   Was your 1.1 ECU a Marelli 48-P2, a Bosch M7.4.4 or a Sagem?

   Is the fuel pump working? You'll hear it when the ignition is on?
   
   Also you say there is no spark, take the coilpack off, and spark plugs out. Put the plugs on the coilpack and then get someone to crank it and see if there's a spark.
