Check your earths.

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

My 1.1 Ecu was a Bosch all earths been checked could a Brocken knock sensor cut fuel and spark ?😀

I removed the immobiliser box from under the dash after I got my ecu unlocked will this cause any issue I disconnected it whilst battery and ecu where connected ��

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.

Okay so I now have fuel and spark and when I turn it over it fires once then dies.. every time I turn it over it does this any ideas ������
