8000 miles and injector problems

First diesel truck and I wish I would have heeded the advice I saw on here and not bought the truck. 8000 miles in and Iím having code po1cf.

Some research on here shows itís a known problem. Oh joy.

This is my work truck when itís down Iím not making money. I drove my ecoboost ford transit van like I stole it every day and had only a few problems revolving around joints. I regret buying this 50000$ paperweight also known as a Duramax.

8000 miles and I have an injector code. If I could go back in time I wouldnít buy this truck.

This sucks.

Next up the three hour process of unloading the truck so I can take it in for service. Iíll reload my beat down transit van and put it back to work. Iíll keep this post updated but as of now itís a real ing disappointment

Sorry to say but if you're here to piss & moan about buyers regret on a Dmax Forum you probably won't get much sympathy. It sucks but it's a piece of equipment, they break. If your ecopoof was so awesome I guess you should have bought another one of those

I still have the ecoboost waiting in the wings. Tomorrow morning Iíll be loading it up. Donít tell me 8000 miles is an ok Mileage to have problems because itís not. All vehicles have problems I get it.

But dam itís only had one oil change.

I know all about equipment breaking I own and operate a fleet service company and 5he Duramax is my paycheck.

I assume this is a newer truck- 2017+? There is a known problem with the electrical connections to the injectors. I've really only seen it reported on the '17s and '18s. Apparently a manufacturing / design problem with the connector. GM is well aware of it but I'm not sure what they are currently doing to fix it.

Yes itís a 2019 Iíve got an appointment today at dealer, but from my research it appears they donít have a fix for this. I am going to change the fuel filter this morning.

They were replacing injectors on them for a while but think they figured out that was just a temporary fix. I know one of the guys on here who uses his truck to tow commercially has discovered that cleaning the connectors works. He has over 250k on his '17 so I'm guessing he knows what he's talking about.

There is a fix-it kit from GM to re-pin the connectors. I just cut mine off, and used gold plated LBZ plugs.

The truck is still under warranty. Take it in and let them do their thing. A forum diagnosis could be way out in left field somewhere.
