p0171 !

ok so ive done a vacumme test that was at like 14. ive did a fuel pressure test and i do think thats where im haveing the probblem. ive installed a new delphi pump and new fuel/filter/fpr. now im getting only 20 psi max then drops off super fast. so i clapped the return line and samething. ive just the relay to make sure im getting the full 12v down to it.i know its only spose to get like 5v after crank and before right? could this be my injectors leaking super bad?? the thing is hard to start then clears it self up after running for a litt but seems like it wants to die to
