After you "played" with the timing did you remember to tighten the distributor hold-down bolt? And please explain the reason why you decided to play with the timing.

No the bolt was left snug but loose for adjustment and because it was 180degrrees the wrong waywhen purchased . I've yet to actually pull a plug to ensure there's no spark yet but certain nearly that it dosnt

It sounds like your distributor spun when you stopped at the light. The sensors would have stopped you before you got out of the driveway if they were the cause. Try moving the cap one way and then the other to see what happens.
If nothing, go back to basics. See if you have spark and fuel.

The modual thing I just replaced was from o Riley and has lifetime warranty but was only 11 bucks. Ac Delco is the cap and I'm unsure of the rest was only told it was all replaced before buying car so yeah damn

Rock auto has Delco stuff at decent prices, and you can usually find at least a 5% coupon code if you search online.
