Trouble shooting no start

[Duquette5]

Ok so I've let my project car ('00 Boxie) sit long enough time to dive in. In troubleshooting a no start/no crank condition this is what I've done:

Replaced battery w/new battery
Replaced ignition switch
Removed immobilizer and inspected - found some minor corrosion on circuit board de-soldered those joints and re-soldered them.
By-passed clutch switch

Still no start.
All electronics work.
When I turn the key all the way to start I can hear the MAF cycle and a high frequency buzz from the engine compartment, but no cranking.

With key on I can crank the engine by jumping the solenoid on the starter.

I have 12V on the battery side of the solenoid only, even when turning the key all the way over.

Thoughts and suggestions please...
