I could be missing something here, but did you flush the radiator and is there a possibility there is an air pocket stuck in the system?

I see you've replaced the cap, sensor, thermo and fan relays.

Do the fans work when Air Conditioning is enabled?

Hi, first timer here...got a 1998 VT Series 1 and had overheating problems. Car kept stalling so i ended up changing the heater pump, thermostat, checked the usual basics and the next morning it wouldnt kick in to start. Everything seems normal and there's a spark but no go, possibly computer???. Only quote i had for computer was $500-$1000+ Can anyone help please???
