Doesn't catch at all, or catches and dies? Any codes?

The wiring to the fuel pump (via drivers quarter panel, often corroded), the pump itself, and the sock/strainer in the tank seem to come up as reasonably common problems. Never dealt with them myself, but pretty sure I've read others having issues where there is fuel getting to the filter, but not enough to feed the engine.

This might help, I see the air flow meter/wiring is another possibility, I've had a no start after swamping the air filter and forgetting to reconnect the wiring at the AFM after drying everthing out, but that was more of a catch and immediately die.

Sorry for the orientation, I'm useless on a PC.

Take a paperclip and jumper the Fp and +B contacts in the diagnostic connector (the one on the firewall by the charcoal canister). Turn the key to ON, listen for the pump running, and you should be able to hear fuel hissing thru the fuel rail. If so, see if it starts.

Also check for any codes.
