Randy and Art,

Thanks for your replies.

I should have noted there is power getting up to the injectors which I assumed eliminates the underhood relay (Randy's second photo) as the problem point.

I've exchanged the underhood relay (plus a spare), fuel pump relay, ballast resistors and ignition stage module from my 89 740T into the 92 940 and visa versa. The 89 runs normally using the 92's parts.

But to be 101% sure I'll test the relay and injector voltage again. If it checks out, ECU?

Ken
