I believe that in '93, this trick works for checking the DI-
Open the hood, hold the gas pedal ALL THE WAY DOWN, and crank the engine for a few seconds. It won't start. Turn the key back to off, and listen carefully. You should hear the DI buzz for a few seconds. It doesn't hurt if you have an assistant on this one. If the DI buzzes, chances are good that it works.
Replacing the battery makes sense if it doesn't crank, but I'm assuming it is cranking. Are you sure that you are getting fuel? The way to tell would be to pull spark plugs right after a failed start attempt. You should be able to smell fuel. How do the plugs look? They should be a light grey, hopefully smelling of fuel. But if they look black, maybe the car has been running very rich, and is now running even richer.
The first place I think of is the crank position sensor. If you are getting fuel, then that probably isn't it, because the engine control uses crank position to know the engine is turning, and to turn on the pump.
Do you have a Check Engine Light? A TCS light? The engine is rotating when you crank it, yes?
Low oil wouldn't cause a CEL directly - oil level and pressure don't drive the CEL. But it could be indicative of some other sensor on the hairy edge of failure.
