Thanks - I had figured out that the front sensor only goes to the diag plug and only tested the resistance of the rear position sensor. I wasn't sure what kind of position sensor it was but was still a possibility. I "assumed" it was less of a chance when we found out it fires fine at higher RPM when the duty cycle is higher even after warming up. My first suspicion was fuel delivery too but immediately gave it a shot of ether and it still wouldn't fire, then pretty much ruled it out when I saw the timing light completely go dark when reving.
This machine does have the original overvoltage relay but it seems to also be okay as far as diodes (Zeners?), fuse and coil. I am not familiar with what this device does other than to protect the electronics/electrics against a runaway alternator but still may be a possibility.

Stevebfl - I had pulled and inspected the distributor and pretty much zeroed in on the coil or module after seeing the timing light go completely dark when on #1 and ALSO the coil lead. The puzzling part is that the spark is strong at higher RPM's when the load doubles or triples on the coil.

Thanks to you both for the help - thanks for taking the time to read and suggest possible solutions.

These parts are too expensive to try troubleshooting by trial and error, so if I can't find the part or if it is the module it looks like an after market ignition like Crane or some other may be cheaper than any one of the Bosch components. It appears that even the Bosch crank position sensor costs more than an aftermarket ignition system.

Again, thanks for the help. Every input helps.
