1995 Oldsmobile Aurora V8 Front Wheel Drive Automatic

I have a 1995 Aurora. Three weeks ago I drove it to the grocery store and when I got back the car wouldn't start.
I checked all the fuses and relays. They were ok.
I had had the fueld pump replaced 3 years ago but I went ahead and replaced it again. Still wouldn't start.
I replaced the fuel filter. Still nothing.
I checked all the fuel lines and the engine is getting fuel but it just won't start.
It seems as though something is preventing the plugs from sparking, allowing the fuel to combust.
I am at a loss.

Thank you

Robb

Hi rmcass76, Welcome to 2carpros and TY for the donation

Do below and report back with your findings

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine atleast 3/16 away from ground-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, coil's resistances, cap and rotor, distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it
