I changed the fuel pump and the coil
The fuel pump and coil are on two different circuits.
The fuel pump is on the 20amp ECM fuse and the coil, ignition module, and injectors are on a 20amp fuse #10. But the ECM fuse could keep the coil and injectors from working.
You would need to test the fuses in the box in the engine compartment, and the fuel pump relay and coil for voltage and ground. The pump relay is grounded by the computer for 3 seconds when the engine is cranked.

also check your alternator, mine did the same and it ended up being the alternator
SOURCE: 1995 lumina cranks but will not start
Sounds like it has jumped timing, dont know which engine you have so could be chain or belt.
SOURCE: truck has no spark changed fuel pump fuel filter
Odds are it is the $20.00 ignition control module but that may be another fluke change out of parts. LOL
SOURCE: Mystery problem with blazer!!! PLS HELP ME!!!
fuel pump. I had a Lumina that did the same thing. I started with the fuel filter and that didnt help so i tried starting it with starter fluid and that is how I discovered it was fuel pump. Expensive at garage but my boyfriend and cousin did it using pictures from autozone.com. WAY CHEAPER!
SOURCE: Fuel stopped working, no fire to spark plugs
When I hear no fuel or fire I always think of ignition module first. The moudule tells the coil when to fire, and if you don't have fire at the plugs then the fuel pump won't run due to saftey issue. Take your module in to parts store and they will test for free.
