LDS engine stalls at low speed or take off.

[docharley]

My LDS engine stalls and shuts down when I try to get moving. If I up the idle the engine runs rough sounds like it developes a miss. Engine runs sluggish at speed and seems to be laboring. Anyone have any ideas. I am thinking fuel filters maybe?

Yup, if you are starting to trouble shoot, start with the filters. There is a very good TM "lds troubleshooting", you should look for it.

I looked and couldn't find a link to the TM. Check over on Jatonka's site.

I am goiing to replace the filters in the AM. Looks like it is going to be a challenge doing it by myself by where the filters are located. What is really concerning me is the miss that is present. Hoping that it clears up when the IP receives the proper fuel flow.

Thanks. Will download the manuals as well.

Well I am going to imagine you have a deuce, so the Primary (napa3511) is under the alternator on the pass side. The secondary and final filters (both napa3512) is on the side of the block behind(toward firewall) the oil filters. Have you checked the brakes and master cylinder out first?

I have a mechanic buddy that says, "you don't have to GO- but you HAVE to STOP".
Seems pertinent since you are trying to GO.

It almost sounds like a timing problem...

How long have you had your truck? When was the last time the fuel filters were changed? The fuel filters make a big difference on the deuces. Do you have a fuel leak? That can push fuel out of the lines and not into the injectors or suck in air and push air through the injectors.

 

[gimpyrobb]

I agree Bjorn, but I wanted to start cheap and easy.

 

[docharley]

Changed all of the filters. Primed and cranked engine. Still the same problem. Not as bad, But still the same problem. Cracked the fuel lines with the truck running at each injector. Fuel is making it there under pressure. I have a pronounced miss in one of the cylinders. Not getting a load of blow by in the crank case. Small amount. Onto what from here? Valves?

 

[docharley]

No problems with stopping. Master cylinder and brakes are good. No leaks.

 

[Flyingvan911]

Is your fuel fresh?

 

[docharley]

Starting to feel like I am

 

[dittle]

What are you running for fuel? Lots of threads on here asking questions about power loss only to find out that instead of running straight diesel people are talking about running all sorts of mixed stuff in their tank. Troubleshooting a diesel problem versus a mixed fuel problem is a whole different ball game.

 

[docharley]

I am running straight diesel fuel no additives.

 

[docharley]

Drained the fuel tank. Checked the flow of the electric fuel pump. Also check flow at the secondary filter. Went ahead and changed the air filter while I was at it.

 

[docharley]

I get verty little if any smoke at idle. I don't blow a bunch of smoke when running up the engine to shift at a high or low rpm range.

 

[docharley]

What tm's do I need for valve adjustment and timing for the LDS engine?
