check the fireing order of your plug wires u most likeley crossed a few wires and put them in the wrong order if u r looking at the front of the vehicle the front 3 cylenders are 2,4,6 starting from the front of the moter and the back 3 cylenders are 1,3,5 and the coil packs should be marked as to wich cylendr they go to if not the startin with the top coil pack the top plug wire pin is num1 and the second is num4 the next coil pack is 5 being the top pin and 2 being the bottem pin on the coil and the last coil pack is top pin cylender 3 and bottem is cylender 6. hope this helps

Timing belt. this is a major job. If you get a manual you can do it. but follow the manual to the "T". Also the manual will tell you what to check to make 100% sure that it is a timing belt.

backfiring through intake indicates 1 of 2 things that could be going on.1 is fuel pressure lack of fuel.but you say the plugs have fuel on them which to me indicates you have a spark problem.these are known for the ignition modules going bad which are below the igntion coils at the front of the motor.when they go bad they can affect all the coils or just 1 coil.if you have no spark at the plugs then the coils need to be checked for resistance both primary and secondary.you say the car won`t start so i`m guessing their is no spark.if the coils check ok then the module is probably bad.make sure the connections on the ignition module are tight and clean.
