Hmm... Before I discovered what a muppet I had been with getting my CPS stuck inside the bellhousing the thing would run on ether. That, and the scan tool showing RPM would seem to suggest it's not the CPS. Even a non shielded wiring issue should still fire on ether. Same argument re injectors. Ether will fire regardless, unless it's a compression related issue, imo. Is the cam actually turning? Longshot, I know, but...

To me, and I'm far from expert, your statement above is highly telling.

Yes the cam is turning, the injectors are firing.
Discofender made a pertinent point, connecting the fuel line failures with odd compression numbers. i find it hard to believe that copper washers could leak enough compression for diesel and ether not to fire......but in the absence of any any other explanation....
The chain looks in good condition, definitely not worn enough to have jumped a tooth.

Still weird it won't kick on ether. Diesels are known as compression ignition engines. Makes no sense that ether won't at least cough. Injector washers would have to be seriously stuffed imo. Is there diesel in the oil?
