Been there done that, like to pulled my hair out.

Measure the voltage on the red wire of the Fuel Pump Relay 30 with the negative lead on chassis. Do you have 12 volts present? If no you need to double check the 25 amp fuse connection.

If yes either pull the 25 amp fuse out or remove the negative battery terminal, then remove the Fuel Pump Relay. Make up a jumper using 2 18 gauge wires (4 inches each will do it). Crimp two wires in one yellow male spade lug and the other ends are male blue lugs. Put that jumper so that the double crimp goes to 30 (Red) and the other ends go to the terminal with Yellow/Brown wires 87/1 and the other jumper goes to the yellow red wire 87/2. What this does is create the connection that the Fuel pump relay does when it closes. You do more than send power out to the pumps, you also send a voltage to the AMM. The pumps will start running when you put the 25 amp fuse back in or reconnect the battery. If the car starts up the issue is in the circuit that closes the relay. Since the AMM did not get power you will not start. Check the connections on your coil and the connector on the ECU up in there on the passengers side of the car.

If after adding the jumper you still have no start unplug the AMM after you pull the negative battery terminal again.

Put the negative lead back on and try to start the car. If it starts and runs rough kill the engine.

Take the negative lead off and then firmly plug the AMM back in. Try it again, no start bad AMM. Starts runs, bad AMM connection.

Next press down about half way on the accelerator and try and start the engine. Starts you may have an issue with the throttle position switch or Idle Air Control valve.

Hope it fires off for you.
