I checked the return line.nothing coming out I replaces all the fuel filters the lines both to pump & return. replaced fuel .at start idle runs good up to 8-10 hundred RPM then puts out white smoke over black .. fuel runs off the exhost pipe & now its hard to start. then on the return nothing coming out it. its got a 4 way T or side ways H for the return . we did pull a injector line & she run good but started dying like starving for fuel...

before your journey home, did you change the basic fluids, like oil and coolant??
the white smoke has me concerned. the turbo could be an issue from sitting so long and very, very old oil.
the injector pump could be the real issue form all the years os sitting.
