[DeTomaso] starter electrical system problem

[Pantdino]

Based on the pitch of the sound and where it seems like it is coming from, it really sounds like a relay on the firewall rather than anything on the motor.

Would a starter failure cause the relay to buzz? If so, why?

I'll have to crawl under there and have someone engage the starter while I 
listen.
The good news is the car was on the lift for changing the brake fluid when this 
happened, :-)

My perception is this:
  
 When engine was shut down one piston had finished its intake stroke and was 
sitting at the bottom with a cylinder full of gas vapor above it.
 When you crank the engine the piston moves up.  Plugs fire at BTDC, no?  So the 
plug fires before the piston is at TDC and the force of the explosion stops the 
piston and crankshaft at that point and the engine stops turning for a second 
until the starter moves the crank again.  I'm pretty sure this is what has been 
happening, because with the ignition switched off the starter spins the engine 
fine.

more than just a theory. 

Your starter, however, is still a POS, and now it's a *broken* POS. :>)
