Want to adjust diesel pump truck has no power

this requires a person with diesel pump experience. best have it done by an accredited diesel pump shop as if you get it wrong there will be engine damage

I believe that you must increase everything. Is not a good idea adjusting injection pump. Will be a great idea,if you get better best answer from directly from the Manufacturer.
Go and get support from them. Will be more efective.
God bless you

replace the boost sensor its about $60 that will clear the PO236 codes (i beleive that was the code)
Duralast part # is su129 and has a lifetime warranty. located under the "turbo power" engine cover if you havent removed that yet take it off and leave it off reduces heat
sounds like your vacuum pump is bad remove it, buy a 99.5" serpentine belt and do a mechanical wastegate. adjust the spring to the boost you want. good luck

Hi Sarah, I'm guessing that the pump you removed is the diesel injector pump. I'm continuing with that assumption. When you removed the pump to attend to the seal did you set it to the match marks which are on the pump housing and the front of the engine where the pump fits in? Timing a diesel engine is shall we say, tricky. I think before we proceed let me know exactly what job you carried out on your vehicle? Describe it tome in detail and then we'll go from there.

Hello, I owned a similar motor. They were underpowered and had a reputation for that. About all you can do is have someone check the Injector pump pressure and to time the Injector pump.

Timing the Injector pump will change the fuel mix. Just as setting the timing on a gas engine, you can lean out a diesel motor by changing when the fuel hits an open Intake valve. Or make it richer by the same method. On your motor the Injector pump is gear driven. There is an adjustment for the setting and you really need to know what you are doing.

You can also try to reduce backpressure on the exhaust system. This would require a different muffler and the larger you can make the exhaust pipes from the headers back, the better your truck will run. There is a limit. You have a governor which limits the top RPM. Diesels are a low reving engine with about 3000 RPM tops.

Your differential is another factor. There were some 4 something and 5.33? rear ends. The automatics were horrendously slow. Since your model still has the old time Ignition and mechanical Injector, the "Bulldog" and electronic aftermarket gadgets are not compatible. My truck would not hit 70MPH.

You are using a 27 year old truck. You may have to upgrade to a newer model to get the power you want. Go to a Diesel specialist for your adjustments before spending money on the exhaust. I hope my Solution is helpful, and that your modifications work out.

Better would have been to get the diesel injectors checked too.( Cleaned and calibrated )
Hope the injector pump timming is set correctly!

losen the bolts at the pump flange where it bolts to the engine block and rotate towards the engine about a 1/8 inch also adjust the linkage stop screw inwards no more than 1 1/2 turns

do yourself a favor and take the truck to a fuel diesel injection shop the larger nut is just a cover but the smaller one is an adjustment if you remove either on you could damage the pump

lol inside the gas tank

Did you come right with the drawing?
