Your fuel pressure guage should read somewhere in the mid to high 30s.
Is this multipoint fuel injection or central fuel injection? How about
the fuel filter, did you change that? Maybe after sitting for so long
the rubber fuel lines have deteriorated a bit clogging the injectors?

It has tbi and 20 psi fuel pressure, good injector,new distributer and
still wont idle but injecter pulse just before it die's

I don't know if tbi pressure should be the same as mfi pressure, but
mfi pressure is supposed to be the following:

Key On Engine Off 35 - 45 psi
Key On Engine Running 28 - 33 psi

Could be a few different things, fuel problem, air intake problem,
electrical problem. I would scan for any codes stored in the
computer's memory and post them here.
