88 blazer tbi problem

i got a 88 gmc 350 tbi i just bought. it used to be a buddys, When you started it it would run for a few seconds and die. if you held the throttle down it would run and act as if it were loading up. He put a fuel pressure regulator on, fuel filter and plugs. Now it will start for about 2 seconds and dies, after those few seconds its not gettin fuel to the tbi unit.

to me it sounds like a fuel pump. anyone got any ideas?
