Engine fires and acts like it wants to start but won't.
What could be some of the causes?

I would start by checking fuel pressure.

Fuel pump cut off switch under the dash on passenger side foot well...they get weak and the slightest bump can trip them. Had that happen with my 88 Bronco 2.

Could be so much...time to learn the basics. My B2 taught me a lot about no start diagnostics!
