1995 Chevy Van (G20) 5.7L Single Point TBI Two Wheel Drive Automatic 142000 miles

This van was purchased used. The van sat for a year, but it started fine and ran excellent during the test drive. After purchase it suddenly died less than 5 miles away from seller. I checked the battery and it was dead, so I replaced it, but the van didn't want to start, it seemed to have no fire. I gave it a tune up (plugs, plug wires, distributor cap and rotor, filters, and oil change). Now it has fire and wants to start, but it will not idle, and dies if I give it gas, unless I am pumping it. A friend ran diagnostic and it says (code 54) fuel pump circuit. I need to know how I should begin repairs with this circuit and where is the fuel pump relay located. I chose subject electrical because diagnostics said circuit, but could it be a fuel filter or pump? I am NO mechanic.I can do minor repairs myself. ANY insight will be helpful, Thank You.

Welcome to the forum. Use a gage and check fuel pressure. Some of the national brand autostores used to loan out a fuel pressure gage. You can call and ask. As far as the relay, check under the hood, center firewall. The wiring colors at connector-- orange-- red-- gray-- dark green with white tracer-- black with white tracer. There maybe more than one possible location for that relay? Also, there should be a fuel pump test connector, close to battery, may be a red wire with electrical connector, nothing plugged into it. If you use a jumper wire with inline fuse, from battery voltage to connector, the pump should run, don't need to use the key.
