Did you try replacing the DME relay? Likely they have it located under the passenger seat with the ECU. It triggers the fuel pump. It’s unlikely it is the crank reference sensors on the flywheel. That relay is a very common point of failure

you can check the plugs on those, and the various harness plugs, and under the seat the DME plug. its best to check reference on these at the DME plug. if no reading then try at the plug for the sensor itself. IIRC, there is an Ohm range you will get if the sensor is functioning/getting a signal.
