I'm assuming the starter rotates the engine, but it will not run. I'm also assuming the fuel pump works (new) and there's fuel in the tank. In that case, there are a few high failure parts that could cause the truck to not start. Some of these parts will make the computer throw codes, some of them won't.

First is the fuel pump relay. It should be under the hood in the power panel with other identical relays that control the horn, headlights and such. It will be a rectangular one, not square like an ice cube. Easy way to check: swap with another one in the panel and check the other thing (I use the horn). If the other thing works before and after the switch, the relay was good.

Next is the ignition control module. It is inside the distributor, under the cap and rotor you changed already. These have a tendency to make no spark as well as prevent the fuel pump from working when they go bad. I would rather go to a junkyard and get a used Delco ICM than buy a new knock-off, the off-brands just don't live long. Get a genuine GM part. You can pull your old one and they will test it at the auto parts store for free. Make sure they let it heat up for a few minutes if you do have it tested.

Hello I would think if you replaced all those components, It would lead me to say its the ignition module, Or Pickup coil, they are both located under the distributor Cap. Fairly Easy to change should take about 15 to 30 minutes depending on you mechanical ability. I sure hope that Helps you out. If not get back and we can do somemore trouble shooting, For spark,fuel pressure. Ect.. Thanks Hopefully that will get you going.

More than likely it's the distributor. They have a tendency to build up corrosion and rust and have personally went through the same situation three weeks ago on a suburban. Check to see if you are getting spark from the distributor first. Have the ecm in the distributor checked at Oriellys for free. It's under the rotor and has two 8mm head bolts with wires plugged in at each end.

The best way to help find the problem, is to have a fuel pressure test done on it, that will tell if the fuel pump is weak, or the fuel pressure regulator is malfunctioning. If the pressure is low, the fuel pump is weak,
if it is high, the fuel regulator is at fault.

I'm assuming you replaced the fuel filter when you did the pump.
You'll have to try to figure out if you are loosing fuel to the injectors or spark to the plugs to proceed.
Its possible something is failing inside the distributor among other things.
I'm also assuming you have checked the computer for trouble codes.

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.
18 Inspect Fuel Tank -- Fuel Tank Empty.
19 Inspect Carburetor -- Carburetor Flooded or Faulty Choke.
20 Inspect Distributor -- Worn, Loose, or Incorrectly Installed Distributor.

How about the pick up coil in the distributor? A trick we used to use back in the day was to tap the distributor housing with a hammer, key word tap. If the engine missed or stalled than the pick-up coil was replaced.

Did you check fuel pressure to make sure you are getting proper fuel pressure? If it will start with starting fluid then it has to be either fuel related or electrical. Are you getting power to your fuel relay? When you turn the key on can you hear your fuel pump come on? I would not use anymore starting fluid at all to try and start it other wise you cause major problems.
