ISX Fuel Shut Off and Warranty.

I just had my fuel shut off valve replaced at Cu****ns under a warranty I got from Ry**r.

I got the running on issue the first time I tried to shut it off, I took it back and they said they corrected it, it was a bad electrical connection and it stopped running on.

We used the truck for one run two days later and it started to run on again. Took the truck back and now mysteriously I have an injector problem.

This truck never "ran on" prior to the FSOV being replaced. It was originally in because the engine lost power without throwing any codes.

The Ry***r warranty has now expired during that week and Cu****ns wants to bill me by saying it is a wonderous fluke that it now has an injector problem.

The engine starts great, idles smooth as silk without any ramping up, no smoke, great fuel economy, nothing in oil, no blow by, the engine was rebuilt and I mean everything by Ry**r 106,000 km's ago or 65,000 miles ago, new factory injectors as well.

This engine started and stopped thousands of times without running on and since the FSOV replacement, to the first hour after, it runs on 3 out of 4 shut downs.

Any ideas of what I could do? They billed me over $1100.00 and would have billed me an additional $3000.00 if I got the injector replaced.

 

It is not that it, is that they are trying to pad their bill by saying something else is going wrong.
Anyway I got the truck back and manually disconnected the power wire and it ran on, then I did it with the engine off and checked to see if the solenoid was working, it did sometimes. I took the solenoid off and examined it then put it back in and now it doesn't run on anymore. I just followed the instructions posted in another thread, now the truck doesn't run on, at least not the last 25 shut downs.
Think they will refund my money? For the injector diagnoses I didn't need?
$1134.00 to diagnose the injector and they didn't do a cylinder cut out test or a fuel pressure rail test.
I am getting over 7.0 mpg in mountains, BC mountains!

Yeah, I needed that $3000.00 injector bill added on, never thought a reputable dealer/engine company would stoop to padding bills. But then I never liked dealers anyway because they treat drivers and OO's like we are idiots and they don't need our work.

 

Actually the Ry**r warranty was really good with a couple of exceptions.
What my issue was that the engine manufacturer installed a new FSOV and then didn't want to warranty their work or part.
Ry**r spent thousands on repairs, it is just with them they do limit what they want the shop to do so it actually cost them 2X as much to get each thing fixed. I found their warranty, the 30 day bumper to bumper very good but it was time consuming to get things fixed.
I complained to the higher ups at Cu****s and I got the diagnostic fee re-imbursed. I think I got lucky, how many guy's/gal's are getting mis-diagnosed just so a bill can be padded.
I used to be a HD mechanic a long time ago when you had to use your head/brain instead of a computer to figure out problems. As stated, how does fuel get to the injector?

 

Not saying individuals, as preferred/an environment by most shops now. Use of the computer as a tool is great, they just are not infallible.

Quite often what is the first thing that happens at the shop? They plug in the computer and if some faulty sensor gives off a reading in some shops the most expensive thing is changed FIRST and the little $150 sensor last or not at all or at the same time.

I mean why would the shop, using the computer, not do a cylinder cut out test to check %'s before doing the more expensive injector test?

At any rate too many shops don't hire Heavy Duty Mechanics, they hire Technicians who rely solely on the computer for diagnoses.
