94 throttle body start up issues, continuing
 

My 350 is still giving me problems upon startup, i have fixed a gas leak but it still will shut down after a split second upon firing, more detail it starts up great but after a second or two completely shuts down, it wont even sputter or shake or backfire. Was told a fuel filter may be clogged? I usually wait for about 5 minutes or go tap the throttle body two or three times and then it will start and run just fine. Unless there is a short somewhere im all out of ideas. Already changed the pressure regulator, no help.
