Thanks to all for getting back,been in touch with a friend at Renault says this is a fault with them no rpm signal in ecu so pump not coming in,ecu removed and sent for checking/repairs

still would like to know if the launch is capable of reprogramming another ecu ? as anyone with a launch will know instruction manual is a joke but they still put out updates all the time with no information on how to use, would be quite apprehensive to try with new ecu in case it goes belly up.

Thanks Mark
