I sort of suspect the TPS unit as being faulty - however, don't know of any static test that I can do? Getting a new one also seems to be like looking for Rocking Horse Droppings Maybe we'll just opt for disconnecting the servo, and pinning the valves --- if we can get it started that way!!
Again - thanks, and any further input will be greatly appreciated.
Cheers,

Brid,

If you disconnect the TPS connector (turn off the ignition switch before doing this!), and then turn on the ignition switch, the servo motor should rotate to the "HI" position.

If it does not do this,check the battery voltage is good (below 10 v, servo motor may not work).

To check the TPS, disconnect the RC Valve servo motor and measure the resistance between the BU/G and the Y/R terminals on the Black PGM connector (wire harness side), should be 4-6 kohms

While measuring the above, also measure the resistance between the BU/G and the Y/BU terminals. TPS fully closed should be 0-1.5, , fully open should be 4-6. if the resistance is above, disconnect and check at the TPS sensor plug. If okay, then it's the wire harness, if not, then the TPS needs to be replaced.
