Engine check comes on, Immobiliser indicator light on, car stops dead. Wait 1 hour and the car starts but engine check stays on. drives but cuts out intermittently. ODBll scan shows U0003 and U0004 codes.

I can't find a solution or decent explanation for these codes other than "CANBUS Communication Problems"

Any help would be greatly appreciated.

Thank you so much for that. I had started to suspect that but was now doubting myself... All I need now, is to know where that silly thing is on the engine? I have looked, but can't find it.

Hi Autospark. Thank you for your help before and boy, was that difficult to replace! My hands are just too big! I am hoping I can ask for some more help?
Now, with the Crank Position Sensor replaced (Ridex), the engine cranks but refuses to start. (Before, it started instantly but ran for around 10 minutes then cut and wait 30 minutes to start)
I tested;
Fuel pump runs for 2 seconds when ignition goes on and shows 10Volt on the pump test lug when I crank it.
Fuel rail gets fuel from the fuel pump and Injector pump, pumps through fuel when I crank it.
However, with the little overflow/bleed pipes removed from the injectors, no fuel comes out when I crank or when I turn the ignition on?
Also, now the Key/Immobilizer light no longer lights up when I turn on the ignition, or when I crank it...
The red fuel filter light stays on and I don't remember what it used to do before?
I would be most grateful if you could tell me what you think.
Gerard

All done, but now...
