On my way to my friends house to weld a hole in my exhaust, I was just going down the road, and i noticed i was slowing down (slight grade in the road maybe 5

 so i gave it some gas and it just slowed down even faster sounded like it was running, but it wasnt.  i let off the gas then it died, now it wont start.  
while the car was slowing down it sounded like the car was like in  2 gear idling down from driving speed.  I smell fuel, just changed coil packs.
Can plug wire all of a sudden quit on you going down the road?
if not wut else could it be?
btw my car did not throw a code.

Well swapped some plug wires from a known good vehicle, gettin nice hot, blue spark.  Also changed the fuel filter.  The car is getting fuel to the motor.  We noticed a small leak around the inlet side of the fuel rail.  This wouldnt cause a no start condition.  
All the car does is crank and crank, until you put your fut on the gas pedal then it backfires thru the throttle body shooting a nice little flame out of it.  
it seems as if the engine is out of time, but I just replaced timing gears, chain, and tensioner.  everything was installed and torqued properly.
