Shot starting fluid to it. Will run briefly, then cut off. Replaced distributor, crankshaft position sensor, neutral safety switch, still won't start. Checked all fuses, fuses okay. Anything else I'm missing? Please advise. Thanks!

Hi:

If it starts briefly with starting fluid, the engine isn't getting fuel. First, check fuel pump pressure. Here is a link that shows how that is done:

https://www.2carpros.com/articles/how-to-check-fuel-system-pressure-and-regulator

Also, there is a fuel pump relay that is located behind the instrument panel. Check that. Here is a link that shows how to test one:

Also, check fuse 17 in the under hood fuse box. See picture 1

If the fuse is good, the relay is good, and there is no fuel pressure or it is very low, my first suspect is the pump. Here are the directions for replacement. The remaining pics correlate with the directions:
