i am under pressure ! my throttle body 93 astro shuts off while driving and at idle
i have 15 psi at t. body- is this enough
i have cleaned ignition conections and all conections on motor
when wont start there is no spray at injectors
i can hear relay and pump cycling for 3-4 seconds
when i crack the fuel line there is fuel / but what should the psi be
when it is running it runs great

chec your fuses. Do you have a engine light on? I could be your tps, or something similar. The pressure sounds about right. Get a Haynes or Chiltons manual. One of the 2 should have the pressure in it. If you don't want to spend 15 bucks call a dealership and ask them they should be able to tell you.
