Any Help will be appreciated

Hi Everyone

I hope someone can shed some light to assist me. Any Advice that will help

In South Africa Chevrolet or GM does offer support that much anymore and to Find good Mechanics or Programmers is either really expensive or they just outright want to make money on everything and that does not guarantee you a fixed product

I have the 2014 Chevrolet Trailblazer 2.8LTZ that was Manufactured in Thailand according to my knowledge along with the Holden Colorado 2.8LTZ or D-Max.

My car broke down first Mechanic Said it is Fuel Sensor, Replaced it. Nada car did not want to start.

He sent it to Auto-Electricians to see if they can find something electrically wrong. To my surprise they said an IC on my ECU popped. Believing them I went on the hunt for an ECU, even more to my surprise they told me I cant replace only the ECU I need to do the whole lockset.

Well a lot of money later I got a complete set second hand off a car that was crashed from the back. Installed it and again as you guessed it. The car did not start.

They gave up and still invoiced me for the time spent, Next up was taking it to the mechanic again he referred me to a diesel specialist. Immediately without much fault finding he said pump and Injectors, Wooooowwww that was a lot of money but again the car did not start.

So now I have given up on trusting them and I have basically pursued a new career as this is a brain challenge

And off I went I found 2 of my valve rockers was broken..... Afreakingmazing.

While I was throwing money towards the problem took out the engine stripped marked labelled and did everything according to a Holden Colorado Workshop Manual sent the engine for refurbishment and fitted it back in the car.

So still the car did not want to start probably because of all of the other stupid things everyone else was trying to do to the car

We are now at the total cost of R65000 or $3725 odd dollars.

So I went to buy an Autocom Diagnostic machine and is now learning this trade

This is now the last remaining fault codes and I am busy doing wiring tracings as I have time over weekend in the garage

so you have no comunication to 5 different modules and also an error for low batt power . if it was me i would re install all orig modules if you bought a new set and then scan car with them installed .see if you get all same codes. if you do then
start thinking about power breaks or short circuits. check or disconnect lights one side at a time another thing that can cause all sorts or coms problems is bad earth connections most ecu are grounded to the car on a bracket
so just hot swapping to another module without grounding can cause no power no coms. another thing that sounds crazy but even incorrect car radio power connections can be a cause that top code p2264 sounds like it could cause the errors
shown below ...hope it gives you some new things to check
