Good day.

My cars wiring loom caught alight.

Fixed all wiring, Ring out everything with multi-meter.

Check pump relay, fuses.

Replaced knock sensor, Ignition pack.

The car does turn when key is turned.

Put petrol pump does not run, (petrol pump is working (tested).

No spark.

Can you please give advice to start car?

Regards,

Welcome to 2CarPros.

First, this vehicle isn't available in the US, so my technical information is very limited. Please bear with me with the questions. Most vehicles operate on the same principals, so I will try to work through this one.

Since both fuel and spark are absent, does your vehicle have an automatic shut down relay? Next, I don't know where the fire was, but on many vehicles, if there is no ignition spark, a computer will shut down the fuel pump. With that, does your vehicle have a crankshaft position sensor that may have been damaged?

Next, have you checked the relays to make sure there is power to them as well as the relay are good?

Have you checked for power at the fuel pump fuses and ignition?

Let me know what has been done. Also, make sure there aren't any ignition fuses bad.

Take care,
