Anyone had anything like this the engine fires up runs fine, boost pipes connected, all new vacuum lines tested, new fuel line and pump but no throttle at all doesn't even splutter just stays the same, Ecu shows that the throttle is there and working I’m out of ideas cheers

No mention there of the throttle pot output.

That might be "drivers wish". Possibly.

What about DTC codes?

Got 4 codes
egr which is gone
Cruise control Unit
Vehicle speed sensor
Prefeed pressure sensor short circuit b+

Just for reference it’s gonna be a Standalone engine so I’m running it on the foor at the moment to text and the drivers wish is the throttle on and off I couldn’t post the video cheers

There you go. Prefeeed problem, that will be the low pressure fuel pump. Without that you have no start

But he says it starts and runs, just no throttle response.

Yes you're right. I hope that wasn't a senior moment!! I'm not senior yet!!! But it's probably still related.. limp mode.. etc
