Question type: Maintenance & Repair

if i put gas in the intake,it starts and runs till that gas is gone,some one told
me it is the regulator and spider,what tells those two things to start
working?is there a wire that might be bad?or maybe a line pluged ?
because i have 60 psi at the new pump,that is sitting on the floor,but only
30 psi at the schrader valve,before the gas gets into the regulator and
spider,and there are wires that go to the spider.

Most fuel injection systems require 45-60 psi. Try googling the specs first and see where you stand.
