well it would help if you scanned the ecu and not the cluster to start.

That's the only error, I did scan the ECU as a single module and it had no errors. I can also read/write to the flash

Thanks mate for the reply, I will get someone to crank while I listen for the fuel pump priming.

I have no CEL lights on dash, says OK

Cant hear the fuel pump , put a phone in there while put key to position 2 just before start. Also cranked it, nothing on phone. Its a Walbro 450 , so its pretty loud. Only done few hundred km,

I can hear relays behind the dash etc.

When the key is on position 2 (not crank) the EPC and battery light is on. If I crank then stop they go away and OK is on the display

Checked the fuses also. Not looking forward to pulling the fuel pump out Tongue

What relay controls the switched power to the ecu?
