car wont turn over after failed header install

I tried to get my headers installed but i ran out of time..so i turned back and put in the original manifolds and cross over, now she wont start and im still on a deadline i basicly need this done within the hour soo any and all help will be greatly appreciated

soo here is some of the things that i think could be the problem

1) when taking out the front o2 sensor the prongs in the harness popped out, i dont believe any wires broke but im not sure if theyre in the correct order

there is four prongs, if they are out of order would that prevent the car from starting up? and if you can help me figure out the correct order thatd be great too, if not i can toy around

2) i left the crossover open where it meets the rear mani, i figured itd be no big deal but i dont know if its skewing the o2 readings thus preventing the start up

i left it open becuase the two bolts snapped in the rear manis flange and i couldnt get them out


im cleaning my spark plugs now hoping that it is just some oil/ grease that is not allowing the spark to transfer from the wires
 


02 sensor would not prevent the car from starting. start simple is the battery connected? did you unplug the icm under the coil packs to move the wire?
 
all i need it for it to make the 1/2 hour trip up to my mechanics shop while i go away on business, but as of now its not leaving the driveway

cutting out unless staying on the gas sounds like you have a big vac leak check the hose going to the break booster.

It is the big line that goes on the top of your blower to the big black thing behind your master cylinder.
