BBB Industries have diagrams for free online. Check for power to fuses and relays to the injectors and a pulse signal to the injectors would be a first step. Check YouTube for "injector voltage test" will show you how visually.

Well, it sounds like it is a problem in the fuel pump circuit. A lot of problems don't set a code, but if you know someone with a code reader or scanner, or if you get it running to drive it to Autozone or O'Reillys, Pep Boys, or most auto parts stores , you can get a free code scan service. Only takes a few seconds, good to know if your engine computer has detected anything.
So you put a new pump in. If it turns on, it should put enough fuel pressure up to the engine. Here's how to check if the pump is turning on as it should to start the car: turn the ignition key to on, not start, and listen for the fuel pump to turn on for 2 seconds. You should hear a hum or buzz from the tank for about 2 seconds. If you do hear it, and the fuel filter is not plugged up, the engine should have enough gas to start. If the filter is not plugged up, and the only way to start the engine is with starting fluid, then the problem may be in the fuel injector circuit.
Now if you do not hear the fuel pump turn on (2 seconds) with key in on, then the problem is in the fuel pump circuit. This can be difficult to diagnose, not feasible without a voltmeter and a wiring diagram of the car, so you would probably need experienced help. If you put the pump in yourself, you are a good gear head. buy a digital voltmeter and a repair manual and go to learning while you fix it your self.

SOURCE: No Fuel??? Not starting.
You have fuel flow but the question now is are the injectors pulsing. Given the year of the truck my gut says your ECU, Engine Control Unit, has failed. Mitsubishi had issues with the capacitors in their early 90's cars, trucks SUVs. I have been thru this with two monteros and one 3000GT, very common. To check your injectors rent a set of NOID lites from Autozone our such. Remove an injector plug and itstall a noid light. Turn the engine over, if no flash, no pulse. Remove the ECU and carefully open it up. Look for the capacitors, there should be 3, look under the capacitors on the board; if there is a grease like substance, often time it has a green hew to it, then the capacitor(s) have failed. It may be possible to replace the capacitors or simply purchase a rebuilt ECU. Be ceratin the MD number matches on the new unit.
Please let me know your results and if this had assisted you.
