    Hmmm...cam sensor? Do they use the distributor drive as a cam sensor? Thanks for that i would never have guessed! So.. I have tried both ecm's...neither provide an earth for the MPR and cosquently it wont fire, There's no spark whatever I try but power to the Coil Module and driver module...can...

    Yep then thats ok... When the ECM that came with the engine didn't work we did loads of tests and came to the conclusion that the ECM isnt giveing the mpr an earth. I've wired in an earth and the mpr fires but doesnt trigger the fuel relay as it's earth also comes from the ECm. We have now...

    Right...a quick update. Ignition cut out switch had disconnected itself in the middle of all this...reconnected it and I now have 12 volts on the purple wire at the back of the ECM and at what i think is the DLC, and 12 volts on the MPR link/signal wire to the ECM. I do not have voltage at pin...

    I only get either 12 volts coming down the Ppl/Dk Grn or 7volts down the purple in the picture and to the ECM at pin 18.
