I keep reading about a fuel fump test wire located under hood on drivers side, unable to find it yet. Have checked fuel pressure. There is none, no whine of fuel pump when ignition turned on, swapped relay in fuse box with working relay from horn (same part number). Have good spark at plugs, will start with squirt of starting fluid. Really need to check fuel pump, where is this elusive wire, or how else can I jump the fuel pump?

Did you check ECM B 20amp fuse?

Power the gray wire at the fuel pump connector from the battery and see what happens-if it comes on and the fuel pump relay is good and fuse-You have a problem with the computer fuel pump relay control circuit
