rocco still not starting-advice please?

[doubt at inwave.com (Nate Mellom)]

Is it not cranking at all, or cranking and not starting? I'd check the 
electrical portion of the ignition switch.  Sometimes the contacts go 
bad, and the car won't start.  Had it happen in my '84, sometime it 
would start, sometime it wouldn't.  I checked absolutely everything, 
someone on the list recommended the switch.  Swapped in a new one, and 
the problem disappeared.  There's a test procedure in the Bentley (I'm 
pretty sure, anyway), and in Poor Richards.  You might also want to make 
sure you put your spark plug wires back on in the correct order, if you 
installed them backwards, or even off one location, it won't start. 
While you're there, check the Hall sender connections at the 
distributor, again, a common failure that'll lead to a 
crank-but-no-start situation.  I had a bad Hall sender in my '81 a while 
back, and it drove me nuts.  It'd give me a random start pattern, but it 
would also just die for no reason.  One way I used to check my Hall 
sender is sorta of weird, but I have a voltage guage installed.  When I 
turn the key, the needle will jump to about 10.5v, hold for a second, 
and then jump to 11.5v or so.  The delay is the Hall sender charging the 
coil.  When the sender wasn't activating, it'd just right to 11.5v, so I 
could predict when the car wouldn't start.  Eventually I connected the 
voltage guage oddity with the start/no start, and deduced back from there.
