Ran great one day, parked overnight now it wont start. Not getting spark out of coil. Tested coil, is ok, so i put in a new ignition module, still nothing. One odd thing is after cranking i can turn the key almost to the off position and i get spark for a second, as the motor turns over on its own. It seems to me this would be the ignition switch, but is there any other tests i can do before going and buying parts

test for voltage to the coil with ignition "on" and during cranking.  If no volatge...it's the switch

 

Confirm by jumper 12v to coil positive then crank it.

 

if it then starts, coil, disty, etc.....are OK......Switch is bad.

Put a test light on coil -.

It should light up and pulse w/cranking.

 

Light but no pulse = bad module

 

No light on coil - or + = power problem

 

No light on coil -,but,lights on coil + = bad coil

I ended up grabbing a distributor from a junk yard and it fired right up, thanks for the help
