^^^^ That's a good thread summary, right there.

...at the end of the day....

Just got back from another 2-week vacation.
Under advice from this forum, I had the alternator replaced (chirping at shutoff) which cost me over $500.
Imagine my surprise when I get to the first stop on our journey, and it's still chirping like a canary on steroids! I blew $500 for an alternator that probably didn't need replacing in the first place....

The upside is that since this was a relatively "flat" trip with few hills...I was able to drive it in MANUAL mode and avoided any fuel-related codes....just a constant chirping.

Here is where the "end of the day" part comes in: I have grown to hate this vehicle.
I've never felt that way about any other vehicle I've owned...not even the last GM that left me stranded...but this one has broken my spirit AND my bank account...so she is on Craigslist now. I'm done with diesels.....the $5000 it will cost to repair it will buy a LOT of gasoline...I don't care if I get there ½ hr later than everyone else.

For the record....the mechanic who DIAGNOSED the injector failure was a GM diesel tech.

In all honesty, it sounds like you made a good choice since you where unwilling to try even the easiest and cheapest of the advice given to you here by these long time DM owners. Good Luck!

I get the feeling that we could have this thing running flawlessly in a day doing what hook has suggested to a "T".

You can lead a horse to water but you cannot make him drink.

He is correct, he should get rid of it. HE is much better off with a gasser.

Personally I would never go back to gas for towing.

When I cross the tallest hill in my part of the world (the bridge on I-10 crossing the Mississippi river bridge into Baton Rouge my old Ford gasser would pull it, but by the time I got to the top I was in 2nd gear with the engine screaming doing 35 MPH.

My LMM does drop a gear climbing the bridge but I am still doing 62 MPH in cruise control at around 2200 RPM...............SWEET!

Well, I spoke to ANOTHER mechanic today and he seemed to be aware of the "bottle test" and FPRV....as well as the fuel line issue, although he says he's never seen an issue with them.

The previous dealer that I brought it to, turned out to be a shyster....they "CONFIRMED" that the squeak was coming from the alternator, yet the squeak remains.
They diagnosed that BOTH of my horns stopped working simultaneously and quoted me around $500 to replace, yet when I crawled under the vehicle yesterday....surprise, they were simply disconnected. When I reconnected them....they BOTH work again.
Therefore I have ZERO faith in their diagnosis that all 8 injectors require replacement....I will be speaking to their service manager, although I imagine that I'll get the usual corporate BS and runaround....

As I was driving to this other mechanic....she threw ANOTHER code at me....as if to confirm my decision to sell this POS as soon as possible....P0403 EGR issue.

Can't wait to get rid of this.............................................. .

Ya have to realize, out of the millions of Dmax produced, they are highly reliable....and they just don't break down....much.

As a result of that ^ AND it being a Diesel, there just isn't much experience out there with shops....again, they don't break down. It's hard to find an experienced repair person who has tackled a similar problem in the past.

So with the DF archives we have, compiling real world experiences from a User standpoint, many times your solution found here is right on.

But trying to find a shop to act on this info.....scarce.

Just hope you never have a problem with the Allison. It's probably the most reliable item on the HD.
Trans shops, they don't work on transmissions anymore like in the past. They just pull and install off the shelf remans....that come with a 3rd party warranty, which also covers their labor if something goes wrong.
No liability on their part, they're covered regardless.

Try and source an Allison certified repair shop on their site, good luck with those. They're all shops handling large MD and HD trucks, where they just roll up under 'em.
They don't have any lifts in the shops, never use 'em.
So they can't work on your small, low to the ground HD.

A good reliable trustable mechanic is what you really need. More than likely you will find that the codes are related. If its not building exhaust back pressure, it can start kicking EGR codes. Being as the last dealer or someone started unplugging stuff, I would not be surprised to find other practices to entice you to keep bringing it back. $5,000 or mr for injectors, $500 for alternator, $1,200 ( or more) to fix ear and all they do is plug something back in or change a cheap hose.

Just like any other vehicle out there, sometimes one does have issues. Look at the total number of miles of experience with the Dmax on this site and the number of people with extensive repairs. I am on my 4th Dmax racking up 178k+ on my first one (still have her), 203K on my second one (113K by me), 23K on the 3rd one (traded because I wanted a different color), and 12K on the present one. The one with 178k on the clock has been hydrolocked and still made the 150 mile trip home from where it happened. Got lucky and was just above idle when it ingested the water. Drained intercooler and let water drain through the rings, fired it up, finished the 4 hrs of work at the deer lease then drove home. Got lucky, had I been turning high RPM she would have needed a block, instead 1 piston, 1 rod, and 1 bearing were the damage. Total number of times in the shop for all 4 trucks under warranty and other than maintenance or stupidity is less than 15 (counting oil changes).

Good luck with the sale. Hopefully it goes to a good home.
