in my experience ECU failure will be accompanied by a clicking sound from under the dash and the injectors.
I would check your spark. You have crank, if you have gas smell you'll have gas, if not check your electric lines to the fuel pump.
A dear friend told me that the fuel pump electric harness runs through the drivers' side rear wheel well panel and there's a like 14 way connector in there that includes your taillights and fuel pump.
That can corrode and go bad.
If you have gas (gas smell when cranking) you may have no spark; spark plugs, wires, coil, etc.
Three things keep your motor running;
-crank
-gas
-spark
and in the case of some of our older Zukis, prayers and love.
