I doubt the ECU will be faulty at all - moreover the wiring will be at fault! check the condition of the ECU harness plug and also under the drivers footwell carpet there are some connections/earths which can affect things.

You could try this too in the absence of any other help:

I'm no auto electrician here but I would be very surprised if the actual ECU was at fault.

Hi & thanks for replies whole story is ecu was sent away for re map when it came back car would not start so back again 3 times now they have put back my oridgional file on ecu but still wont go i think they've corrupted something when they removed the eprom they say not guilty so thats goingto be anouther problem for me later to try to prove that they foooked my ecu. James do you think that a spike from the corrupted ecu could wreck the bsi cos it looks like i will ave to get both bits unless someone can test bsi & make repair.

thanks alan
