Here is what happened step by step

Replaced spark plugs
Started the car
I have noticed that something was wrong with the idle, and realized that I didn't connect last ignition wire (no 4cyl)
Shut engine off
Connected wire
Now car won't start.
Car turns, i can smell gas, but there no spark

Please HELP !!!

 

maybe you got the wires mixed up. 4 is the front of the car. start from right 1 to left 4
3
1 4
2

 

Checked all wires and fuses
I have not disconnected wires from a distributor, and was replacing plugs one by one

 

how was it idling when you turned it on? might wanna take the spark plugs off make sure nothing inside the engine was damaged.
