Nope, diconnecting and reconnecting speed sensor didn't do it.

Disconnected and reconnected all sensors...no dice

Put battery charger on and turned key...vrooom...it starts

Gol dang car !
Bugger! I though I had the answer for you.

What I think is happening is you have a voltage drop problem. A wire somewhere (maybe more than one wire) has a resistive connection and the DME is not getting enough volts to run correctly or it's not sending correct signals out.

This maybe on your supply rail to the DME, or it could be a sensor, or it could be the wire to the coil, or it could be a ground connection. Sorry, being intermittent, it'll take some time to find it. Get a schematic and a meter and check off each electrical connection methodically. In some cases (depends upon the signal involved) a few ohms resistance may be all that the problem is.

Cheers
