Update: COVID Knocked me on my duff. Physically and financially. I can see the light at the end of the tunnel and it is apparently not a train. However, I am unable to get into my GMTNation Account, I tried contacting the registration help, and it didn't go through. So I re-registered and am now VM. YEET!
Below is a summary with video of the last time it ran.
The only code I can get it to pull is a P0412 and I get zero, zip, zilch ignition now. I am hoping that by adding in the extra info, adding in the video of the very last time it ever ran(that sort of backfire video is the last time any cylinder ran).
At any rate:
I had a Chevrolet Trailblazer that no matter what, I could not get it to run. Has 60k miles on it.
I did not know that the dealership had used it as a "take-home" vehicle for employees. An employee wrecked it. Despite the dealership, Ware Chevrolet of Blairsville GA selling it to an individual in NC, where by law they must disclose any wrecks or damages, Ware did not.
The vehicle ran fine for 60k miles roughly. Then one night I had to drive into a field on the farm(dead of winter, grass was tennis shoe tall) and NO BRUSH. I asked some hunters who were irresponsibly shooting towards my home, and were trespassing, to please leave. Next morning I attempted to start the car, it was pulling up to 192 codes on an ACTRON type scanner, and 140 codes on a Tech2 Clone that I purchased.
I tried to replace the ECU twice, as that was advice from the dealer techs and forum wizards. I had the Tech2 for the CPS Relearn. No luck. You could try to start it, it turned over, no ignition, random codes- never a moment where there was ignition and all cylinders running - NOT EVER.
I thought I must have a ground wire disconnected somewhere.
I then paid for it to be hauled to Ware Chevrolet. They kept it six months, and they could not diagnose the problem. They continually had to open tickets with GM. Finally I was charged over $3000 for a new PCM/ECM, programing, the central ECM harness was no longer holding steady to the PCM/ECM, so they had rewired it with a new Delphi connector but did not address the problem that caused the center ECM harness to potentially come loose. I had just put in a new GM factory battery into my Trailblazer before bringing it to them, and they said it was bad, disposed of it without asking, and replaced it with a new battery. Tires had been fine on the truck before taking it to them. Suddenly 1 had wires sticking through it, and another would not hold air- not a problem loading it on the rollback when it was delivered there.
They offered a rebate if I would replace the tires. Tires
WERE NOW DEFINTELY BEYOND ANY SAFE USE.
So ready to leave at $3600 later, applied to get $200 back on Hankook AT tires.
I went to pick it up and was told that because it had old gas in it, I needed to run some SeaFoam, top off at a local store that keeps 93octane E0%, 100% gas, as the old gas caused it to stutter.
I did just that, it still stuttered.
I drove it around for a few trips- 125 miles at most, more likely 50-75 miles, probably actually less. It had a stutter upon acceleration and a stop lights like it was going to die. Their service department would not help me and I asked about bring it back in, "We're simply too busy." Feels real good as the manager of Ware Chevrolet and it's owner bother live less than 8 miles away
Drove it around and on a four lane it seemed to want to almost stop, and one day it did and I was nearly killed except a transfer truck driver pulled a miracle and a prayer. Couldn't get a flatbed wrecker to come get me, so I tried the key, it cranked, it did surge, I drove home with emergency lights on.
I got home, into the drive way, it died again. I put it into neutral and I rolled into the spot where I parked it. The COVID plague hit, I was now unemployed, and no more money to throw at the Trailblazer.
And there was the mystery that the ONLY CODE I COULD EVER GET IT TO PULL EVEN WITH A TECH2 WAS.... P0412.
Here is the last "startup with ignition":

If those won't work for you, please let me know.
Any ideas ? Now I am back to good old charge the battery and then I will hear an attempt to fire and then it just turns over with no firing at all. Spraying ether doesn't really do anything different, no ignition.
I have no idea how to take a fuel pressure reading or what tool I would need to do it on a 2006, but again, I just have a P0412 code and the service engine soon light- nothing else.
The 2006 manual is for a 5.3 V8 and doesn't cover the 4.2L in any way, shape, form, or fashion. So even though I bought a quality $200 fuel pressure test kit- no idea whatsoever on what to do with it. I cannot even find a rail with the green port to use it with.
If anyone has any ideas, has dealt with anything similar, please let me know. I am somewhat financially recovered from COVID's shelter in place order . I have some funds and wanted to see if there was a chance I could get this vehicle running, as I honestly need to get it running.
I realize this is a stupid question, but is there any chance I could do a engine swap on this truck ? I have no emissions or anything like that. I prefer to fix it the correct way the factory would, but after WARE Chevrolet went from "It's going to run $1200 worst case." to "We're having to open a case with GM Diagnostics" and I'm asking how much more is that going to cost "Should not add to the cost significantly." to "Your Trailblazer is ready, $3000 plus new battery(won't hold charge but the one that they replaced and was GM and in warranty would) and it will need new tires. Combine our tech time plus having to open GM Diagnostics case, and it adds up very quickly. Sorry for the surprise sir. VISA, MC, Check ?"
