On sat my engine shut down on the interstate. Tried to restart and it would start and shut down right away. Ended up having it towed to Orlando Freightliner. Even though they are open 24/7 they couldn't start on it til mon. Yesterday they changed the lift pump with no difference. Then they changed the injector pump ($$$). Wouldn't start right away. The tech (?) worked on it for awhile and it finally started. After 10 min it died again. Been doing that all day today. One time it ran for awhile but every once in awhile the engine would "stumble". I am still stuck here! Any/all advice would be appreciated. The tech is really trying but he has only been here for 4 months and before that he was an auto mechanic.
Thanks

Well, it's obviously not getting fuel. That can be lots of things. You may want to consider Turbo Diesel Register. Mostly a Dodge P/U site, but also covers any B Cummins engine in anything. I have an older B5.9, but can't help with your ISB because I know nothing about the electronic controls on it.

You have to join to post and it does cost, but it's probably more than worth it for the expertise you'll get there. Sounds like your tech may be trying, but has no clue. And he's just been throwing parts (and your money) at it instead of diagnosing the problem.

Sounds like it's sucking air into the fuel line/supply. I'd check that the fuel filters are tight and follow the fuel line to see if it's rubbed on something. Next I'd put a clear tube in the fuel line before the injection pump to look for air bubbles going by. I always try the simple things first but you are at the mercy of the shop. Once they find the real problem I'd make them put your old injection pump back on at their expense. Not going to happen but maybe they will reduce the price on the new one.
This post is my opinion (free advice). It is not intended to influence anyone's judgment nor do I advocate anyone do what I propose.

Just a few thoughts:
In your previous post you mentioned the generator ran fine so that pretty much rules out bad fuel but just to be safe had you just fueled up?
Did they change the fuel filter(s)?
Also check for any loose fuel line connections at the fuel transfer pumps, filter housing(s) & injector pump. Could be sucking in some air.
Check the electrical connection at the fuel shutoff solenoid on the injector pump.
Lastly, I hope they are not charging you for the parts they seem to be just throwing at it and hoping they luck out and find the problem.
Good luck and keep us posted.

You know on second thought you could have gotten a bad load of fuel (water contaminated).
The genset fuel pickup is up off the bottom of the tank and would not pick up any water that had settled to the bottom of the tank.
I'll ask again. Did you just fuel up?
A bad load of fuel can shut you down within a mile or two from the station depending on how contaminated it is.
First thing I always ask myself is what has changed recently?

That vintage had issues with some oil pressure sender units. A bad sender will tell the engine it's oil starved and shut it down. Might be worth checking...
There are 24 hours in every day - it all depends on how you choose to use them.

Yes that is what I was thinking too! They should have check with fuel filter first. It is possible that you got a bad fuel. When is the last time did you drain water seperator?

Rock2, shouldn't the ECM be setting error codes if the oil pressure sender were indicating an oil starved condition? For that matter, there should be error codes for many conditions including water in the fuel (at least that sensor is there and should work).
Have they put a diagnostic computer on the chassis or are the mechanics just guessing what is wrong based on their experience? I hate to say it but it is a situation like this that convinced me to by VMSpc in the first place. Being able to monitor the engine real time is a plus but knowing what codes are set and when could be a real money saver. Just my $.02 worth.

Just received a "Cummins Campaign 0805" notification about a problem with a fuel line bracket.
The notice states that the "installation of a new bracket will help prevent excessive fuel line vibration."
Don't know if this may include your engine, but it may be worth looking at.
Good luck.

This campaign only applies to 2005-2006 ISC/ISL engines. late 2006 engines had fix installed on assembly line but need to call Cummins Distributor to check your specific engine. This is an IMPORTANT fix so don't delay getting it done. You don't need to have the bulletin to have work done.
