Fuel filter could cause the issue also.. it’s sounds like a fuel issue, but have you also checked and made sure you have spark on all cylinders?

There are plenty of reasons for a crank with no start.

1996+ Crank with no start check list
https://www.allfordmustangs.com/forums/4-6l-tech/336452-1997-mustang-wont-ignite.html#2984838

Examples include (but not limited to):
  • Missing CKP sensor signal
  • Missing fuel rail pressure sensor (FRPS) signal.
  • Missing MAF single or misstated/under stating MAF flow.
  • PCM problem
In the crank with no start list, note the part about noting what the check engine light does during cranking.

Here's some information on an affordable ODB2 scanner that might make short work of your problem. Could give quick answers to question like:
  • What is the fuel pressure
  • What is the MAF flow?
  • Is the PCM getting a good CKP signal (showing RPM's)?
