Right, update! I now know what the EDIS4 module is, found it on the bulkhead. Fitted my new ecu, no difference. The EDIS module plug has power on various wires going in to it, and the coil pack multiplug has power to the middle pin with ignition on. I dont really know which one is pin #8 on the EDIS though, there was no numbering system on the plug or module. Anyway can anyone help any further given this info? Whats my next thing to try?
