I’m having issues with my Renault Trafic, won’t turn over or even attempt to fire up, I’ve had diagnosed that the computer can’t get into the ECU whatsoever, needed some advice or anyone who’d know how to go about this.( service light, stop light, battery light on, but no engine light)

well if the computer cant get into the ECU because its not responding, then the ECU would be a good place to start
you can get ECU's but they need to be programmed to that vehicle

Try disconnecting the battery, then disconnect the Ecu leads check for corrosion clean if necessary. Reconnect leads then reconnect battery.
Remeber to leave ignition off for a couple of minutes prior to disconnecting battery otherwise the ecu will not be in sleep mode if you don’t then it can interfere with programming.

Have you tried a hard reset? Disconnect both battery leads then join them together for a few seconds, this will discharge any capacitors etc in the ECUs and hopefully give them a kick up the bum and start to work.
Hello, still trying to sort this issue out, I’ve ordered another ECU kit that comes with immobiliser and UCH, I’ve been told I Cannot for expample replace the uch alone and use the original immobiliser and ECu, is this correct information I’ve been given or can I just replace one of the follow 3 items
they are usually coded to each other, so would all need replaced to take it to someone to get them programmed
you could have got someone who knows what they are doing and it would have been working by now...

Sorry for stating obvious but shouldn’t you have just callled Renault for some advice? You’d have probably had the answer and fix by now :C
