in the cab where the throttle cable connects to the pedal Is where mine had the most play, check to see if its slipped like halfway off the pedal, maybe depress the pedal and have it help down at full and then look at your injection pump to see how much throttle you are actually using possibly?

It sounds like it's revving up a little slow but my phone speaker is kinda bad. Any smoke? Blue white black ?

Yeah, bit of a delay there.
How's it start?

It appeared to fire right up in the video?

 

[79jasper]

Guess I should've been more specific. Lol
Like how's it start cold vs hot?

It starts about the same
Started it the other day after sitting for 3 weeks at about 48 degrees and it sounded the same. The glow plugs appear to be working fine

The throttle response appears to be sluggish though

Could be an issue with your governor assembly in the pump. How long has it been doing this?

 

[Tim lindell]

Not sure I just bought the truck

 

[Thewespaul]

Can you take a video driving it?

When did you last change the fuel filter??? My wild ass guess (wag) is that probably is dirty and can't supply enough fuel to run any load on the engine like you mentioned.

You say the throttle response is sluggish. Is it the engine which is sluggish, or is it actual truck movement? Try revving the engine by advancing the throttle from under the hood. That is to say, bypass the go-peddle and the throttle cable when you tell the engine to rev. This will help either prove or disprove the first step in the process.

Watch the video.

Alright so I finally got to mess with my truck. I believe i found the issue. First I bypassed most of the fuel system by running the inlet line from the mech lift pump into a 5gallon diesel tank.This didnt seem t help much but it eliminated most of the fuel system. After that I bypassed the filter housing assembly by running some 3/8" line from the outlet of the lift pump onto the inlet line of the IP. As soon as I did this ( and primed the line) there was a noticeable increase in performance. I ran the truck a couple of miles down the road with some diesel clean in the 5galloms of diesel. The longer I drove it the better it got... So long story short i want upgrade that entire housing and switch to an electric lift pump. Does anyone have any suggestions, preferably an all in one assemble thats not crazy expensive(ie <$300). I plan on replacing all flexable fuel lines with clear lines to be able to view the system. And yes I tried replacing the fuel filter twice prior to bypassing. Any help would be greatly appreciated. As is sits my tuck can finally spin the tires in gravel but can mostly maintain/ increase speed up a hill at 45mph, Still a little sluggish but i think actually getting fuel and running a cleaner for a while will assist this plus an electric lift pump.
