1996 Toyota Tacoma no fire fuel too much at times

No fire:

No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs,coil's resistances,cap and rotor /distributor pick-up coil, ignition control module, ECM,Ignitor camshaft and crankshaft sensors and computer. Note: If it doesn't apply disregard it

Too much fuel

Could be the coolant temperature and oxygen sensors, leaking fuel injectors and fuel pressure regulator, and fuel return line clogged-
