I have been using an led voltage meter that also shows polarity. I clamp one end to the earth of the battery and test with the other end which shows the constant live on pin 2 of the unplugged plug. when I change over and put one end of the tester on the live terminal of the battery, pins 1 and 3 on the plug show earth. When I turn the key and crank the engine over the lights on my tester go out until i release the key. I have replaced coil pack, edis module, crank sensor and ecu and checked and soldered all wires where I thought necessary, all with no difference. I have been checking the plug to the coil pack, not the coil itself. The EDIS and coil both have power. Is there any way of 'hot wiring' the EDIS system to bypass most of the loom? So i could rule out any wiring problem from the fusebox etc. Or an idiots guide to test the EDIS multiplug to see what each wire should read? As I said, I know the EDIS and coil are gettting a live feed when the ignitions turned on.
