So let me see if I can get this all in here and I apologize for the story.
Our 07 LTZ 5.3L avalanche is about ready to find its way to the scrap yard cuz well I'm over trying to figure out this problem.
Last week, (while driving it) the ABS, traction control, brake light and stabilitrak error all light up the cluster. We got to our destination, shut it off, left 2 hrs later, truck started fine, reversed out the driveway, drove another 20 minutes, cluster still lit up. About 10 minutes into the drive we realized all the lights were on, but none of the gauges were working and the gear panel was still registering we were in Reverse.
Get to where we need to be. Check to find the reverse lights were infact still on. Shut the truck off (don't know what we were hoping for as we knew it wouldn't start in reverse ) reverse lights stayed on, Turning the key, gave power to absolutely everything, but the truck wouldn't start.
Hubby called his mechanic friend (he's a bit of a back yard mechanic himself) the friend told him a bunch of fuses to check, after playing with the fuses, the reverse lights turned off and the truck would register P & N with a slight delay but still wouldn't turn on, after replacing a fuse, we are back to it not registering.
So we took to the internet and found this gem, we went threw forms upon forms trying things.
We have ;
-Replaced the PCM
-Took a test light to the fuses and the fuse box itself
-Replaced the neutral safety switch
-Checked all ground wires
-Tried using the feed line things (idk what they are called) with another battery to basically bypass the trucks battery connectors
-Hubby can cross the starter to get a reaction and get a reaction from the relay but it still won't start.
- Tried holding the key in run and crossed the relay
2 mechanic friends are totally stumped, one says he could hear it slowly trying to start over, (but he's the only one to hear that ) and we are annoyed, of course over the period of doing this the battery has died countless times and though boosting it, we are going to swap it out with a newer battery in hopes that it just can't reset the moduels but like all our other hopes, I feel it's wishful thinking.
Any suggestions or ideas are greatly welcomed !
