Have this car stored indoors for over 10 years. Ran when parked. Put in new battery, vehicle cranks, when turning key can hear multiple relays under hood engaging. Fuel gauge now not working, but put in 5 gallons of fresh fuel. Not sure but dont remember if I should hear fuelpump hum, but I do not. Relay in the trunk is working.

Disconnect a sparkplug wire or 2 and ground it to the engine -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, distributor pick-up coil, ignition control module, cam and crank sensors- Note: If it doesn't apply disregard it

Still no start. No fuel at rail up at injectors. Will sputter with starting fliud. No hum from pump in rear. Switch in trunk has no power on either leads. Can I overide and hook some kind of temp fuel tank to go directly into the fuel rail in the engine bay.

Did you test the fuel pump relay? Try powering the fuel pump direct from the battery and see if it comes on.
