Mazda MX5 1993? Import - Behaves like it is immobilised Archived Message

Hi all,
This car behaves like it is immobilised though I do not think it is a immobilised ECU. The car starts, after 3-6 seconds it loses injector earth switch.
The RPM and cylinder ID sensors produce lovely square waves. The injector currents are fine. TPS and air mass are within spec. Start signal to ECU is ok.
The over rev signal from the module is hovering at 10v, no switching (I don't know if this is correct?).
I am scratching my head. Can anyone suggest something?
Regards,
Job
