I need help with a 1988 Ford F250 Diesel 7.3L
 

International engine banks turbo 7.3L Diesel.
was running great then she started stalling out at every stop. Parked at home & won't start now. Possible fuel filter but I don't know how to change it. Any ideas? Also was told about spraying some ether in the intake for a quick start, watched some YouTube vids..seems legit but dangerous.
Thanks for the help
