I am a master diesel mechanic by trade and currently own a shop. “Old diesels” yes, new diesels not all of them. Many do now have computerized engine management systems just like gas engines do. That’s how they are getting 8 MPG in the new semi trucks loaded at 80k pounds at 75 MPH. But with some minimal mechanical refitting including the starting circuit any diesel could be made to run. :)
“Escape Pod” Ahoy!
Incorrect, Diesel engines for about the last 20-25 years have electronic control modules.
Mine starts with a computer, runs with computer, transmission shifts gears with its own chip, lights and door locks.....
I'll post the link to your FR story on this: Get yourself a 30-footer and go
No armor? I guess you could duct tape a bunch of phone books to it.

My information is incorrect. Sorry—not intentionally misleading.
Thanks for the correction.
Would love to spend a day hip deep in a big truck engine.
No problem, just didn’t want someone to have the wrong idea.
You are not as incorrect as Openurmind though. To state that it would take minamil effort to “refit” a modern diesel to run on mechanical fuel management is not even in the same zip code as reality.
It’s one of those “fun” professions, especially the big yellow iron equipment. Big Tonka Toys. lol
Phone books? Man your old.
Some folks say a motorcycle is the best way to go........

No Vermont is fine. He is basically right if someone has some mechanical knowledge of diesels. The basic engine and mechanical high pressure fuel pump system is almost as basic as they always were. If you can get fuel to it, even if by gravity, and have a starter to turn it over it will start and run as usual.
Fuel, Air, Compression, and it will run.
The only thing is you have to make sure you get electricity to the fuel cutoff solenoid. And even it can be rigged mechanically as open by default, but you would have to have a standard transmission and dump the clutch to kill the engine when you want to.
The only main issues would be any emissions control like EGR systems and if they have variable dynamic turbo chargers which both require engine management control. But these can be locked static mechanically with slight alterations and the engine will run even better without them functional.
So basically you can route (hotwire) around the whole vehicles system as long as you can get direct juice to the starter and fuel solenoid the engine will run. :)
I’m in the same zip code. You are talking to someone who can monitor a big truck engine management system by satellite anywhere in the states while they are loaded going down the road from my laptop. It’s what I do for a living, and what I was born into. :)
You are giving misinformation to fellow FReepers.
No pickup truck has had mechanical fuel systems in twenty+ years, the last being the Dodge in 1996.
Detroit Diesel, Cummins, Volvo, International and Caterpillar In trucks have been ECM controlled for 30 years. The engine will not run without an ECM or ECU.
Every single engine you are monitoring from your laptop is ECM or ECU controlled.
You would have to go back to a 3406B (1989) in Cat, a 855 (1988) Cummins, DT 530, DT 466, DT 360 (1996) in International, 8V92 (1987) in a Detroit and so on to get to a mechanical engine similar to what you have described.
I am not looking for a stupid internet pissing contest I just want FReepers to be properly informed.
I have diagnosed and remanufactured Diesel engines for 30 years, from 3500 series Caterpillars to B Series Cummins.
I stand corrected about referring to “all” pumps. That’s why I initially stated that the new engines are indeed computerized like gas engines. Actually you are right about the newer EDC injection pumps. They are completely dependent on engine management to handle the injection pump. And of course the trucks I am tracking have an ECM or ECU, couldn’t do this without one.
