Fuel Pump Problem

If someone could provide some insight it would be greatly appreciated.

Fuel pump:
The problem is that there is no power on the fuel pump relay pin 30. The fuel pump relay trigger (pin 86) has 12v when the key is on, so that part is working. I need to find out if the alarm system or an impact fuel cut sensor is disrupting the power supply to pin 30 on the fuel pump relay.

Last night my buddy and I connected 12v to pin 87 on the relay, the fuel pump started, therefore we know the fuel pump is good

Check to see if you are getting fuel at the schrader valve. I had a fuel pump problem too. my car would not crank/start.

Did you figure out what it was yet ? Did you get full up front on the line / pipe before the injectors.
