Turn ignition on / off. Next to the air intake is a valve that looks like a tire air valve. Push the stem and see if fuel squirts out. If not you have a fuel pressure problem and you need to re-check what you did.
Fuel pump
Filter
Shut off switch
Plugged fuel line or return

Obviously if it runs after using starting fluid it cannot be a spark issue. Without spark it wouldn't run at all.

A common problem that people overlook is the coil pack, you failed to mention replacing that. its what provides the actual spark to your spark plugs. if its malfunctioning then not all your spark plugs are getting a good charge and firing.

Is the fuel pump running? Take the gas cap off and put your ear by the filler. Now have someone turn the key to the on position (not all the way to start). You should hear the fuel pump run for about 3 seconds. If you don't hear the pump run, the most likely culprit is the fuel pump itself. Second possibility is the fuel pump relay.

might pull that cap again and see if the dist. shaft is loose
(side to side play) Sometimes the bushing wears out and the
magnet will hit the pickup,makes the spark irratic.Should have a new rotor with the cap,they also go bad.

Could be fuel or ignition related based on your description.
You would need to figure out which problem you are dealing with to proceed. Could be a weak fuel pump, or dirty filter, or problem with the injectors if it is fuel related.
Then there is the ignition system to troubleshoot if it is a lack of spark.
A weak coil, ignition module, cap and rotor, or spark plug or wire.

You've already eliminated the spark plug & wireset, distributor cap & rotor.
Sounds like your car needs a tune-up, specifically, the PCV (positive crankcase ventilation) valve, and/of the EGR (Exhaust Gas Recirculation) valve.

Components checked/replaced during a tune-up are:
air filter
motor oil
motor oil filter
breather filter
fuel filter(s)
fuel strainer
PCV valve
EGR valve
spark plugs
spark plug wires
ECM or distributor cap & rotor
cabin air filter
transmission oil filter
transmission oil
engine coolant
check all vacuum hoses and lines

Troubleshooting the no-start condition - from the 1990 Mitsu Mighty Max Repair Manual:

Priority Action Part Type -- Cause
1 Inspect Battery -- Battery Discharged or Faulty.
2 Inspect Battery Cable -- Corroded, Broken, Shorted or Poorly Connected Battery Cable.
3 Inspect Distributor Cap -- Distributor Cap Cracked or Burned.
3 Inspect Fuel Filter -- Clogged or Dirty Fuel Filter.
5 Inspect Ignition Coil -- Faulty Ignition Coil.
6 Inspect Wireset -- Worn, Damaged or Faulty Spark Plug Wire(s).
7 Inspect Spark Plug -- Incorrectly Gapped or Fouled Spark Plug(s).
8 Inspect Starter -- Starter Motor Faulty.
9 Inspect Fuel Pump -- Low Fuel Pressure.
10 Inspect Solenoid Switch -- Faulty Starter Solenoid Switch.
11 Inspect Fuel Pump Relay -- Faulty Fuel Pump Relay.
12 Inspect Fuel Injector Pressure Regulator -- Faulty Fuel Injector Pressure Regulator.
13 Inspect Ignition Switch -- Improperly Connected or Faulty Ignition Switch.
14 Inspect Starter Drive -- Faulty Starter Drive.
15 Inspect Fuel Injector -- Dirty or Worn Fuel Injectors.
16 Inspect Fuel Pump Strainer -- Clogged or Dirty Fuel Pump Strainerat.
17 Inspect Engine Control Computer -- Incorrect Operating Information Being Delivered and Sent From The EEC.

Find the pressure test port (looks like a tire valve) on the fuel distribution rail over the injectors and place a can over the open end of the valve. Press the inner pin to release fuel into the can. If the pressure seems to fall rapidly, replace the fuel filter. Is the check engine light on? Rent a scanner, read any code(s), and pursue to repair(s). A bad crankshaft sensor or camshaft sensor can prevent the injectors from firing fuel into the engine.
