well no easy way to drain the tank..

You could pull the fuel filter and turn the key to on it will make a mess Btw. but big tote or something underneath to catch it.

not to sound overly naive but does putting the diesel additive that cleans the fuel and moisture help any?

Re: Engine staring issues

Had Autozone check the code on the check engine and it came out as P026D which I'm still looking for online. If there was gas in the tank, which I'm still not sure there is, would it display a code for that? I do have spare fuel filters on me but don't want to use them yet if there's an issue.

P026D is Injection Quantity Too High

found on duramax forums

Engine staring issues

I'm in the process of draining the fuel and replacing the two fuel filters now. Going to drain everything to the bare minimum then top it off with a new fill up hoping that takes care of things

Engine staring issues

The tip above about pulling the filters and Turing on the pumps via powering it up has been a great help and honestly not that splashy.

Since it does run once started I don't see how a complete system flush would be any better. Whatever tiny residual there might be left shouldn't matter. If something broke guess I can't do much about it

Re: Engine staring issues

I have a few questions:
  • I saw there was a message in the cluster, "Service Electronic Braking System"?
  • Were the fuel filters dirty? Did they smell like gas?
  • Did the engine/transmission ever get extremely hot?
Try plugging in an OBDII Scanner, and check actual fuel rail pressure vs commanded fuel rail pressure while in RUN

The message in the cluster is only there during this start as is another message about backup sensors however once started everything works.

The engine and transmission have never run hot. I've checked everything quite often during all of this. As for the filters I am picking up a gas odor now that they have been pulled. I really don't know what to say I don't know if it was the tanks or me but as with most failures in life, I'm the constant. I pulled he filters and drained the tank down to so little I wasn't sure I'd make it to the station. Here are the filters. That I pulled Attachment 72377
Attachment 72378

How does the computer work as far as logging codes and issues? In my jet the Mx guys can hit a couple buttons and pull a log up on the screen. Is the jeep like this does it log everything? If the issue appears to be resolved with the check engine light go away or does it take a technician to clear the codes? Now that I've drained the system and topped it off with fresh fuel I toss an additive in it to hopefully help take care of any other issues.

Re: Engine staring issues

After the flush. Engine light still remains and engine doesn't quite sound 100% however there is already a very noticible difference. It now starts normally.

I apologize. I didn't save the filters or pictures. I don't know why Tapatalk didn't work. The filters were a dark to almost black brown. There was a somewhat glueish looking residue very sparsely on them. The ones I found online a while back did fit perfectly however they do not appear to have the same build quality as the mopar ones. I don't know how often people replace them but it was my first replacement in roughly 15,000 miles. While they were very dark in color I'm not sure I'd go so far as to say they were ruined.
