What maintenance and or repairs have been performed?
Is the check engine light on? If so are there any codes?
the injection pump has been replaced at some point... says "reman".. trans and converter are just rebuilt (but not solinoids) new fuel filter,, lift pump does work, thats how i filled the filter housing.... but dont know the preasure it should be or if the liftpump should be running all the time witch it is not ..
