greetings: 93 chevy p/u with 5.7L. stalling at idle . code 54 set today which is fuel pump voltage less than 2 Volts while receiving ref. signal. I'm looking for a diagnostic tree to trouble shoot or advise from the experts (you).

Thanks a bunch

Check your pm.
You may have a couple my pc acting up.
The second fuse on fuel pump is inline there by the fuel pump relay on ac housing area.
Make sure it is not blowed.
You need power on both sides for the pcm to pick up fuel pump signal and for fuel pump to run.
Does the fuel pump kick on?
Have you got spark to all plugs.
