The problem is the following, after 1 month without use during negative temperature winter the engine didn't turn, after checking if it was the battery and seeing cables overheating with using 2 batteries together i tried to turn the engine.
The engine is very stuck ( high gear, 1wheel on air trying to turn) .
The injections pumps only the middle one sends some fuel and is very stuck.
The high pressure injection pumps (number 3 picture) seems to be the cause of the problem , what chemistry can i use in order to clear the pumps ?
I can't really remove the pump because lack of a special tool to lock the spring as far as i know ( it shows on the repair manual)
Since yesterday they are with some decarbonizing liquid inside, because of rubber only rubber plastic safe products can be used correct?
The engine was running on diesel + vegetal oil .
From the looks of the tool, it should not be difficult to make.
A stiff rod, the correct size to insert into the pump.
Flatten the top of the rod and drill a hole, to insert a section of spring-pin material.
You can run seafoam in a Diesel to clean it up once you get flow. On my truck the directions were to fill a new fuel filter, start it to get it in the injectors, let sit for an hour, then restart and run it hard for 30minutes.
