Got an on going issue with our 1993 6.5 wrecker. No pulling power at all. Lets start of by I have replaced the injection pump, supply pump, vacumn pump, boost control sol, computer and rebuilt the turbo. Its our wrecker that has been this way for years now. I was told it ran great till the first pump went down. It starts fine and idles fine. No power at all, no black smoke and acts as if its starving for fuel. We have a 6.5 mechanical in another truck that's turned up 20% and runs like a beast but not this one. Any help or ideas would be great.

 

sounds like u need to do the timing on it..we had one that the timing marks were lined up ran but ruff once we set the timing on it it ran like a raped ape....just thinking here ...scott

 

Tried that with the ol tech 1 and tech 2. I tried it at 0 and 6 before. Is there anyway it could be the injectors. I have read that they pop at 1800 to 2000 psi.

 

could be if they pop off to early then it wouldnt atomize correctly..causing smoke...scott

 

A 1993 wrecker? That should be mechanical and no computers, or did you mean 1994?
