Have you checked the 2 flywheel studs that the reference sensors use? Damaged?

Have you traced the wiring from the reference sensor connection to the 35 pin connector with a continuity check?

The 35 pin connector, are all of the pins intact and none broken?

With the new DME in, have you tried to wiggle the main wire while starting?
It may be a broken connection.

The back of the fuse panel, do you have any wires that are burned, fried, brittle?

Are all the fuses ceramic style and not the plastic type. The plastic type warp with heat and do not make good contact.

I can only think it will be a simple fix that is preventing the start now that you have replaced the main parts.
