Ran fine last night, wouldn't start this morning

Need the spark chk first then we can go from there.
Betcha theres no spark, and I'll bet it's not the Ballast or timing jump.

My money is on the plug for the distr/coil connection or ECU.


Yep, they fail without warning. A simple jumper wire over it will tell the tale there.
I've seen cases where the engine rolled backward a bit when shut down allowing the timing chain to jump too. I hope thats not the case here.
