Pulling the fuel filter and checking to see if there's fuel isn't sufficient go to autozone and get a fuel pressure tester you must have at least. 1991 A body vehicles have a fuel pressure requirement of 40.5 to 47 PSI

1991 chevy lumina wont start


Need to check to see if the fuel pump makes noise in the gas tank (humming when the key is cycled (aka priming the pump)) or check for fuel pressure at the rail with a fuel pressure gauge. Check if you have injector pulse when trying to start the car (purchase the correct noid light for your GM and see if it lights up when you try to start the car).
Need to check for compression with a compression gauge - cheap and easy to do. Or check for spark with a spark tester - also cheap and easy to do.
