freelander 1 accelerator dead

From your descriptions, I'm not really sure of the problems you are experiencing. It sounds like the engine will start and run - just not respond to the accelerator peddle.

I am not familiar with the TD4 - should the EML light come on with the other lamps for self test - but also go out with them? If so why is the EML light lit? Have you been able to read the diagnostic codes?

I believe the TD4 ECU has a 'limp mode', and I believe the ECU will also inhibit start for various reasons, but I'm not sure if there is ever a reason why the ECU would allow 'idle only'.

I'm sure if ever there was a case to get diagnostics on a car - this is it. However, if that is not possible, it does look like the first part to swap out is the TPS - can you get parts from a breakers locally for Freelander?

It looks like your ECU isn't supplying the 5 Volt sensor output. As to why this would be, can't say. It's possible (but unlikely) that all 5 V output are parallel, so if one is pulled to ground, then all would pull down. I doubt all 5 Volt sensor outputs are parallel though, as they normally have internal resistor to prevent such things.

Maybe your ECU has suffered 5 Volt regulator failure? That's very unusual though.
