One thing I'm a little unclear on Bob, I think that the Omex ECU switches the fuel pump relay on the -ve side of the fuel pump relay, I.e. what Omex call the fuel pump control output in the terminal 5b actually goes to earth in order to energize the fuel pump relay.....and thus upon powering up via the ignition switch a bit of timer logic in the ECU puts that output to earth for 2 secs to run the pump in order to pressurized the fuel rail, then, upon further operation of the starte/ignition switch cranks the engine and it fires up which , I guess initiates a permanent earth to terminal 5b ( "permanent" whilst the engine is running!)......sorry...thjs verbiage is for my benefit, I'm thinking aloud, time I was holding a cheap Chateaunuef du Pape instead of this tablet!
