Check the fuel pump. It should come on for a brief moment when you turn the key to on. You should hear a brief buzz or whine from the tank, pressurizing the fuel lines. If you don't hear it turning on and then quickly shutting off, the pump may have failed or power is not reaching the pump.
You would need a voltmeter or testlight to check for power to the pump at the fuel tank electrical connector. Probe the fuel pump wire for power (when you have determined which wire is for the pump) while the engine is cranking. The pump should be running when the engine is cranking.. If no voltmeter or testlight, you could try hot wiring the pump with a spare battery set close by. Point is, you need to know if the pump has power to it before you go to the trouble of removing the gas tank to replace the pump.
Of course, if you have a fuel pressure gauge, it is simple to check the pump operation. If you have correct pressure, pump is good. If no pressure or very low, either the pump is failing or the fuel filter is plugged.
Can't remember if your '88 has throttle body injection or multi-port injection. If TBI, the fuel pressure should be kinda low-about 18-20 psi. On multi-port injection the pressure is much higher-on the order of 40-50 psi.
One more thing: If the pump isn't working, sometimes you can get it to turn on a time or two by just rapping pretty solid on the bottom of the gas tank. Seen it happen more than once, just not always effective.
If it is getting gas, next thing would be to check for spark.
Varify your statement by putting a mechanical
fuel pressure gauge on motor fuel rail schrader
valve.

Could be a clogged gas filter or failed &
blocked exhaust converter
