I suggest changing the pickup in the distributor. This is what fires the injectors. If you have a noid light you can check for pulse at the injector, but my guess is there is nothing signaling the injector to fire.
FUEL INJECTOR NOT FIRING COULD BE FAULTY FUEL INJECTOR.HOOK A NOID TEST LIGHT TO FUEL INJECTOR ELECTRICAL CONNECTOR. CRANK THE ENGINE WATCH THE NOID TEST LIGHT SHOULD BE BLINKING WHILE ENGINE TURN OVER.IF TEST NOID LIGHT STEADY PCM FAULTY NOT FIRING THE FUEL INJECTOR.IF FUEL INJECTOR DONT BLINK OR LIGHT UP.YOU HAVE OPEN WIRING CIRCUIT TO THE FUEL INJECTOR CONNECTOR.
It's not that difficult to replace.

Sometimes there is a fuse just for the injectors if none of the injectors are firing id check the fuse.
But first check to see if the fuel injectors click because if they do click it could be the fuel pump.
Are you able to figure out what the fuel pressre is at when you prime the system? You can do this by checking the schrader valve on the fuel rail by plugging in a gauge and see if it has pressure when you turn the key.
if the injectors dont click and you have fuel pressure check the fuse for the fuel injector system (depending on model fuel injector system.)
Cause you need to first make sure the fuel injectors arent firing cause it may be a pressure regulator problem or a fuel pump.
if you need further assistance or have a question about anything ive said please follow up with a comment and i will be glad to assist you further from there. Thanks and good luck.
So your saying fuel pump giving you pressure but ALL injectors are not firing. IF ALL INJECTORS ARE NOT FIRING AND FUEL PUMP IS A-OK THEN ECU IS THE PROBLEM.
However, if a few are not firing then its probably those injectors.
CHECK FUEL PUMP AND FUEL INJECTOR FUSE.IF FUSE IS GOOD.YOU NEED A NOID LIGHT TO CHECK TO SEE IF INJECTORS FIRING.YOU CAN BUY A NOID LIGHT AT ANY AUTO PARTS PLACES.WHAT YOU DO DISCONNECT FUEL INJECTOR CONNECTOR.HOOK NOID LIGHT TO CONNECTOR.CRANK ENGINE TO SEE IF NOID LIGHT BLINKS.IF YES INJECTORS FIRING.IF YOU GET STEADY LIGHT.PCM NOT WORKING NOT FIRING INJECTORS.IF YOU GET NO POWER OR LIGHT DONT WORK.YOU HAVE A WIRING PROBLEM.YOU NEED A HAYNES REPAIR MANUAL LOOK AT THE ELECTRICAL WIRE DIAGRAM.TO TRACE FAULTY WIRE.
