No Spark on FD

Searched on this one and have yet to see anyone with a similar problem

The FD has been parked for about a week. I went out to start it up two nights ago and as I started cranking...................it sounded normal for the first second, but then it just started whining over like it was not firing/flooded.


my fd usually starts first try with minimal effort. Now it was not even trying.
Long story short, I pull the plugs and they are pretty nasty and wet so I replace them and do a ghetto comp test in the process. Even bumps on all faces.
Also do the normal unflood procedure.

Still nothing. Hook up my timing light and getting no spark. Pull the a plug and ground it to make sure. Still no spark.

So my question, why would I lose spark after sitting for a week?? What could it be.

I'm gonna try and get down to the coils today and see if its something obvious.

any other ideas??

oh yeah, my PFC sensor check came back fine

thanks

do all plug show no spark? If so then go for something common to all of them - ie power, fuses, ecu etc. If its only one or two then go for plug wires, coils.
