repair shops use them daily BUT I'm still allergic to certain kinds of underdog products trying to unseat American companies with solid reputations. SnapOn's scanner isn't wholly made in the US, but it is assembled here and they have US support and probably the most proven/ robust legacy support.   Something to think about. Value, or principles? There's a $1k difference.

      Winter Returned

      By Atlas · Posted

      I'm thankful to live where we don't have extreme weather. We might all be blown to smithereens when Mt. Rainier goes, but 80 is warm enough in the summer and I can generally count the number of hard freezes in the winter on one hand. The cars here don't rust and they don't get sun-baked, either.   We have finished off many of our average 52 days of "clear/sunny" weather, though. Sunsets are coming earlier, the nights are a little cooler. It's right around the first week of September when we get our first warning that summer is coming to a close with overcast skies and the start of "hoodie weather" temperatures during the cooler parts of the day. By October, it's usually time to ditch the shorts. By November, it's mostly raining.
