One thing that didn't jive to me, was dodge claiming a $7,000 to $10,000 repair bill for Pump, and Injectors? Jesus, how much does the whole motor cost?
I'm not sure exactly who you have called, and spoken with, but if you have not done so yet, I'd definitely give the Zone office a call, and talk to a factory rep.
Have this person come out to the dealer in question, and all of you are going to have to get your heads together. About all you have to go by, is the service bills-sheets.
You'll have to mention that you never got a WIF light come on, so how were you supposed to know? Does the service write up confirm that?
Sounds to me, that this Dodge Dealer likes placing the blame on their customers, and are ignoring a legitimate warrantee claim.
Either way, it's not them that lose money, they get paid for the work one way, or another.
Back when I bought my '90, the Cummins Engine was a great engine. It was put in a quite shitty, inadequate, outdated truck though.
The newer design truck has many improvements, but over time also, the Cummins 5.9L has also become more sophisicated, with lots more PITA "computer crap" on board.
My '90 Cummins had nothing on it. Just a Cold Start Advance, and Anti-Lock Brakes. That was the only computerized electronic device under the hood, nothing else.
I never had a problem with the Engine, it was always everything else.
I wish you luck getting this all resolved with your truck. Remember, keep a cool head, as getting nasty with the reps, etc will surely get you nowhere. I understand, I'd be fuming mad myself probably at the lack of concern, and runaround by the dealer, but if these issues are not handled properly, you wont get anywhere with them.
It may even be a good idea to contact Cummins themselves, and speak with some people about this. Cummins doesn't like to hear about problems with their engines due to a problem of a dodge manufactured part. Mark
