    Still in the shop. It is one month away from the end of the 5 year warranty. They finally called and offered us a truck so we took them up on that. I am guessing this will close to 2 grand. Found out tooo late that we took it to a chev shop not known for diesel repairs.

    Still in the shop needs 8 injectors none available in US apparently everybody knows there is a shortage and keeps theirs hidden.

    Very unlikely all 8 injectors failed all at the same time...

    Sounds like they don't know what it needs and are going to try injectors, cause like diesel tech said seems odd that all 8 fail at the same time and 06 isn't known for injector problems,
    Could be a short in the harness , all years have that problem

    If they are paying let them replace all 8 but it sounds like they don't know what they're doing... Loss of rail pressure can cause a no-start without setting a code. That can be caused by a bad injector but they can be individually pressure tested... Also, the cp3 can be at fault here. They need to check for fuel from the return line to verify the gear pump is working - or that fuel is even reaching it. If that checks out then the fuel control actuator should be tested/replaced. The FCA is computer controlled and is what allows fuel into the rail at the necessary pressure (around 5000psi). There is also a cascade overflow valve that is mechanically controlled (spring) that could fail and keep fuel from reaching the high pressure piston pump, rendering the cp3 useless. If they are diagnosing with a scanner they may be barking up the wrong tree...

    Well we were told today that it will one more month before they can tell us when they will get the parts. They are considering putting in a new engine can you image that:hammerhead:

    Get it out of there and go to a real diesel shop. I had a an 08 - on interest, lost power and finally pulled over cuzz it was dead. Only had around 20K miles. When they changed oil last they never did the fuel filter - keep this mind - now i call - they say injectors, fuel pump, try pumping the pedal for fuel - they really had no idea. I called a friend of mine whose dad is in the repair business - he asked if I had tools - always got tools, he ask if I can get a fuel filter - sure a napa store a block away - replace the filter - started right up. So back to the GM shop - they had no idea and neither does your shop - get it out!!
