200clc loss of power

For example some systems are set up where if it sees high intake air temperature hi boost pressure it will pull the boot the fuel back and limit the amount of boost you can create. I would not think that it would limit it to the point of bogging the engine down or starving the engine for fuel. I'm going to ask again cuz I don't recall and I'm driving but you did State you checked all fuel fittings all banjos and some of those goofy rubber grommets that some manufacturers like to use you don't have any debris no air intrusion anywhere correct

Have you any means to place a vacuum gauge on your Inlet line to the lift pump I would think anything more than four to five inches is way too much

funwithfuel · Jun 18, 2018

And what kind of fuel lines do you have are they double wall vinyl or are they the old fashioned rubber lines w\ hose clamps or crimps

NathanSkallerup · Jun 18, 2018

They are the rubber fuel line hoses. And I don't have a vacuum gauge, so I can't effectively test that. I get what you are saying about the computer needing those numbers though. That makes sense. And yes I have checked and cleaned basically the entire fuel system. Even removed and cleaned all of the steel lines and installed with new seals. Like I said, I'm getting correct flow and pressure to the injection pump, so I'm really thinking that it has got to be something electrical controlling how much fuel it's actually giving the motor

Well I wouldn't try a bag of regular ice I don't see well I wouldn't dry a bag of regular ice I don't see what harm a bag of dry ice would cause

NathanSkallerup · Jun 18, 2018

That's a good point. I guess I'll have to see where I can some dry ice in town. That should at least tell me if it is the heat after running that is effecting the computer allowing it overheat internally

200clc you can check the active engine codes in the gauge located behind the cab..any active codes? I’ve seen de10 vintage ecu’s fail with no codes..but if you had something it would help with diagnostics..usually with that fuel system with those symptoms, if you’ve verified the low pressure system is good and replaced the pump..the ecu is generally the culprit..almost says that word for word in the book

NathanSkallerup · Jun 18, 2018

Well I really appreciate all of the replies from you guys. So much help here it's astounding. But it ended up being a cracked filter base in the water separator. Im not sure if the air it was sucking in was the reason I was still getting good pressure readings on the low pressure side or why it was reading that it was good. But I only found the culprit onon accident when I pulled the filter off to check and see if i had any crap accumulating again, and once the filter was empty I couldn't get the system to prime up again to save my life. So that's when I looked a little closer and findf a crack in the filter base sucking air. Nothing like spending a few thousand dollars to fix a 50$ problem right? Could have been worse I guess. But I really do appreciate all of the replies and wealth of knowledge this forum has to offer

Outstanding! It's always the last place you look.
You know, pump guy and myself usually recommend lightly pressurising the entire fuel system with compressed air. For whatever reason, we both neglected to suggest this step. Perhaps, because you reported maintaining fuel pressure.It may or may not have revealed that crack.
Well, sorry for the omission. Glad you found it.

NathanSkallerup · Jun 18, 2018

Oh it's ok. I tried pressurising the entire system to get it to prime up, and when even that wasn't working is when I got really suspect of something wrong in that filter base. But again, really appreciate it!

Thanks for posting the solution. I'm surprised it wasn't leaking fuel externally.

I am having the same issue with two Derate codes and one pump timing codes I could use some help I’m lost in this thing

funwithfuel · Aug 4, 2020

I would suggest opening a new thread. We got a guy for Deere stuff. Make sure you include model, serial, hours and attachments. Describe what's going on and what aggravates the situation the most and dont forget the error codes.

Wondering what you found out on your issue.

funwithfuel · Dec 9, 2020

Same suggestion. Open a new thread with model and serial. A good description of what is going on. There are guys here who know Deere. But they're not gonna troll zombie threads to help a guy out.
