Default Cranks but won't start, no fuel. Ecu or pump?

1993 sc400. Went to start the car tonight and can't get it to start. Getting spark, was able to run for a few seconds with starting fluid. Not hearing any priming noise from fuel pump. Tried to the bypass the fuel pump ecu through the diagnostic port under hood and still no start. Would it likely be the pump it's self then? Need help!

Update: let it sit for a day, tried it again tonight and fired right up. Any ideas?

you can try to bypass the pump by DIY'ing the sensor behind the driver seat, if not id recommend checking your ECU capacitors
