Re: 351w 1979 mustang wont start
Dude,Is this motor injected or carbed? If injected,Check fuel pressure
at FR schrader valve w/a tester. There should be I think 60/70psi.
straight sys. pressure from pump to rail with regulator vac.port plugged and eng.off not running,Any less than it's the pump that's faulty.But if there's fuel up in vac. hose,replace regulator. Mech. pump you got should work on your 351w.
