96 Fuel problem

96 5.7 engine with 118k

Ran last knight parked it and this morning would not start. Sprayed some starting fluid in the throttle body and runs until starting fluid is gone.

Hooked up fuel pressure gauge but I don't think it is working right because for some reason I don't see a valve in the hose adaptor to hold the schrader valve open. Gauge did show 0 pressurre and I did use a screwdriver to see if there was pressure and very little was present.

There is power at the ECM-B fuse. Testing the 87 terminal of the fuel pump relay I only get around 7volts and I have read that there should be 12V. I also tryed jumper wire from terminal 30 to 87 and did not hear pump run.

I believe it is the fuel pump but the 7 volts at the 87 terminal concerns me. I cannot afford to just throw parts at it right now.

Some advice and the problem would be greatly appreciated.
