replaced the old spider injector with a new ACDelco one, Spark is there, Voltage drop checked while cranking and no problem.( 10.9 V ) Checked the injoctor connector with a noid light and no problem it is pulsing. the fuel pressure is 50 PSI.
while cranking I do not see a single drop of gas coming out of the injectors (popet) . my question is: is 50 psi is not enough pressure? if no what could be the problem? thanks for every one help..MK

I changed the fuel filter and no kinks in lines. I guess i get not much of choice at this time except changing the fuel pump. Thanks to all

there needs to be 60-65 psi fuel pressure or it wont poppit. I think you need a fuel pump, use an acdelco brand it will last the longest.

50 psi is plenty. I would look for something simple like a gas filter. I don't know if this happens jery often but it could be air locked. Air in the injectors keeping the fuel from passin thru.
