I have an 03 lb7 truck has been in the shop for 2 months new injection pump installed worked fine for a week back to the shop on trailer. Now after spending all that money it will not fire back up. Got it started finally now truck smokes excessively at take off and when driving. It never did this before doesnt miss no white smoke.. Could it be the injectors, not sure if they were replaced before i got the truck or what.:help

do the paper towel test drop some oil of the dipstick on paper towel if two distinct ring show up injectors is most likely the cause...it shows there is diesel in there...
