Default No Spark, after some engine work

OK This is the initial Inquiary on my little problem from Today. I just put the engine back together after doing some engine stuff, timing, seals, cooling stuff ect. The only thing i touched in the ignition system was the replacement of the cap and rotor.

The engine is turning well, there's compression, there is fuel but no spark. What electronicly shuts off spark for safety sake or anything, would there be a low oil switch, coolant switch ect that kills ignition?

I was on my own so i was limited in testing various spots for voltage while doing this. any info or pointers would be appreciated

-Mike

How does the white cam sensor plug look?
Maybe it was falling apart and when you did the cap and rotor it broke.

Holy crap.... yeah you're right on the money.... actually that was the only plug i somehow forgot to plug back in lil bugger tucked way in under there hahaha! I had replaced almost all of the flex loom protective casing over most of the wiring in the engine bay which was deterioriated so that one lil connector slippefd the radar

well Thanks for the tip, I owe ya a beer next time you're up in Ontario Canada, ya saved m,e a few hours I'm sure it would have taken me a while to find that I think!
