Will start and run but when you shut it off it will not start again
I've put this car in several shops, the fuel pump has been check, fuses have been checked, fuel regulator checked, I put a gauge on the fuel rail and the pressure will shoot up and then go way down when you apply a little gas. And its almost like it either floods its self with gas or does the opposite whenever you shut it off so when you go to crank it again it will not start at all. I have absolutely no idea what it could possibly be nor have I heard anyone talk about this, any advice???

Reviewed sidebar questions for help? Tried Ford Mustang forums? Whether older carburetor/distributor or electronic fuel injection, knowledge of fuel systems may best come from service manuals (Alldata.diy or Mitchell Data, both online). Less informative may be Haynes or Chilton manuals.

You got some conflicting info going on here. I need year Engine and trans info and any aftermarket mods to get a good path to start down.
Gonna need more data, so here some tests to try:
1, check the relay for the fuel pump and ECU for the pump
(injection systems cant "flood" with fuel like TPI or carbs, unless told to by ECU/sensor malfunction)
2 Sounds like a crank/cam angle sensor issue. Because of the lack of restart
(if the ECU does know where they are in time they will act like it "ran out of gas")
3 check the key tumbler. early rfid key systems have battery and sensors in the steering column
Along with about 50 other things. Sorry if I caused more confusion than help
