Did some more troubleshooting tonight with lister Jay and came to a few
stumbling blocks. Still no spark but I think the problem is actually
deeper. There are two items that are confusing us:

While trying to pull the ECU fault codes, I was getting no power on the
red wire of the black connector (+12v) and I should have.  AFAIK this
comes right from the ECU, that cant be good.

Secondly, while trying to test the coil and power stage, it says to put
the LED between pins 1 and 3 and crank....the LED should blink as its
pulsing ground. It did not, the LED was on solid.  I *THINK* this is the
10V test though but Im not positive.

Jay grabbed 12V from somewhere else to pull the fault codes:
The only codes I got were 2111 and since the engine wasnt running, this
is expected (RPM sensor). Just to test the fault code system we
disconnected the TDC sensor and see if it showed in fault codes, and it did.

Im going to try to put my ECU in another 3B car to see if it works, if
the owner gives me permission. Short of that, any more tips on whats
next? A match and an insurance claim maybe? :)

Thanks in advance
Bob
