I have a safiri motor home has a 6.5 turbo motor. I bought it it set 9 years. I started it drove it 90 miles home. It started acting like it was taking on to much fuel. 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. I know its in thereturn some where what can I do I ever tried blowing out the new lines this has only 25000 miles not over that Iv been showed papers but also set between 9 & 10 years & yes I changed the fuel please someone help me if I get good I give my word I will donate thank you Kevin

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.
