1991 Buick Century Please Help!

1991 Buick Century 6 cyl

Alright, I am needing help, I have a buick century that is just not wanting to start, while driving it all the lights on the dashboard came on and I couldn't get the gas going, so after having it towed home, we realized that there was no gas getting to the engine, so, we replaced the fuel pump, fuel filter, crank sensor, ignition/control module, relay switch, coil packs, even the injectors. No luck, so I put it in the shop they said a bad module so we replaced it AGAIN, and nope, still not running. So then they said bad crank sensor. Does this make sense to anyone? Thank you all so much!
