I had a similar problem with a diesel car that I owned--got hold of a spray can of a white chalk and coated the fittings that went to the injectors--found a small leak that was not visible--tightened up connection and the problem was solved.. It acted as you said--would start fine if you ran it everyday--but would not start if it sat for several days. This was a Roosamaster type pump--your might not be the same type.

UPDATE ON INJECTION PUMP
