Hey guys definitely need your help on this one, I stayed up till 3 last night trying to get my car to run and i need it asap, I gotta work ! ...

situation

I attempted to swap cams yesterday, took everything out, got ready to drop the new cam in than i noticed a crack in the distributor side so i figured it'd be safer just to keep the same cam in, so i put everything back on ...

Turned key, nothing ...

So I think i did something wrong undo everything than re-install everything,

I turned key again nothing ...

I figured there's no spark, So i change the spark plug , Wires & dizzy rotor

I turn key again, nothing ...
So now Im at the point i'm at again, pretty much the rotor when the car is cranked ... So what could be the problem, timing ? One guy told me i may have had a snapped cam but the cam is still fine ... so please help me out guys ... I'm gonna attempt to re-do the timing again but I just wanted some more ideas on what it could be, thanks in advance - justin
