To answer a few of the questions
Yes I have changed the DME relay I always have 2 spares so tried both and nothing
There is 12 volts getting to the coil when on run
There is fuel pressure also from cranking so think DME relay is good
Have confirmed no output from coil to distributor lead
Also no signal to injectors as plugged my noid light in to cyl 1
Next thing is to check sensors but I will replace them anyway because the cabling insulation has crumbled off. I am now wondering if I disturbed one of the sensors when I was working under the car doing brakes and AC hoses. I also gave it a good wash so maybe moisture got into the dodgey cables

Then read the "B" section from the Pelican Forum as posted up-thread (post #8) earlier here;

You can also test the sensors on the DME ECM connector; ref sensor on pins 25 & 26, RPM sensor on pins 8 & 27. It's a five minute effort at the most!
