check engine light and stop engine light came on. truck will not start. it flashing code 4-8-2. any one know what the problem is?

mtr510 if you have a lap top you can go to the cummins web site and down load a program to read your engine computer. You will have to go to a Cummins dealer and buy the cable that fits your truck a lap top.
If I remember correctly its called Power Spec for Cummins . I looked up the cable for my Cummins 500 it was $85.00. Currenlty not in stock for me but will be monday. Hope that helps.

You need more than the cable, you also need the Inline adaptor from Cummins and I think those are around 400$.

I have a Cummins factory manual for the ISB engine and it has listed code 442 and code 488 but not code 482.

The simplest thing to do is to call the Cummins Help line (1-800-DIESELS) and they will tell you what code 482 is.

I think the code 4-8-2 in a cummins n 14 would be low fuel pressure
you may have a fuel restriction from the tanks to the pump

482 is a low fuel pressure code. I looked it up on Cummins QuickServe. If you can produce an engine serial number, I can give you more precise information.

i change the fuel pump and it started right up. now i got 3 active fault flashing code 2-3-5. any 1 know what this is?, also i keep getting the low coolant warning. coolant is fill up.

For the Cummins ISB, 235 is the code for coolant level sensor. Perhaps your sensor is defective and indicating low coolant level even if the coolant level is full.

Whenever I get a code I call the shop that does my regular maintaince. (It's a Cummins shop not a dealer) They have al my engine info onfile and the service desk can usually tell me within a min. or two what the code is..

There are too many codes from what I understand to print them in an owners manual? Though I seem to remember my old Detroit having the codes there.... Oh well...

The cables and adapters are pricey, I would rather make a phone call than spend all those dollars on somthing I hardly ever use..

Yes, adapters and software are EXTREMELY pricey... Cummins for example charges our shop almost 1000$ PER YEAR to run their software (INSITE) and the adapter and cable run another 1000$ (NEXIQ USB Link). Less expensive alternatives exist through tool companies like Snap-On, Mac Tools, OTC, and many more but right now different manufacturers differ so much in codes and other things that the cheaper alternative sometimes (lots of times) leaves you in the dark or even worst misleads you in diagnostics.

Here's what's even worst, manufacturers are starting to build a standard, and changing all their codes over to meet that standard. Detroit started using this standard in their EPA 07 engines, and other OEM's will follow shortly. I'd wait at least until this is fully implemented before making an investment in diagnostics equipment if I was an Owner/Operator.

Like it was mentioned before, the best thing to do is find a good shop that is willing to help you out and give you that information, often for free, over the phone. Lots, if not most of shops will do that if you talk to the right person.
