Car wont start

[maxwell6]

Hi need some tech help. I launched my mustang 2002 gt 450rwhp supercharged today and when it hit i heard it pop then it shut off. tried to restart but not getting any fuel pressure at the rail. When i turn the key on I can hear the fuel pump but no pressure at rail. before that it ran good with only a cold start problem. Any help would be great thanks in advance.

You sure it's the pump running? Odd time just a tic of wheel hop can trigger the pump safety shut off switch in the trunk, you checked it?
Cold start problem, what pump you running / return or returnless / does it have PPRV delete?

Running a focus high volume fuel pump returnless with pprv delete. Checked fuel reset its not tripped.

Check the filter for a blockage, if ok, tank needs to come out. If you hit it with less than approx 1/3 of a tank, can take a mouth full of air and quit.
PPRV delete is why it's slow to start in am, nothing to worry about.

On a side note, while the Focus pump is very capable, leaves little to no margin of error.
