doubtful.
I always feel better with a fuel pressure gauge on it....
the fuel pressure and delivery side of it is seldom the problem in my
experience.......
but it's good to know that part is right.

if that basic check isn't done, it's like working on an electrical issue for
hours, but never checking the fuses.
Would offer more but don't have a lot to go on yet.
