The '92 did not have a crankshaft sensor, so don't bother looking for it. You say you have spark and fuel, sol thats a start. Have you checked your fuel pressure? You have to have minimum pressure for the fuel system to operate properly and inject fuel into the cylinders. So I'd say first thing is to check fuel pressure and compare it to the required specs.

Just like Blazes says,
Borrow or buy a fuel pressure test kit at your local auto parts store.
You need to see 55psi or better when you turn the keyswitch on.
Here's where you check the fuel pressure.
