That will be a nice one once you get it up and running
I'll start with +12V to DME computer and injectors.
Do a continuity test on the following +12V wires to make sure there is no break in the wiring harness.
From DME relay socket pin 87, to DME computer pin 37.
From DME relay socket pin 87 to each fuel injector terminal.
If there is continuity on all, then you are ready to do a test for spark and fuel.
To check for spark, jumper DME relay socket at terminal 30 and 87.
Check for spark at the plug or at the coil wire while starting the car.
If there is no spark, you need to do a continuity test on the ground path of the ignition coil thru the ignition control unit.
To check for injector pulse, use a noid light on the injector harness.
If there is no pulse, check for continuity from other terminal of fuel injector to DME injector output terminal for each cylinder.

thanks. I've done the check on connectivity From DME relay socket pin 87, to DME computer pin 37. that checks out, but only with a jumper in place, doesn't work with any of the three DME relays I have in place.
